Represents a node in the queue of incoming messages.
This class contains necessary information about a message that is stored in the queue. Such a node can be used by the incoming thread from the reactor to dequeue and process the message by sending it to the higher layers of the ORB.
The ACE_Message_Block contained within this class may contain a chain of message blocks (usually when GIOP fragments are involved). In that case consolidate () needs to be called prior to being sent to higher layers of the ORB when the GIOP fragment chain is complete.
