  org.exolab.castor.xml.schema.ScopableResolver

All Implemented Interfaces:

Resolver

public class ScopableResolver
extends Object
implements Resolver

An implementation of Resolver that can be "scoped". Which means you can construct a ScopableResovler and give it another Resolver (which can also be Scopable). If this Resolver cannot "resolve" the id, then it will try to use the given Resolver to resolver it.
