Detailed Description

template<class TQ, class TYPE = ACE_Event_Handler*>
class ACE_Thread_Timer_Queue_Adapter< TQ, TYPE >

Adapts an ACE timer queue using a separate thread for dispatching.

This implementation uses a separate thread to dispatch the timers. The base queue need not be thread safe; this class takes all the necessary locks.

Note: This is a case where template parameters will be useful, but (IMHO) the effort and portability problems discourage their use.
