public class CvValue extends AbstractValue implements ProgListener
Encapsulate a single CV value and provide programming access to the decoder.Since this is a single CV in a single decoder, the Programmer used to get access is part of the state. This allows us to specify a specific ops-mode programmer aimed at a particular decoder.
There are three relevant parameters: Busy, Value, State. Busy == true means that a read or write operation is going on. When it transitions to "false", the operation is complete, and the Value and State are stable. During a read operation, Value changes before State, so you can assume that Value is stable if notified of a State change.

setState
public void setState(AbstractValue.ValueState state)
Set state value and send notification.Also sets GUI color as needed.- Parameters:
state
- new state, e.g READ, UNKNOWN, SAME.
-
isBusy
public boolean isBusy()
