| <h1 id="Java_Discoverer_API">Java Discoverer API</h1> |
| <p>First, add the following plug-in dependencies to your project ( |
| <b>Require-Bundle</b> in your Manifest.MF): |
| </p> |
| <ul> |
| <li>org.eclipse.modisco.java</li> |
| <li>org.eclipse.modisco.java.discoverer</li> |
| <li>org.eclipse.modisco.infra.discovery.core</li> |
| </ul> |
| <p>There are several Java discoverer classes that do the same discovery but on different inputs:</p> |
| <ul> |
| <li>DiscoverJavaModelFromJavaProject : from an IJavaProject (defined in jdt.core)</li> |
| <li>DiscoverJavaModelFromProject : from an IProject</li> |
| <li>DiscoverJavaModelFromClassFile : from an IClassFile (defined in jdt.core)</li> |
| <li>DiscoverJavaModelFromLibrary : from an IPackageFragmentRoot (for jars; defined in jdt.core)</li> |
| </ul> |
| <p>You can easily discover a Java model programmatically. For example, to discover a Java model from a Java project:</p> |
| <pre> |
| DiscoverJavaModelFromJavaProject discoverer = new DiscoverJavaModelFromJavaProject(); |
| javaDiscoverer.discoverElement(javaProject, monitor); |
| Resource javaResource = javaDiscoverer.getTargetModel(); |
| </pre> |
| <p>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.</p> |
| <p>Once you have the Java Resource, you can use the standard EMF API to read model elements. For example, to get the root:</p> |
| <pre> |
| Model javaModel = (Model) javaResource.getContents().get(0); |
| </pre> |
| <p>To print the list of Java classes in the model:</p> |
| <pre> |
| EList<ClassFile> classFiles = javaModel.getClassFiles(); |
| for (ClassFile classFile : classFiles) { |
| System.out.println(classFile.getName()); |
| } |
| </pre> |
| </body> |
| </html> |
