Class PolicyIntersector

java.lang.Object

org.apache.neethi.util.PolicyIntersector

public class PolicyIntersector
extends java.lang.Object

This class contains methods dealing with policy intersection. Intersection of two assertions, i.e. computation if a compatible assertion, is domain specific and relies on AssertionBuilder.buildCompatible. See Section 4.5 in http://www.w3.org/TR/2006/WD-ws-policy-20061117.
