# TibrvQueueGroup

Class

## Declaration

    class TibrvQueueGroup : public TibrvDispatchable
        TibrvQueueGroup();             // Create empty.
        virtual ~TibrvQueueGroup();    // Destroy and reclaim storage.

## Purpose

Prioritized dispatch of several queues with one call.

## Remarks

Queue groups add flexibility and fine-grained control to the event queue dispatch mechanism. Programs can create groups of queues and dispatch them according to their queue priorities.

The constructor creates a hollow object; TibrvQueueGroup::create() makes it operational.

The destructor calls the `destroy` method, unless the C object is already destroyed.
