Detailed Description

template<ACE_SYNCH_DECL>
class ACE_Message_Queue_Factory<>

ACE_Message_Queue_Factory is a static factory class template which provides a separate factory method for each of the major kinds of priority based message dispatching: static, earliest deadline first (EDF), and minimum laxity first (MLF).

The ACE_Dynamic_Message_Queue class assumes responsibility for releasing the resources of the strategy with which it was constructed: the user of a message queue constructed by any of these factory methods is only responsible for ensuring destruction of the message queue itself.
