The "real" Transport, i.e. the one selected at present. |
Whenever a Transport is selected: during an upcall, or prior to a client invocation an instance of this class is created [on the stack, or as a member of another class] to keep track of the said Transport. The class implements the RAII idiom, which makes it possible to build a stack of these instances as the thread is doing nested upcalls or client invocations.
It utilizes TAO_TSS_Resources::tsg_ member pointer to keep track of stack-linked Transport_Selection_Guard instances.
If the Transport Current feature is disabled most methods are no-ops and add no overhead on the critical path.
