Detailed Description

Factory for initializing <Endpoint_Selection_State> and obtaining appropriate <Invocation_Endpoint_Selector>.

Used by Invocation classes to initialize its endpoint selection strategy and state based on the effective policies. Endpoint selection strategies are stateless objects - all the state they need is contained by Invocation in <Endpoint_Selection_State>. Thus, rather than allocating an endpoint selection strategy object for each Invocation, the factory simply returns the appropriate one from the set preallocated in the ORB_Core. One endpoint selection strategy object can be used by many invocations concurrently.
