Specified by:

addReference in interface Thing

Overrides:

addReference in class ThingImpl

Parameters:

listener - The listener for changes.

removeReference

public final void removeReference(ThingReference listener)

Removes a listener for changes to this instance. Because instances of this class don't change, this method does nothing.

Specified by:

removeReference in interface Thing

Overrides:

removeReference in class ThingImpl

Parameters:

listener - The change listener to be removed.

getValues

public double[] getValues()
