Detailed Description

Defines the interface for policy-based endpoint selection strategies.

Selects/reselects server endpoint for an Invocation. Different concrete strategies perform selection based on different policies. All endpoint selection strategies are stateless objects - any necessary state is stored in Invocation's <endpoint_selection_state_>.

Member Function Documentation

virtual void TAO_Invocation_Endpoint_Selector::close_connection (  TAO_GIOP_Invocation *    invocation )  [pure virtual]

Update the state to reflect that the connection being used for the invocation has been closed by the server. Reimplemented in TAO_Default_Endpoint_Selector.

virtual void TAO_Invocation_Endpoint_Selector::forward (  TAO_GIOP_Invocation *    invocation, const TAO_MProfile &mprofile    ACE_ENV_ARG_DECL )  [pure virtual]

This method must be called if the invocation attempt on a selected endpoint resulted in location forward. This method performs the necessary state updates, so that next <select_endpoint> call picks a new endpoint. Reimplemented in TAO_Default_Endpoint_Selector.

virtual void TAO_Invocation_Endpoint_Selector::select_endpoint (  TAO_GIOP_Invocation *invocation    ACE_ENV_ARG_DECL )  [pure virtual]

Select the endpoint and set <invocation>'s <profile_> and <endpoint_> data members accordingly. Reimplemented in TAO_Default_Endpoint_Selector.

virtual void TAO_Invocation_Endpoint_Selector::success (  TAO_GIOP_Invocation *    invocation )  [pure virtual]

Update the state to indicate that the selected endpoint/profile were used successfully. Reimplemented in TAO_Default_Endpoint_Selector.
