Detailed Description

template<class SVC_HANDLER, ACE_PEER_ACCEPTOR_1> template class ACE_Strategy_Acceptor

Abstract factory for creating a service handler (SVC_HANDLER), accepting into the SVC_HANDLER, and activating the SVC_HANDLER.

Implements a flexible and extensible set of strategies for passively establishing connections with clients. There are three main strategies: (1) creating a SVC_HANDLER, (2) passively accepting a new connection from a client into the SVC_HANDLER, and (3) activating the SVC_HANDLER with a particular concurrency mechanism.

Member Function Documentation

template<classSVC_HANDLER, ACE_PEER_ACCEPTOR_1>
int ACE_Strategy_Acceptor<SVC_HANDLER, >::accept_svc_handler ( SVC_HANDLER * svc_handler ) [protected, virtual]
 

Bridge method for accepting the new connection into the <SVC_HANDLER>. The default behavior delegates to the <PEER_ACCEPTOR::accept> in the .

Reimplemented from ACE_Acceptor.

template<classSVC_HANDLER, ACE_PEER_ACCEPTOR_1>
ACE_PEER_ACCEPTOR & ACE_Strategy_Acceptor<SVC_HANDLER, >::acceptor ( void ) const [virtual]
 

Return the underlying PEER_ACCEPTOR object.

Reimplemented from ACE_Acceptor.

template<classSVC_HANDLER, ACE_PEER_ACCEPTOR_1>
int ACE_Strategy_Acceptor<SVC_HANDLER, >::activate_svc_handler ( SVC_HANDLER * svc_handler ) [protected, virtual]
 

Bridge method for activating a <SVC_HANDLER> with the 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). 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).

Reimplemented from ACE_Acceptor.

template<classSVC_HANDLER, ACE_PEER_ACCEPTOR_1>
void ACE_Strategy_Acceptor<SVC_HANDLER, >::dump ( void ) const
 

Dump the state of an object.

Reimplemented from ACE_Acceptor.

template<classSVC_HANDLER, ACE_PEER_ACCEPTOR_1>
int ACE_Strategy_Acceptor<SVC_HANDLER, >::fini ( void ) [protected, virtual]
 

Calls <handle_close> when dynamically unlinked.

Reimplemented from ACE_Acceptor.

template<classSVC_HANDLER, ACE_PEER_ACCEPTOR_1>
int ACE_Strategy_Acceptor<SVC_HANDLER, >::make_svc_handler ( SVC_HANDLER *& sh ) [protected, virtual]
 

Bridge method for creating a <SVC_HANDLER>. The strategy for creating a <SVC_HANDLER> are configured into the Acceptor via it's <creation_strategy_>. The default is to create a new <SVC_HANDLER> if <sh> == 0, else <sh> is unchanged. However, subclasses can override this policy to perform <SVC_HANDLER> creation in any way that they like (such as creating subclass instances of <SVC_HANDLER>, using a singleton, dynamically linking the handler, etc.). Returns -1 on failure, else 0.

Reimplemented from ACE_Acceptor.
