  com.sun.sgs.impl.kernel.IdentityCoordinatorImpl

All Implemented Interfaces:

IdentityCoordinator

 class IdentityCoordinatorImpl
extends Object
implements IdentityCoordinator

This package-private implementation of IdentityCoordinator is the implementation used by the system when configuring an application. It manages an ordered collection of IdentityAuthenticators. The ordering is used to determine precidence when more than one authenticator can consume the same credentials.

This implementation is kept private to this package so that the context can be assigned, safely, after the coordinator is created. An instance of the coordinator is needed before the context can be created.
