| <em>The following description is copied from org.eclipse.emf.importer.rose, which |
| this plug-in almost duplicates. See <a href="installation.html">Installation</a> |
| for specific instructions on getting this plug-in and its dependents to install and build. |
| </em> |
| <h3>Introduction</h3> |
| <p>Usage of the QVT Rose UML importer is almost identical to the standard EMF Rose usage. The differences is that the |
| RoseUML conversions apply a UML interpreation to Association Role Constraints such as {ordered}. |
| The normal Rose conversion ignores these constraints and consequently treats all associations as ordered.</p> |
| <p>This document describes how you can use scripts to generate code from a Rose UML model. The |
| script can be either a regular shell script that invokes <a href="#headlessApplication">Eclipse headless |
| applications</a> or an Ant script that invokes the <a href="#antTasks">task</a> provided by this plugin.</p> |
| |
| <h3><a name="overallComments">Overall Comments</a></h3> |
| <ul> |
| <li>If you didn't extract this plugin from CVS, the "examples" directory mentioned |
| in this document is available in the EMF source plugin |
| (org.eclipse.emf.source_<i><version></i>/src/org.eclipse.emf.importer.rose_<i><version></i>). |
| <br/><br/></li> |
| <li>Before running your build scripts or the examples provided here, make sure you have the 2 |
| jar files required by this plugin ("importer.roseuml.jar" and |
| "importer.roseuml.tasks.jar") and also the 2 jar files required by the <tt>org.eclipse.emf.ant</tt> |
| plugin ("emf.ant.jar" and "emf.ant.tasks.jar"). If necessary, Eclipse |
| can generate them for you. All you need to do is to run the Ant script created by PDE when you right click on the manifest file |
| and select "PDE Tools>Create Ant Build File". |
| <br/><br/></li> |
| <li>Although the applications and task mentioned here must be executed by Eclipse (usually in headless mode), they can |
| work on files located in any directory. In other words, your models, templates and other files don't need |
| to be in the "plugins" directory nor in the workspace. |
| <br/><br/></li> |
| <li>In order to preserve the original state of this plugin's "examples" directory, you |
| should copy it to a different location and run the Ant scripts from there. |
| <br/><br/></li> |
| <li>Starting a new JVM process and invoking Eclipse are expensive operations. Your build will |
| perform better if you are able to group the steps that require Eclipse in a few scripts |
| (one script would be ideal). This is probably a reason to use Ant instead of invoking the |
| applications - you can generate code for multiple models using one single Ant script. |
| <br/><br/></li> |
| <li>The "examples/library" directory contains a Rose model, and shell and Ant scripts |
| to generate its code. |
| </li> |
| </ul> |
| |
| <h3><a name="headlessApplication">Rose and Generator Applications</a></h3> |
| <p>The application provided by this plugin generates the ecore and genmodel files from models defined |
| using Rose.</p> |
| <table border="1" cellpadding="2" cellspacing="0" |
| summary="Lists the details about the Rose application."> |
| <tr><td colspan="2">Rose application details</td></tr> |
| <tr><td>ID</td><td><tt>org.eclipse.emf.importer.roseuml.RoseUML2GenModel</tt></td></tr> |
| <tr><td>Class</td><td><tt>org.eclipse.emf.importer.roseuml.RoseUMLImporterApplication</tt></td></tr> |
| </table> |
| <p>To generate the actual Java code you will need to use a second application, provided by |
| the "org.eclipse.emf.codegen.ecore" plugin.</p> |
| <table border="1" cellpadding="2" cellspacing="0" |
| summary="Lists the details about the Generator application."> |
| <tr><td colspan="2">Generator application details</td></tr> |
| <tr><td>ID</td><td><tt>org.eclipse.emf.codegen.ecore.Generator</tt></td></tr> |
| <tr><td>Class</td><td><tt>org.eclipse.emf.codegen.ecore.Generator</tt></td></tr> |
| </table> |
| <p>In order to run these or any other Eclipse application, you need to execute the following |
| command (without the line breaks):</p> |
| <p> |
| java |
| <br/> -classpath <i><eclipseDir></i>/startup.jar org.eclipse.core.launcher.Main |
| <br/> -data <i><full path to a workspace - ideally an empty directory></i> |
| <br/> -application <i><application ID></i> |
| <br/> <i><application arguments></i> |
| </p> |
| <p>The directory "examples/library/build" has shell scripts that generate the code for |
| the model provided. If you have any questions after reading and experimenting with it, look at the |
| applications's javadoc for more details. Also, check the application's class |
| "getUsage()" method for the list of possible arguments.</p> |
| |
| <h3><a name="antTasks">Rose Ant Task</a></h3> |
| <p>The Rose task details are:</p> |
| <table border="1" cellpadding="2" cellspacing="0" |
| summary="Lists the details about the Rose task."> |
| <tr><td>Name</td><td><tt>emf.Rose2Java</tt></td></tr> |
| <tr><td>Class</td><td><tt>org.eclipse.emf.importer.roseuml.taskdefs.RoseUMLGeneratorTask</tt></td></tr> |
| </table> |
| <p>This is the usual command line to run an Ant script using a headless Eclipse instance (remove the line breaks):</p> |
| <p> |
| java |
| <br/> -classpath <i><eclipseDir></i>/startup.jar org.eclipse.core.launcher.Main |
| <br/> -data <i><full path to a workspace - ideally an empty directory></i> |
| <br/> -application org.eclipse.ant.core.antRunner |
| <br/> -buildfile <i><full path to your script></i> |
| </p> |
| <p>The directory "examples/library/build" has an Ant script that generate the code for |
| the model provided. The task's javadoc has lots of information you may find useful.</p> |
