class CTimedTrigger : public CEventTrigger {CTimedTrigger(const timespec& interval);CTimedTrigger(const CTimedTrigger& interval);void setPeriod(const struct timespec& newInterval);virtual void setup();virtual bool operator()();}
Provides a concrete CEventTrigger class
that fires periodically. Note that the trigger is not latched, that
that is once operator() returns
true it won't do so again until the trigger is
next due to fire.
This is the typical event trigger attached to scaler readout.
CTimedTrigger(const timespec& interval);
Constructs a trigger that will fire periodically. The
trigger interval is interval.
This can be modified by calling setPeriod
CTimedTrigger(const CTimedTrigger& interval);
Copy construction.
void setPeriod(const struct timespec& newInterval);
Sets the new trigger period. This takes effect immediately. If
the time since the last trigger is greater than
newInterval the next call to
operator() will return
true.
virtual void setup();
Initializes the trigger by setting the last fired time to now.
virtual bool operator()();
Returns true if the last trigger was more longer ago than the trigger period.
