Detailed Description

template<class SVC_HANDLER, ACE_PEER_ACCEPTOR_1>
class ACE_Oneshot_Acceptor< SVC_HANDLER, >

Generic factory for passively connecting clients and creating exactly one service handler (SVC_HANDLER).

This class works similarly to the regular {ACE_Acceptor}, with the following differences: 1. This class doesn't automagically register {this} with the {ACE_Reactor} since it expects to have its {accept} method called directly. However, it stashes the {ACE_Reactor} pointer away in case it's needed later to finish accepting a connection asynchronously. 2. The class doesn't need an {ACE_Creation_Strategy} (since the user supplies the SVC_HANDLER) or an {ACE_Accept_Strategy} (since this class only accepts one connection and then removes all traces of itself from the {ACE_Reactor} if it was registered for asynchronous accepts).

Initialize the appropriate strategies for concurrency and then open the {peer_acceptor} at the designated {local_addr}. Note that unlike the {ACE_Acceptor} and {ACE_Strategy_Acceptor}, this method does NOT register {this} acceptor with the {reactor} at this point -- it just stashes the {reactor} away in case it's needed later.

Bridge method for activating a {svc_handler} with the appropriate concurrency strategy. Default behavior is to activate the {SVC_HANDLER} as a "passive object." However, subclasses can override this strategy to do more sophisticated concurrency activations (such as creating the {SVC_HANDLER} as an "active object" via multi-threading or multi-processing).
