| class | ACE_Module_Type |
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.

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. |

Destructor.

|
|
|
||||||||||
|
Tests whether we can enqueue a message without blocking.
|
|
||||||||||
|
Dump the state of an object.
|
|
||||||||||
|
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>. |
|
||||||||||||||||
|
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. |
|
||||||||||
|
Return the Task's Module if there is one, else returns 0.
|
|
||||||||||
|
Sets the message queue associated with this task.
|
|
||||||||||
|
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. |
|
||||||||||
|
Set next Task pointer.
|
|
||||||||||
|
Get next Task pointer.

|
Transfer message to the adjacent ACE_Task_Ex in a ACE_Stream. Note that <timeout> uses <{absolute}> time rather than <{relative}> time. |
|
||||||||||||||||
|
Insert message into the message queue. Note that <timeout> uses <{absolute}> time rather than <{relative}> time. |
|
||||||||||||||||
|
Turn the message around and send it back down the Stream. Note that <timeout> uses <{absolute}> time rather than <{relative}> time. |
