Detailed Description

A queue of the messages in the incoming data path.

Please read the documentation in the TAO_Transport class to find out more about the design of the incoming data path.

Under certain conditions TAO may have to maintain a queue per-connection. This queue is drained by the pluggable protocols framework, normally under control of the ACE_Reactor, but other configurations are conceivable.

The memory that is allocated for holding the messages comes from the global pool for the following reasons

• the thread that reads a part of the message would not be the same thread that reads and fills the rest of the message
• the thread that actually processes the message can be totally different.
