evaluate(self, rules, context)

source code

Combine the input rule results to make an access control decision. Implementation taken direct from XACML 2.0 spec. pseudo code - Section C.5

Parameters:

rules (TypedList(<ndg.xacml.core.rule.Rule>)) - rules from the policy. 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: RuleCombiningAlgInterface.evaluate
