selectAlternative

Collection<org.apache.neethi.Assertion> selectAlternative(org.apache.neethi.Policy policy,
                                                        PolicyEngine engine,
                                                        Assertor assertor,
                                                        List<List<org.apache.neethi.Assertion>> request,

Parameters:: policy - The full policy to consider; engine - The policy engine calling the selector; assertor - Additional asserter (such as the transport) that may be able to handle some of the assertions; request - On the server out bound side, this will contain the alternatives from the request that were successfully met by the request. The selector should use these to help narrow down the alternative to use.
Returns:
