Primary interface for application message processing, as well as input and output message queueing.
Unlike ACE_Task, these class doesn't have the ability to be a part of a Stream chain. I.e. You cannot (yet) chain modules based on ACE_Task_Ex.
Now specialized version of ACE_Task with ACE_Message_Block as its ACE_MESSAGE_TYPE...
template <ACE_SYNCH_DECL> class ACE_Task <ACE_SYNCH_USE, ACE_Message_Block> : public ACE_Task_Base { // put here the good old ACE_Task code };
When User (and legacy code) write ACE_Task<ACE_MT_SYNCH>, specialized ACE_Task code is in action.
typedef ACE_Message_Queue_Ex<ACE_MESSAGE_TYPE, ACE_SYNCH_USE, TIME_POLICY> ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::MESSAGE_QUEUE_EX |

) |
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.
|
virtual |
Destructor.
void ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::dump | ( | void | ) | const |
Dump the state of an object.
|
inline |
Flush the task's queue, i.e., free all of the enqueued message blocks and releases any threads blocked on the queue. Note that if this conflicts with the C++ iostream <flush> function, just rewrite the iostream function as ::<flush>.
|
inline |
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, TIME_POLICY > * ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::module | ( | void | ) | const |
Return the Task's Module if there is one, else returns 0.
ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, ACE_SYNCH_USE, TIME_POLICY > * ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::msg_queue | ( | void | ) |
Gets the message queue associated with this task.
|
inline |
Sets the message queue associated with this task.
const ACE_TCHAR * ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::name | ( | void | ) | const |
Return the name of the enclosing Module if there's one associated with the Task, else returns 0.
|
inline |
Get next Task pointer.
|
inline |
Set next Task pointer.
|
inline |
Transfer message to the adjacent ACE_Task_Ex in a ACE_Stream. Note that timeout uses <{absolute}> time rather than <{relative}> time.
|
inline |
Insert message into the message queue. Note that timeout uses <{absolute}> time rather than <{relative}> time.
|
inline |
Turn the message around and send it back down the Stream. Note that timeout uses <{absolute}> time rather than <{relative}> time.
ACE_Task< ACE_SYNCH_USE, TIME_POLICY > * ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::sibling | ( | void | ) |
|
inline |
Return a message to the queue. Note that timeout uses <{absolute}> time rather than <{relative}> time.
|
inline |
Manipulate watermarks.

ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::ACE_ALLOC_HOOK_DECLARE |
Declare the dynamic allocation hooks.
bool ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::delete_msg_queue_ |
true if should delete Message_Queue, false otherwise.
ACE_Module<ACE_SYNCH_USE, TIME_POLICY>* ACE_Task_Ex< ACE_SYNCH_DECL, ACE_MESSAGE_TYPE, TIME_POLICY >::mod_ |
Back-pointer to the enclosing module.
