Detailed Description

template<class SVC_HANDLER>
class ACE_Reactive_Strategy< SVC_HANDLER >

Defines the interface for specifying a reactive concurrency strategy for a SVC_HANDLER, where all upcalls to handle_*() methods run in the reactor's thread of control.

This class provides a strategy that registers the SVC_HANDLER with a <Reactor>.

int ACE_Reactive_Strategy< SVC_HANDLER >::activate_svc_handler	(	SVC_HANDLER *	svc_handler,

Activate the svc_handler by registering it with the <Reactor> and then calling it's <open> hook.
