- 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:
- 1.0
