Method Detail

addReference

public final void addReference(ThingReference listener)

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

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.

equals

public abstract boolean equals(Object obj)

Indicates if this scalar is semantically identical to an object.

Specified by:

equals in interface ScalarIface

Overrides:

equals in class Object

Parameters:

obj - The object.

Returns:

true if and only if this scalar is semantically identical to the object.

clone

public final Object clone()

Clones this instance.

Overrides:

clone in class DataImpl

Returns:

A clone of this instance.
