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>.
