Detailed Description

template<class ACE_LOCK, class TYPE>
class ACE_Test_and_Set< ACE_LOCK, TYPE >

Implements the classic ``test and set'' operation.

This class keeps track of the status of <is_set_>, which can be set based on various events (such as receipt of a signal). This class is derived from ACE_Event_Handler so that it can be "signaled" by a Reactor when a signal occurs. We assume that <TYPE> is a data type that can be assigned the value 0 or 1.
