18 * Represent the root Java element corresponding to the workspace.
19 * Since there is only one such root element, it is commonly referred to as
20 * <em>the</em> Java model element.
21 * The Java model element needs to be opened before it can be navigated or manipulated.
22 * The Java model element has no parent (it is the root of the Java element
23 * hierarchy). Its children are <code>IJavaProject</code>s.
25 * This interface provides methods for performing copy, move, rename, and
26 * delete operations on multiple Java elements.
29 * This interface is not intended to be implemented by clients. An instance
30 * of one of these handles can be created via
31 * <code>JavaCore.create(workspace.getRoot())</code>.

38 * Returns whether this Java model contains an <code>IJavaElement</code> whose
39 * resource is the given resource or a non-Java resource which is the given resource.

42 * (see <code>IResource.isAccessible()</code>) yet but would be located in Java model
43 * range, then it will return <code>true</code>.
45 * If the resource is accessible, it can be reached by navigating the Java model down using the
46 * <code>getChildren()</code> and/or <code>getNonJavaResources()</code> methods.

57 * elements and containers must match, and each element is copied to
58 * its associated container.
