Enqueue and dequeue methods
The enqueue and dequeue methods accept a timeout value passed as an ACE_Time_Value *. In all cases, if the timeout pointer is 0, the caller will block until action is possible. If the timeout pointer is non-zero, the call will wait (if needed, subject to water mark settings) until the absolute time specified in the referenced ACE_Time_Value object is reached. If the time is reached before the desired action is possible, the method will return -1 with errno set to EWOULDBLOCK. Regardless of the timeout setting, however, these methods will also fail and return -1 when the queue is closed, deactivated, pulsed, or when a signal occurs.

The time parameters are handled the same as in ACE_Message_Queue, so you can see C++NPv2 Section 6.2 and APG Section 12.3 for a fuller treatment of ACE_Message_Queue, enqueueing, dequeueing, and how these operations are affected by queue state transitions.

Detailed Description

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL>
class ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >

A threaded message queueing facility, modeled after the queueing facilities in System V STREAMs.

ACE_Message_Queue_Ex is a strongly-typed version of the ACE_Message_Queue class. Rather than queueing in terms of ACE_Message_Block objects, ACE_Message_Queue_Ex has a template argument to specify the type of objects that are queued.

The second template argument parameterizes the queue's synchronization. The argument specifies a synchronization strategy. The two main strategies available for ACE_SYNCH_DECL are:

  1. ACE_MT_SYNCH: all operations are thread-safe
  2. ACE_NULL_SYNCH: no synchronization and no locking overhead

Member Enumeration Documentation

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
anonymous enum
 

Enumeration values:
DEFAULT_PRIORITY  Default priority value. This is the lowest priority.

Definition at line 968 of file Message_Queue_T.h. 

00969   {
00970     /// Default priority value. This is the lowest priority.
00971     DEFAULT_PRIORITY = 0
00972   };

Constructor & Destructor Documentation

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::ACE_Message_Queue_Ex (  size_t  high_water_mark = ACE_Message_Queue_Base::DEFAULT_HWM,
size_t  low_water_mark = ACE_Message_Queue_Base::DEFAULT_LWM,
ACE_Notification_Strategy *  ns = 0
) 
 

Initialize an ACE_Message_Queue_Ex.

Parameters:
high_water_mark High water mark. Determines how many bytes can be stored in a queue before it's considered full. Supplier threads must block until the queue is no longer full.
low_water_mark Low water mark. Determines how many bytes must be in the queue before supplier threads are allowed to enqueue additional data. By default, the hwm equals lwm, which means that suppliers will be able to enqueue new messages as soon as a consumer removes any message from the queue. Making the low water mark smaller than the high water mark forces consumers to drain more messages from the queue before suppliers can enqueue new messages, which can minimize the "silly window syndrome."
ns Notification strategy. Pointer to an object conforming to the ACE_Notification_Strategy interface. If set, the object's notify(void) method will be called each time data is added to this ACE_Message_Queue.

ACE_Reactor_Notification_Strategy.

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::~ACE_Message_Queue_Ex (  void   )  [virtual]
 

Releases all resources from the message queue and marks it deactivated.

Member Function Documentation

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::activate (  void   )  [virtual]
 

Reactivate the queue so that threads can enqueue and dequeue messages again. Returns the state of the queue before the call.

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::close (  void   )  [virtual]
 

Releases all resources from the message queue and marks it deactivated.

See also:
flush().
Return values:
The number of messages released from the queue; -1 on error.

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::deactivate (  void   )  [virtual]
 

Deactivate the queue and wakeup all threads waiting on the queue so they can continue. No messages are removed from the queue, however. Any other operations called until the queue is activated again will immediately return -1 with errno == ESHUTDOWN. Returns WAS_INACTIVE if queue was inactive before the call and WAS_ACTIVE if queue was active before the call.

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::deactivated (  void   )  [virtual]
 

Returns true if the state of the queue is DEACTIVATED, but false if the queue's state is ACTIVATED or PULSED.

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::dequeue (  ACE_MESSAGE_TYPE *&  first_item,
ACE_Time_Value *  timeout = 0
)  [virtual]
 

This method is an alias for the following method.

virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::dequeue_deadline (  ACE_MESSAGE_TYPE *&  dequeued,
ACE_Time_Value *  timeout = 0
)  [virtual]
 

Because there's deadline associated with enqueue_deadline(), this method will behave just as dequeue_head().

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::dequeue_head (  ACE_MESSAGE_TYPE *&  first_item,
ACE_Time_Value *  timeout = 0

timeout The absolute time the caller will wait until for an item to be dequeued.
Return values:
>=0 The number of items remaining in the queue.
-1 On failure. errno holds the reason. Common errno values are:
  • EWOULDBLOCK: the timeout elapsed
  • ESHUTDOWN: the queue was deactivated or pulsed

virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::dequeue_tail (  ACE_MESSAGE_TYPE *&  dequeued,
ACE_Time_Value *  timeout = 0
)  [virtual]
 

Dequeue the item at the tail of the queue and return a pointer to it.

Parameters:
dequeued Reference to an ACE_MESSAGE_TYPE * that will be set to the address of the dequeued item.
timeout The absolute time the caller will wait until for an item to be dequeued.
Return values:
>=0 The number of items remaining in the queue.

virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::enqueue_deadline (  ACE_MESSAGE_TYPE *  new_item,
ACE_Time_Value *  timeout = 0
)  [virtual]
 

This method acts just like enqueue_tail(). There's no deadline time associated with items.

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >

)  [virtual]
 

Retrieve a pointer to the first item in the queue without removing it.

Note:
Because the item whose pointer is returned is still on the queue, another thread may dequeue that item at any time, including before the calling thread examines the peeked-at item. Be very careful with this method in multithreaded queueing situations.
Parameters:
first_item Reference to an ACE_MESSAGE_TYPE * that will point to the first item on the queue. The item remains on the queue until this or another thread dequeues it.
timeout The absolute time the caller will wait until for an item to be queued.
Return values:
>0 The number of items on the queue.
-1 On failure. errno holds the reason. Common errno values are:
  • EWOULDBLOCK: the timeout elapsed
  • ESHUTDOWN: the queue was deactivated or pulsed

template<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL >
virtual int ACE_Message_Queue_Ex< ACE_MESSAGE_TYPE, >::pulse (  void   )  [virtual]
