@ThreadSafe
public final class AttributeFilterPolicy
extends AbstractIdentifiedInitializableComponent
implements UnmodifiableComponent

A policy describing if a set of attribute value filters is applicable. Note, this filter policy operates on the AttributeFilterContext.getFilteredIdPAttributes() attribute set. The idea being that as policies run they will retain or remove attributes and values for this collection. After all policies run this collection will contain the final result.
