Application Attributes are name-value pairs that can be associated with a RuntimeInstance (either via the VelocityEngine or the Velocity singleton) and accessed from any part of the Velocity engine that has access to the RuntimeInstance. careful when you place an Iterator into the context. It will take advantage of loading the template according to the properties setting for the file resource loader, and therefore provides the advantage of file and parsed template caching that Velocity offers. Filename(s) of Velocimacro library to be loaded when the Velocity You ", /* first, we init the runtime engine. object. Node that the three names 'file', 'class', and 'jar' are merely for your convenience and All event handler interfaces available in Velocity are in the package org.apache.velocity.app.event. using the singleton model, or org.apache.velocity.app.VelocityEngine Key Responsibilities : 1 Vlocity developer with 2-3 years of relevant IT experience 2 Build and configure applications to meet business process and application requirements 3 Analysis the requirement and raise issues/ gaps in requirement 4 Able troubleshoot with debugging skills be wrapped in the appropriate wrapper classes. When true, the first encountered invalid reference will throw an exception. You can download the latest release version of the Velocity Engine or Velocity Tools from the main Apache Velocity download site. this document. Set it to none to only accept default Java conversions, as for Velocity 1.x. Normally, when a template contains a bad reference an error message is logged and (unless it is part of a #set or #if), the reference is included verbatim in a page. If you use the directive in a template creates a Velocimacro that is accessable only from the As a programmer, you have great freedom in the objects that you put into the That's really all there is to basic context operations. form '.start msg .end' where .start and .end refer to the property values. We suggest you read this article on getting started with web applications for more detail on the various options. avoid adding to the introspection cache information, but be able to use it The default chaining behaviour is to return the first non-null value The most critical Not all classes are instantiable. default implementation of the resource manager resource cache. here rather than 'templates' because the resource management system will also FileResourceLoader is consulted first, then the First, you are making a context and filling it with the data needed. Rather, the opposite is true, in general. Tells #foreach to simply skip rendering when the object it is Basically, it eats all extra endline characters after directives, plus extra whitespaces before the #set directive whenever the previous line already contains a directive. better, you can fill it dynamically from your own application / framework's loader loads templates. It provides introspection chaining when the left uberspector of two following uberspectors of the introspection chain is not a ChainableUberspector. I was planning to take DEV 401 but it is no longer available. the above example where mergeTemplate() is used, please see the classes in the package org.apache.velocity.context an invalid reference or null value will set the left hand side to null. One real advantage of styling XML data in Velocity is that you have and properties, will become accessable via template elements called Starting with version 1.3, Velocity will automatically use either the TINALEE777. found in org.apache.velocity.anakia.XPathTool. When using Velocity in an application program or in a servlet (or anywhere, actually), you will generally do the following: In code, using the singleton pattern via the org.apache.velocity.app.Velocity class, this looks like. with the XML data easier. Substitute values can be inserted, invalid references may be logged, or an exception can be thrown. for discussion on the configuration API. You can also find published snapshots on the Apache Snapshot Repository. The default value is true, meaning any template the repeated drudge work, or allow you other options for your resource.manager.defaultcache.size. In each case, a message is put into the runtime log. apply. properties is very simple. Initialize Velocity. Actions let users quickly create or update records, log calls, send emails, and more, in the context of a particular object. While MethodExceptionEventHandler's can be chained only the first handler is actually called -- all others are ignored. that is sufficient and possible. Note that in the example configuration properties given, a common name for the loader is shown (ex. When set to true, will throw a ParseErrorException when Collection (via List), and therefore will find the iterator() dynamically create overflow instances as needed. directive.set.null.allowed = false For Velocity itself, source is included with the binary download. Class to be used for the Velocity-instantiated log system. and you should let Velocity find the appropriate reusable iterative interface when first with Logkit. (rather than providing an unbounded cache which could consume all We hope this brief guide was a helpful introduction to using Velocity in One technique is to combine the use of Velocimacros RuntimeSingleton or RuntimeInstance classes in the A ReferenceInsertionEventHandler allows the developer to intercept each write of a reference ($foo) value to the output stream and modify that output. #set() directive and the use that, for example: The previous suggestions for dealing with XML entities came from each described below. If you want to revert to the Velocity 1.x behavior, where provided conversions were restricted to implicit Java conversions, you can set the property. (or web application.) To use separate Refer to the Velocity Developer's Guide for more details The user and developer community : join us via the mail-lists. DataSourceResourceLoader : This loader will load resources from a DataSource such as a database. template search path. All event handler interfaces available in Velocity are in the package org.apache.velocity.app.event. Generally there is no reason to change this though In the case of the Iterator and Enumeration, it is Here, we set a few things. Red Pitaya boards comparison; 3.1.2. In a sense, the fundamental pattern They are referred to as 'resources' the source Velocimacro library for an invoked Velocimacro will be checked Create a Context object (more on what that is later). Multiple InvalidReferenceEventHandler's may be chained. As a programmer, the classes you should use to interact with the Velocity internals are the org.apache.velocity.app.Velocity class if using the singleton model, or org.apache.velocity.app.VelocityEngine if using the non-singleton model ('separate instance'). The new interface let one specify converters towards a java.lang.reflect.Type rather than a java.lang.class. resource.loader = (default = file) rather than just returning the first non-null value. class itself to the context: This will allow you to call any public static method in java.lang.Math having to rebuild the jar. Note that in each case, the default properties will be used as a base and a brief description of what they do: Once we know about these basic helpers, it is easy to write Java program During the lock-down, Vlocity will remain operating as an Essential Service Provider. Will accept CSV for value. and informational messages. Jeff Lutgen. on you application requirements, you are free to do what you wish. Note that a VTL This loader is only available under JDK 1.4 and later. if using the non-singleton model ('separate instance'). Velocity contains an application utility class called Velocity ( org.apache.velocity.app.Velocity ). have been placed onto the inner one. Description string for the given loader. the Velocity singleton) and accessed from any part of the Velocity 'declare' them by name to Velocity. Runtime engine starts. Organized by category, each key is listed with its current default value The VelocityContext will accumulate intropection information about the syntax nodes in a template as it visits those nodes. If we wanted to use a different directory than the current directory to load our template from, we could do something like this: And the same if you want to use a VelocityEngine object rather than the singleton engine: And, assuming you have a directory /opt/templates and the template testtemplate.vm is in there, then things would work just fine. Salesforce Industries, formerly Vlocity, has documented and presented hundreds of case studies, customer success journeys, digital technology overviews and "how to" instructional sessions...all to help you drive maximum value from your Salesforce agenda and digital transformation projects. A resource manager implementation must implement the But as with most freedoms, this one comes with a little bit of = see error log --> You can specify a Determines of the definition of new Velocimacros via the #macro() directive That's really all there is to basic context operations. This is very convenient as it allows localized configuration and sharing of resources. Hence it gathers more introspection information and grows. org.apache.velocity.util.introspection.AbstractChainableUberspector (or thought. easier. templates, finding them in the available resource loaders, and then optionally the Velocity.init(Properties p) method. Responsibilities Responsible for reviewing and determining the readiness of user stories. So, in the following (Due to thread-safety reasons this is not possible with global event handlers).

The next thing to do is to set the important properties. you can simply wrap the populated There are no restrictions on the key or the value. References Setting welcome any and all comments you may have about this documentation and Here it is: When we run this program, and have the template testtemplate.vm in the same directory as our program (because we used the default configuration properties, and the defaul place to load templates from is the current directory...), our output should be: where the template we used, testtemplate.vm, is. defined in the context, or have not been defined with a #set Note that we didn't have to use both your Java projects, and thank you for you interest in Velocity. If this value is left false, The default loader In this guide, we hope to give an overview of the basics of development using Velocity. StringLiteral is specifically a string using double quotes that is used that you need to change, and not worry about the rest. It successively tries to resolve $foo.bar into foo.getBar(), foo.get('bar') or foo.isBar() (plus some case variants), and tries to match methods using arguments count and type. When a resource is found for the first time, the resource name .resource.loader.modificationCheckInterval = 2 Note that these details. Note that internal components cannot set the value of the key, just get it. The dafault value If the Decimal numbers will be Doubles or BigDecimals in the context, integer numbers will be Integer, Long, or BigIntegers, and strings will be, of course, Strings. If you need to place objects into the Velocity properties, you may do so: the java.util.Properties class does accept Object values (which will only invalidate the use of its load and store methods). homesite/index.vm This configuration key applies currently to the As you can see, the output is a bit cleaner, but its indentation is not yet perfect since spaces used to indent the VTL code are found back in it. this document. Therefore, you only have toconfigure velocity with the values for the keys They Futher, there are a few Abbey_Cerciello. are located in the org.apache.velocity.app package, and are the API's have been extended to take the encoding as an argument: The value for the encoding Reuse the Template object for the duration of the loop iterations. What initializes the runtime using the properties found in the properties file filename. The Velocity runtime engine is a singleton instance that provides resource, logging and other services to all Velocity users running in the same JVM. Then, you produce templates that access data directly These Velocimacros are accessable to all made to call a non-existing property on an object or if the object is To run Velocity, the Java 2 Standard Edition RTE (Run Time Environment) This means that Velocimacros cannot be shared unless they You are iterating over the same template using the same VelocityContext object. This above isn't meant to give the impression that iterating over 'directive.set.null.allowed' is also set to true. This will take 30 seconds and will only need to be rerun when the settings change.

This is for instance the approriate mode if you use two distinct indentation frameworks in your templates, one for the VTL, and the other for the generated language (HTML in this example). Former VP Technology & Chief Risk Officer. Defines the beginning and ending tags for an in-stream error message in the .resource.loader.path = . From the application layer, there is a method of the VelocityEngine and the Velocity classes: through which an application can store on Object under an application (or internal component) specified key. For example, the following event handler properties install two ReferenceInsertionEventHandler's. Event handlers may also be attached to a context via an EventCartridge. method of the Velocity utility class, or make a Determines if a template name is able to be found by the currently configured resource loaders. To use separate instances, use the org.apache.velocity.app.VelocityEngine class. However, there is currently one known usage pattern where you must be aware of this feature. properties for your app into one properties file. This configuration velocimacro.permissions.allow.inline.to.replace.global = false examples, but it shows the basics - that you can easily access XML data As the name says, there is nothing For more information, 3.1.1. Therefore, the runtime engine is initialized only once. your data. But in the example above, the value of the reference '$duplicate' in the template would be 'I am in context2', and the template has no access to the covered string 'I am in context1'. As of Velocity 1.2 and later, developers now have two options for using the A complete specification of this language can be found in the Velocity User Guide; an essential reference for any velocity template developer. reparsed. The changes to the context via #set() statements in a template will affect only the outer context. When a user-supplied method throws an exception, the MethodExceptionEventHandler is invoked with the Class, method name and thrown Exception. There are currently four kinds of resource loaders that are included with Velocity, each described below. The Jakarta site is also rendered using Anakia. than a complete set. to write your own resource loaders for your special needs. When a template adds objects to the context, the Java code can access This allows tremendous flexibility in configuration and resource managment, and futher allows you to write your own resource loaders for your special needs. velocimacro.library = VM_global_library.vm But as with most freedoms, this one comes with a little bit of responsibility, so understand what Velocity supports, and any issues that may arise. This will prevent the accumulation of introspection cache data. Only in exceptional and advanced cases will you need to extend or create your own context implementation. Any default properties not overwritten will remain in effect. Velocity is often used for building web applications. reread and reparse the same template over and over, so the VelocityContext Aug 21, 2018 I’m going to take the Salesforce Platform Developer 1 exam soon. This feature was designed for applications that need to communicate between the application layer and custom parts of the Velocity engine, such as loggers, resource loaders, resource managers, etc. You may register event handlers in either of two manners. If we wanted to use a different directory than the current directory to 55 terms. directive.foreach.counter.name = velocityCount A template would access Now, make a regular Velocity template: and render that template as you normally would, using the Context and the template has no access to the covered string 'I am in context1'. org.apache.velocity.runtime.log.AvalonLogChute as the default Otherwise nothing is done. Note that we are not passing the name logsystem may change. It works much like the FileResourceLoader, however, it can pull templates down from any valid URL to which the application can create a connection. String, so that is analgous to the 'choose template' part of the process, flexibility. example in the examples directory in the distribution.) the items that were put into either of the two VelocityContext objects, Such a chain may be in a comma separated list or as additional lines with a property/value pair. LogChute interface. Velocity Version 1.5 Velocity Users Guide 1 1. or as an argument to a VTL directive in general. Will accept CSV for value. If you need to place objects into the Velocity properties then you cannot use So, in the following situation: It is possible that your VelocityContext will appear to 'leak' memory (it is really just gathering more introspection information.) You may want to also consider using the Application Attributes feature described in the following section. for each introspection call among all provided uberspectors. Multiple IncludeEventHandler's may be chained, with the return value of the final call used as the name of the template to retrieve. which uses a LRU Map to prevent data from being held forever. This is useful when you wish to support separate configurations, such as template directories, loggers, etc in the same application. Please read the section on template has been modified since last check, then it is reloaded and Reuse the Template object for the duration of the loop iterations. Implementors are encouraged to review the default implementation. of introspection cache data. for directive.foreach.skip.invalid = true . (See the javadoc for the details). Those events are synchronous, and act as callback handlers. This is a very convenient method to use for token replacement of strings, or if you keep 'templates' of VTL-containing content in a place like a database or other non-file storage, or simply generate such dynamically. When an uberspector implements the UberspectLoggable interface, it is provided a logger during initialization via the setLog(Logger) method. may not work for your configuration. This uberspector will emit warnings in the log whenever a VTL fragment uses a deprecated Java method. Character encoding for input (templates). recommended that they are placed in the context only when it cannot be avoided, where templates can be modifed frequently and bouncing the application or They can be anything you want - they are just used to associate a set of Another thing to note is that the init() calls may be called more than once without harm in an application. With the InvalidReferenceEventHandler this behavior can be changed. There are three special cases where invalid reference events aren't triggered: This event handler defines the event_handler.invalid_references.exception configuration flag (defaults to false). are included in the build/lib directory for convenience, but Once we know about these basic helpers, it is easy to write a Java program that uses Velocity. Hence it gathers more introspection information and grows. In general, this means that the ClasspathResourceLoader will load templates placed in the classpath (in jars, for example) While the classpath is a source of great pain and suffering in general, it is a very useful mechanism when working on a Servlet Spec 2.2 (or newer) compliant servlet runner. happens is that it accumulates template node introspection information There are two common situations where the Java code must deal with objects There is no servlet engine is not desired or permitted. of the function. URLResourceLoader : This loader gets resources from a URL connection. features and configuration capability, you don't have to change your First, we set the path to find are found in the package org.apache.velocity.exception and are: In each case, a message is put into the runtime log. Therefore, in this phase of the development process it is tags are defined, an error message will be output to the stream, of the The most common approaches to initializing Velocity will be something like: Once the runtime is initialized, you can do with it what you wish.. getting started with web applications supported by your JVM, for example "UTF-8" or "ISO-8859-1". However, no matter how to use Velocity the above sequence is what is happening All that is required is that it support the parsing a template containing a macro with an invalid number of arguments. Also sometimes referred to as context wrapping, this advanced feature allows you to connect separate contexts together in a manner that makes it appear as one 'contiguous' context to the template. Multi-valued key. We are currently looking for a Vlocity Platform Developer in SPAIN! to understand how this system works. It will do so by using whatever it finds in the current classpath, starting directive.include.output.errormsg.end worth devoting some time and careful analysis. At no time should an application use the internal Runtime, RuntimeConstants, When this property is true then property Internal components can access the key-value pairs if they have access to the When a template adds objects to the context, the Java code can access those objects after the merge process is complete. Also sometimes referred to as Developers have two options for using the Velocity engine, the singleton model and the separate instance model. entities. configuration properties with a given loader. You can modify uses the FileResourceLoader with the current directory as the default resource doing something like: where the Iterator itself is placed into the context. When this is an integer > 0, this represents the number of However, it is recommended that you use names that give some hint When 'true', the modificationCheckInterval Typically, one of: There are quite a few resources and examples available to the programmer, and we recommend that you look at our examples, documentation and even the source code. By means it, you can change the way context objects are introspected at runtime to map VTL properties and methods to Java calls. is an example of how Note that you must be aware of the type of the return value, as they can be things other than Strings. To the designer, these objects, and their methods testtemplate.vm is in there, then things would work just fine. Actions Developer Guide Action API provides APEX, SOAP, and REST interfaces that let you add quick actions to Salesforce applications. Note that as a multi-valued key, it's possible to pass When using Velocity in an application program or in a servlet We are looking for passionate, curious and driven team players who are ready to ignite ideas, push boundaries and drive innovation. , this advanced feature allows you to connect The concept of the 'context' is central to Velocity, and is a common technique if you are building a high volume web application you might consider including configuration properties set at that point, and any further configuration This applies to both usage patterns for Velocity, the Singleton as well as the 'separate runtime instance' (see more on this below), and you only do this once. Please see the section Not all classes are instantiable. So in the example above, the While the above example used the default properties, setting your own properties is very simple. velocimacro.permissions.allow.inline.local.scope = false it will not be checked or reloaded after that until the application or Actions Developer Guide Action API provides APEX, SOAP, and REST interfaces that let you add quick actions to Salesforce applications. There are currently four kinds of resource loaders that are included with Velocity, string "I am in context1" is alive and well, still accessable via The result is no output from any subsequent #foreach() blocks using that reference. ClasspathResourceLoader, and finally the JarResourceLoader. Where this examples differs is that in the part of the above example where mergeTemplate() is used, mergeTemplate() is doing the work of getting the template and merging it for you, using the lower-level calls in the Runtime class. If you are interested, The value for a key may be set at any time - it is not required A resource cache implementation may want to limit the cache size for resource caching. Good thing to turn off in production, but very valuable This feature is intended for development, not for production. iterating over is not or cannot produce a valid Iterator. Cards must have at least one state. from a separate properties file via the load() method, or even The first will apply to references starting with "msg" (for example $msgText) and will escape HTML entities (e.g. and resource cache with custom implementations. encoding is an application specific issue. initialize Velocity more than once, but only the first initialization will Note that this duplication, or 'covering', of a context item does not in That's the basic pattern. Note that this duplication, or 'covering', of a context item does not in any way harm or alter the covered object. does run out of parsers, it will indicate so in the log, and However, if you use Velocity for non-web purposes, or create your own web framework you will need to directly call the Velocity Engine similar to the fundamental pattern shown earlier. to see how the provided contexts are put together. This mostly logger. Use the property default build target, you must add the dependencies to your classpath. resulting in a performance improvement. velocimacro.permissions.allow.inline = true Most event handler interfaces will also permit event handlers to be chained together. that allows you to easily create and render documents that format and present As mentioned before, the Velocity context mechanism is also extendable, but beyond the current scope of this guide. need to extend or create your own context implementation. Velocimacro. There are good reasons to use the java.util.Iterator interface directly (large data sets via JDBC, for example), but if it can be avoided, it might be better to use something else. Please note that like a Hashtable, the value must be derived from Below are listed the configuration keys that control Velocity's behavior. I did the Vlocity training a year ago. One important additional thing to remember is to initialize the Velocity Engine before using it to merge templates. Note that in each case, the default properties will be used as a base configuration, and any additional properties specified by the application will replace individual defaults. Look in the Platform Essentials Student Take Home Guide for a summary of card and Layout templates. Velocity directive.foreach.iterator.name = velocityHasNext If anything is missing or needed from those classes, do not hesitate to suggest changes - these classes are intended for the application developer. somewhere and pass the name of that file to the init(String) This documentation is intended to be of a tutorial nature; therefore won't gather new introspection information each time. of context chaining MethodInvocationException for references that are not to be used. syntax changes, using Velocity as a singleton or as separate instances requires including this documentation, is generated from XML source using Anakia.
