org.eclipse.core.resources.IResourceProxy

A lightweight interface for requesting information about a resource. All of the "get" methods on a resource proxy have trivial performance cost. Requesting the full path or the actual resource handle will cause extra objects to be created and will thus have greater cost.

When a resource proxy is used within an {@link IResourceProxyVisitor}, it is a transient object that is only valid for the duration of a single visit method. A proxy should not be referenced once the single resource visit is complete. The equals and hashCode methods should not be relied on.

A proxy can also be created using {@link IResource#createProxy()}. In this case the proxy is valid indefinitely, but will not remain in sync with the state of the corresponding resource.

This interface is not intended to be implemented by clients.
