Defines the interface for a service that exchanges data with its connected peer and supports buffering.
The buffering feature makes it possible to queue up ACE_Message_Blocks in an ACE_Message_Queue until (1) the queue is "full" or (2) a period of time elapses, at which point the queue is "flushed" via <sendv_n> to the peer.
| ACE_Buffered_Svc_Handler< PR_ST_1, ACE_SYNCH_DECL >::ACE_Buffered_Svc_Handler | ( | ACE_Thread_Manager * | thr_mgr = 0, |
| ACE_Message_Queue< ACE_SYNCH_USE > * | mq = 0, |
||
| ACE_Reactor * | reactor = ACE_Reactor::instance (), |
||
| size_t | max_buffer_size = 0, |
||
| ACE_Time_Value * | relative_timeout = 0 |
||
| ) |
Constructor initializes the thr_mgr and mq by passing them down to the ACE_Task base class. The reactor is passed to the ACE_Event_Handler. The max_buffer_size and relative_timeout are used to determine at what point to flush the mq. By default, there's no buffering at all. The relative_timeout value is interpreted to be in a unit that's relative to the current time returned by <ACE_OS::gettimeofday>.
|
virtual |
Destructor, which calls <flush>.
| void ACE_Buffered_Svc_Handler< PR_ST_1, ACE_SYNCH_DECL >::dump | ( | void | ) | const |
Dump the state of an object.
Reimplemented from ACE_Svc_Handler< ACE_PEER_STREAM_2, ACE_SYNCH_USE >.
|
virtual |
Flush the ACE_Message_Queue, which writes all the queued ACE_Message_Blocks to the <PEER_STREAM>.
|
protectedvirtual |
Implement the flush operation on the ACE_Message_Queue, which writes all the queued ACE_Message_Blocks to the <PEER_STREAM>. Assumes that the caller holds the lock.
|
virtual |
This method is not currently implemented – this is where the integration with the <Reactor> would occur.
Reimplemented from ACE_Svc_Handler< ACE_PEER_STREAM_2, ACE_SYNCH_USE >.
|
virtual |
Insert the ACE_Message_Block chain rooted at message_block into the ACE_Message_Queue with the designated timeout. The <flush> method will be called if this <put> causes the number of bytes to exceed the maximum buffer size or if the timeout period has elapsed.
Reimplemented from ACE_Task_Base.
|
protected |
Current size in bytes of the <Message_Queue> contents.
|
protected |
Interval of the timeout.
|
protected |
Maximum size the <Message_Queue> can be before we have to flush the buffer.
|
protected |
Timeout value used to control when the buffer is flushed.
|
protected |
Timeout pointer.
