| = Java Discoverer API = | |
| First, add the following plug-in dependencies to your project ('''Require-Bundle''' in your Manifest.MF): | |
| * org.eclipse.modisco.java | |
| * org.eclipse.modisco.java.discoverer | |
| * org.eclipse.modisco.infra.discovery.core | |
| There are several Java discoverer classes that do the same discovery but on different inputs: | |
| * DiscoverJavaModelFromJavaProject : from an IJavaProject (defined in jdt.core) | |
| * DiscoverJavaModelFromProject : from an IProject | |
| * DiscoverJavaModelFromClassFile : from an IClassFile (defined in jdt.core) | |
| * DiscoverJavaModelFromLibrary : from an IPackageFragmentRoot (for jars; defined in jdt.core) | |
| You can easily discover a Java model programmatically. For example, to discover a Java model from a Java project: | |
| <pre> | |
| DiscoverJavaModelFromJavaProject discoverer = new DiscoverJavaModelFromJavaProject(); | |
| javaDiscoverer.discoverElement(javaProject, monitor); | |
| Resource javaResource = javaDiscoverer.getTargetModel(); | |
| </pre> | |
| To have a monitor to pass to the <code>discoverElement</code> method, you can either call the discoverer in an Eclipse Job, or pass a new NullProgressMonitor if you don't need progress reporting. | |
| Once you have the Java Resource, you can use the standard EMF API to read model elements. For example, to get the root: | |
| <pre> | |
| Model javaModel = (Model) javaResource.getContents().get(0); | |
| </pre> | |
| To print the list of Java classes in the model: | |
| <pre> | |
| EList<ClassFile> classFiles = javaModel.getClassFiles(); | |
| for (ClassFile classFile : classFiles) { | |
| System.out.println(classFile.getName()); | |
| } | |
| </pre> |
