Enclosing class:

ResourceSetImpl

public abstract static class ResourceSetImpl.ResourceLocator
extends java.lang.Object

A utility class for efficiently locating resources in a resource set. It provides utility methods for delegating to a ResourceSetImpl's protected methods so that derived classes have access to the resource set's full set of protected methods.

Since:

2.8
