Public Methods | |
| ACE_Test_and_Set (TYPE initial_value=0) | |
| TYPE | is_set (void) const |
| Returns true if we are set, else false. | |
| TYPE | set (TYPE) |
| virtual int | handle_signal (int signum, siginfo_t *=0, ucontext_t *=0) |
Private Attributes | |
| TYPE | is_set_ |
| Keeps track of our state. | |
| ACE_LOCK | lock_ |
| Protect the state from race conditions. | |
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.
