org.wso2.balana.combine.xacml3.PermitOverridesRuleAlg

Direct Known Subclasses:

OrderedPermitOverridesRuleAlg

public class PermitOverridesRuleAlg
extends RuleCombiningAlgorithm

This is the new (XACML 3.0) the standard Permit Overrides rule 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.
