Interface AlternativeSelector

All Known Implementing Classes:

BaseAlternativeSelector, FirstAlternativeSelector, MaximalAlternativeSelector, MinimalAlternativeSelector

public interface AlternativeSelector

Used by the Policy engine to select the Policy alternative to use. By default, the Policy engine uses a "Minimal" policy alternative selector that finds the alternative with the smallest Collection of Assertions to assert.

selectAlternative

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

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:
