                     throws EnforcerInstantiationException

getInstance in interface EnforcerFactory

Parameters:

actionType - The String specifying the action type, for which an enforcer is requested.

initPlatformContext - Not needed in this implementation.

initAgentContext - A hashtable containing the GUID of the agent associated with the requested Enforcer.

Returns:

Enforcer an instance of the requested enforcer type.

Throws:
