Detailed Description

template<class SVC_HANDLER> template class ACE_Process_Strategy

Defines the interface for specifying a concurrency strategy for a <SVC_HANDLER> based on multiprocessing.

This class provides a strategy that manages the creation of processes to handle requests from clients concurrently. It behaves as a "process factory", using to fork threads "on-demand" to run the service specified by a user-supplied <SVC_HANDLER> in a separate process.

Member Function Documentation

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

Activate the <svc_handler> with an appropriate concurrency strategy. This method activates the SVC_HANDLER by first forking and then calling the <open> method of the SVC_HANDLER in the child.

Reimplemented from ACE_Concurrency_Strategy.

template<classSVC_HANDLER>
void ACE_Process_Strategy<SVC_HANDLER>::dump ( void ) const
 

Dump the state of an object.

Reimplemented from ACE_Concurrency_Strategy.

template<classSVC_HANDLER>
int ACE_Process_Strategy<SVC_HANDLER>::open ( size_t n_processes = 1,
ACE_Event_Handler * acceptor = 0,
ACE_Reactor * reactor = 0,
int avoid_zombies = 0 ) [virtual]
 

Initialize the strategy. If is non-0 then set a flag to to avoid zombies.

This is the in the parent is listening on. We need to make sure that we remove it from the Reactor and close it down in the child.

template<classSVC_HANDLER>
size_t ACE_Process_Strategy<SVC_HANDLER>::n_processes_ [protected]
 

Number of processes to spawn.

This is the <Reactor> the child is using in conjunction with the . We need to remove the from this <Reactor> in the child.
