Method Detail

evaluate

public ResponseCtx evaluate(RequestCtx request)
                     throws java.lang.Exception

Attempts to evaluate the request against the policies known to this PDP. This is really the core method of the entire XACML specification, and for most people will provide what you want. If you need any special handling, you should look at the version of this method that takes an EvaluationCtx.

Note that if the request is somehow invalid (it was missing a required attribute, it was using an unsupported scope, etc), then the result will be a decision of INDETERMINATE.

Parameters:

request - the request to evaluate

Returns:

a response paired to the request

Throws:

java.lang.Exception
