#include <CompareTrans.h>
Inheritance diagram for CompareTrans< T >:
You will need to specify an event mask which will be listened for. This event will then be listened for - each time it is received, CompareTrans will check the values for possible activation.
For example, if you want to transition when the IR sensor goes below, say 200, pass &state->sensors[IRDistOffset], CompareTrans::LT, 200, and EventBase(EventBase::sensorEGID,SensorSourceID::UpdatedSID,EventBase::statusETID) as the polling event. Or a timer event to just check at a certain interval.
If you pass a class as the templated type, only requires that < operator is defined for comparing inequality, == for equality, and a copy constructor (CompareTrans holds a protected copy of the value)
Passing NULL as the value to monitor will cause a transition on the first event received
