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.

stubThe object used to make the request, this is used to obtain the policies currently in effect for the request
msg_countThe number of messages currently queued
total_bytesNumber of bytes currently queued
set_timerReturns true if a timer should be set to drain the queue
intervalIf set_timer returns 1, this parameter contains the timer interval
must_flushIs set to true if things must be flushed at this moment
