All Implemented Interfaces:

TraversableResolver, CachingRelevant

public class CachingTraversableResolver
extends Object
implements TraversableResolver, CachingRelevant

Cache results of a delegated traversable resovler to optimize calls It works only for a single validate* call and should not be used if the TraversableResolver is accessed concurrently
