Class ValueChangeVerifier

java.lang.Object

org.yamcs.commanding.ValueChangeVerifier

All Implemented Interfaces:

ParameterConsumer

public class ValueChangeVerifier
extends Object
implements ParameterConsumer

Command verifier which succeeds when a parameter changes with a delta above a threshold.

The parameter is first sampled when the verifier starts and that value is compared with the new values when received.

This verifier never fails but it timeouts if the value does not change (enough)
