evaluate(self, policies, context)

source code 

Combine the results from evaluating policies or policy sets to make an access control decision. Implementation taken directly from XACML 2.0 spec. pseudo code - Section C.5 First Applicable

Parameters:
  • policies (TypedList(<ndg.xacml.core.policybase.PolicyBase>)) - policies and/or policy sets. Decisions from these will be put together into a single decision by this algorithm.
  • context (ndg.xacml.core.request.Request) - request context to apply to the rules
Returns: ndg.xacml.core.context.result.Decision
resulting overall access control decision
Overrides: PolicyCombiningAlgInterface.evaluate
