* @brief 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.
