+ * @class TAO_Default_Endpoint_Selector_Factory
+ *
+ * @brief Factory for initializing <Endpoint_Selection_State> and
+ * obtaining appropriate <Invocation_Endpoint_Selector>.
+ *
+ * Used by Invocation classes to intialize 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.
