class | ACE_Module< ACE_SYNCH_USE > |
class | ACE_Module_Type |
This class serves as the basis for passive and active objects in ACE.
ACE_Task<>::ACE_Task | ( | ACE_Thread_Manager * | thr_mgr = 0 , |
|
ACE_Message_Queue< ACE_SYNCH_USE > * | mq = 0 | |||
) |
Initialize a Task, supplying a thread manager and a message queue. If the user doesn't supply a ACE_Message_Queue pointer then we'll allocate one dynamically. Otherwise, we'll use the one passed as a parameter.
int ACE_Task<>::can_put | ( | ACE_Message_Block * | ) |
Tests whether we can enqueue a message without blocking.
void ACE_Task<>::dump | ( | void | ) | const |
Dump the state of an object.
Reimplemented in ACE_Stream_Head<>, ACE_Stream_Tail<>, ACE_Thru_Task<>, ACE_Svc_Handler<, >, ACE_Buffered_Svc_Handler<, >, and ACE_Svc_Handler< ACE_PEER_STREAM_2, ACE_SYNCH_USE >.
int ACE_Task<>::flush | ( | u_long | flag = ACE_Task_Flags::ACE_FLUSHALL |
) |
Flush the task's queue, i.e., free all of the enqueued message blocks and unblocks any threads waiting on the queue. Note that if this conflicts with the C++ iostream <flush> function, just rewrite the iostream function as ::<flush>.
int ACE_Task<>::getq | ( | ACE_Message_Block *& | mb, | |
ACE_Time_Value * | timeout = 0 | |||
) |
Extract the first message from the queue (blocking). Note that <timeout> uses <{absolute}> time rather than <{relative}> time. Returns number of items in queue if the call succeeds or -1 otherwise.
ACE_Module<ACE_SYNCH_USE>* ACE_Task<>::module | ( | void | ) | const |
Return the Task's Module if there is one, else returns 0.
void ACE_Task<>::msg_queue | ( | ACE_Message_Queue< ACE_SYNCH_USE > * | ) |
Sets the message queue associated with this task.
ACE_Message_Queue<ACE_SYNCH_USE>* ACE_Task<>::msg_queue | ( | void | ) |
Gets the message queue associated with this task.
Return the name of the enclosing Module if there's one associated with the Task, else returns 0.
Reimplemented in ACE_NT_Service.
Set next Task pointer.
int ACE_Task<>::put_next | ( | ACE_Message_Block * | msg, | |
ACE_Time_Value * | timeout = 0 | |||
) |
Transfer message to the adjacent ACE_Task in a ACE_Stream. Note that <timeout> uses <{absolute}> time rather than <{relative}> time.
int ACE_Task<>::putq | ( | ACE_Message_Block * | , | |
ACE_Time_Value * | timeout = 0 | |||
) |
Insert message into the message queue. Note that <timeout> uses <{absolute}> time rather than <{relative}> time.
int ACE_Task<>::reply | ( | ACE_Message_Block * | , | |
ACE_Time_Value * | timeout = 0 | |||
) |
Turn the message around and send it back down the Stream. Note that <timeout> uses <{absolute}> time rather than <{relative}> time.
Return the Task's sibling if there's one associated with the Task's Module, else returns 0.
int ACE_Task<>::ungetq | ( | ACE_Message_Block * | , | |
ACE_Time_Value * | timeout = 0 | |||
) |
Return a message to the queue. Note that <timeout> uses <{absolute}> time rather than <{relative}> time.
void ACE_Task<>::water_marks | ( | ACE_IO_Cntl_Msg::ACE_IO_Cntl_Cmds | , | |
size_t | ||||
) |
Manipulate watermarks.

ACE_Task<>::ACE_ALLOC_HOOK_DECLARE |
Declare the dynamic allocation hooks.
Reimplemented in ACE_NT_Service, ACE_Stream_Head<>, ACE_Stream_Tail<>, and ACE_Thru_Task<>.
int ACE_Task<>::delete_msg_queue_ |
1 if should delete Message_Queue, 0 otherwise.
ACE_Module<ACE_SYNCH_USE>* ACE_Task<>::mod_ |
Back-pointer to the enclosing module.
ACE_Message_Queue<ACE_SYNCH_USE>* ACE_Task<>::msg_queue_ |
Queue of messages on the ACE_Task..
