          com.sun.xacml.combine.DenyOverridesPolicyAlg

Direct Known Subclasses:

OrderedDenyOverridesPolicyAlg

public class DenyOverridesPolicyAlg

extends PolicyCombiningAlgorithm

This is the standard Deny Overrides policy combining algorithm. It allows a single evaluation of Deny to take precedence over any number of permit, not applicable or indeterminate results. Note that since this implementation does an ordered evaluation, this class also supports the Ordered Deny Overrides algorithm.

Since:
