.SH DETAILED DESCRIPTION
.PP
.SS template<class ACE_LOCK, class TYPE> template class ACE_Test_and_Set
Implements the classic ``test and set'' operation.
.PP
.PP
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 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.

.PP
Called when object is signaled by OS (either via UNIX signals or when a Win32 object becomes signaled).
.PP
Reimplemented from \fBACE_Event_Handler\fR.
