Method Detail

### getPriority

    int getPriority()

  Method which should return the priority level of this message. The messages can range in priority from -15 (highest priority) to 15 (lowest) - when sending messages across the wire, the queue is sorted by message priority. If the queue reaches its limit, the lowest priority messages are discarded. Thus, applications which are very verbose should have LOW_PRIORITY or lower, and applications which are somewhat quiet are allowed to have MEDIUM_PRIORITY or possibly even HIGH_PRIORITY.

  Returns:
    This message's priority
