com.sun.xacml.combine
Class PermitOverridesPolicyAlg  

java.lang.Object
  com.sun.xacml.combine.CombiningAlgorithm
      com.sun.xacml.combine.PolicyCombiningAlgorithm
          com.sun.xacml.combine.PermitOverridesPolicyAlg

Direct Known Subclasses:

OrderedPermitOverridesPolicyAlg

---

public class PermitOverridesPolicyAlg

extends PolicyCombiningAlgorithm

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

Since:

1.0
