Detailed Description

Define the interface for the Queueing Strategy.

The low-level I/O components in the ORB use this strategy to determine when messages must be queued, immediately sent or flushed.

The strategy isolates this low-level components from the higher level strategies used by the application developer.

stub The object used to make the request, this is used to obtain the policies currently in effect for the request
msg_count The number of messages currently queued
total_bytes Number of bytes currently queued
set_timer Returns true if a timer should be set to drain the queue
interval If set_timer returns 1, this parameter contains the timer interval
must_flush Is set to true if things must be flushed at this moment
