org.eclipse.core.resources.mapping.ResourceMapping
A resource mapping supports the transformation of an application model object into its underlying file system resources. It provides the bridge between a logical element and the physical resource(s) into which it is stored but does not provide more comprehensive model access or manipulations.
Mappings provide two means of model traversal. The {@link #accept} methodcan be used to visit the resources that constitute the model object. Alternatively, a set or traversals can be obtained by calling {@link #getTraversals}. A traversal contains a set of resources and a depth. This allows clients (such a repository providers) to do optimal traversals of the resources w.r.t. the operation that is being performed on the model object.

This class may be subclassed by clients.
