Class NullMessageOutput

java.lang.Object

net.sf.jguiraffe.gui.builder.utils.NullMessageOutput

All Implemented Interfaces:

MessageOutput

public class NullMessageOutput
extends Object
implements MessageOutput

An implementation of the MessageOutput interface that does not output a message.

This class provides an empty implementation of the show() method. Therefore messages are effectively suppressed. An instance of this class can be used when a MessageOutput object is required, but no message boxes are to be displayed, e.g. because there is an alternative way of giving feedback to the user.
