Interface POAPolicyMediator

All Known Implementing Classes:

POAPolicyMediatorBase, POAPolicyMediatorBase_R, POAPolicyMediatorImpl_NR_UDS, POAPolicyMediatorImpl_NR_USM, POAPolicyMediatorImpl_R_AOM, POAPolicyMediatorImpl_R_UDS, POAPolicyMediatorImpl_R_USM

public interface POAPolicyMediator

POAPolicyMediator defines an interface to which the POA delegates all policy specific operations. This permits code paths for different policies to be optimized by creating the correct code at POA creation time. Also note that as much as possible, this interface does not do any concurrency control, except as noted. The POA is responsible for concurrency control.
