Detailed Description

Base class for all the Thread_Adapters.

Converts a C++ function into a function that can be called from a thread creation routine (e.g., pthread_create() or _beginthreadex()) that expects an extern "C" entry point. This class also makes it possible to transparently provide hooks to register a thread with an ACE_Thread_Manager. This class is used in ACE_OS::thr_create(). In general, the thread that creates an object of this class is different from the thread that calls invoke() on this object. Therefore, the invoke() method is responsible for deleting itself.

Member Function Documentation

void ACE_Base_Thread_Adapter::close_log_msg ( void  ) [static]

Invoke the close_log_msg_hook, if it is present.

ACE_THR_C_FUNC ACE_Base_Thread_Adapter::entry_point ( void  ) [inline]

Accessor for the C entry point function to the OS thread creation routine.

void ACE_Base_Thread_Adapter::inherit_log_msg ( void  ) [protected]

Inherit the logging features if the parent thread has an ACE_Log_Msg.

virtual ACE_THR_FUNC_RETURN ACE_Base_Thread_Adapter::invoke ( void  ) [pure virtual]

Virtual method invoked by the thread entry point.

Implemented in ACE_Thread_Adapter, and ACE_OS_Thread_Adapter.

void ACE_Base_Thread_Adapter::set_log_msg_hooks ( ACE_INIT_LOG_MSG_HOOK  init_hook,
ACE_INHERIT_LOG_MSG_HOOK  inherit_hook,
ACE_CLOSE_LOG_MSG_HOOK  close_hook,
ACE_SYNC_LOG_MSG_HOOK  sync_hook,
ACE_THR_DESC_LOG_MSG_HOOK  thr_desc 
) [inline, static, private]

Set the Log_Msg hooks.

void ACE_Base_Thread_Adapter::sync_log_msg ( const ACE_TCHAR prog_name) [static]

Invoke the sync_log_msg_hook, if it is present.

ACE_OS_Thread_Descriptor * ACE_Base_Thread_Adapter::thr_desc_log_msg ( void  ) [static]

Invoke the thr_desc_log_msg_hook, if it is present.

Member Data Documentation

void* ACE_Base_Thread_Adapter::arg_ [protected]

Argument to thread startup function.

That is useful for gprof, define itimerval.

Keep a reference to the configuration context that spawns the thread so the child can inherit it.

ACE_THR_C_FUNC ACE_Base_Thread_Adapter::entry_point_ [protected]

Entry point to the underlying OS thread creation call (C linkage).

Pass through the thread-creation flags that can only be acted on by the spawned thread. Currently this is only the cancellation-related flags.

The hooks to inherit and cleanup the Log_Msg attributes.

The ACE_Log_Msg attributes.

Optional thread descriptor. Passing this pointer in will force the spawned thread to cache this location in Log_Msg and wait until Thread_Manager fills in all information in thread descriptor.

ACE_THR_FUNC ACE_Base_Thread_Adapter::user_func_ [protected]

Thread startup function passed in by the user (C++ linkage).
