org.eclipse.core.resources.mapping.ResourceTraversal
A resource traversal is simply a set of resources and the depth to which each is to be traversed. A set of traversals is used to describe the resources that constitute a model element.
The flags of the traversal indicate which special resources should be included or excluded from the traversal. The flags used are the same as those passed to the {@link IResource#accept(IResourceVisitor,int,int)} method.
This class may be instantiated or subclassed by clients.
