Interface PVReaderListener<T>

Type Parameters:

T - the type of reader for the listener

All Known Implementing Classes:

CountDownPVReaderListener

public interface PVReaderListener<T>

Callback for any change in the PV value. Cannot simply use a PropertyChangedListener because the payload of the PV will be typically updated in place for complex data structures, and therefore the data object is the same and would not trigger a PropertyChangedEvent.
