Detailed Description

template<class SVC_HANDLER>
class ACE_Concurrency_Strategy< SVC_HANDLER >

Defines the interface for specifying a concurrency strategy for a SVC_HANDLER.

Default behavior is to activate the SVC_HANDLER by calling its <open> method (which allows the SVC_HANDLER to define its own concurrency strategy). However, subclasses can override this default strategy to do more sophisticated concurrency activations (such as creating the SVC_HANDLER as an active object via multi-threading or multi-processing).

template<class SVC_HANDLER >

int ACE_Concurrency_Strategy< SVC_HANDLER >::activate_svc_handler	(	SVC_HANDLER *	svc_handler,
		void *	arg = 0
	)			[virtual]

Activate the svc_handler with an appropriate concurrency strategy. The default behavior of this method is to activate the SVC_HANDLER by calling its <open> method (which allows the SVC_HANDLER to define its own concurrency strategy).

Reimplemented in ACE_Reactive_Strategy< SVC_HANDLER >, ACE_Thread_Strategy< SVC_HANDLER >, ACE_Process_Strategy< SVC_HANDLER >, and ACE_NOOP_Concurrency_Strategy< SVC_HANDLER >.
