Hello guys,
Here is a little contribution: a mock object for a PropertyChangeListener.
In correspondence to the io and sql subpackages, I put this class in a beans
subpackage, since the PropertyChangeListener interface resides in
java.beans.
---- Start of class --------------
package com.mockobjects.beans;
import java.beans.*;
import com.mockobjects.*;
/**
* Mock object for a PropertyChangeListener.
* This mock object can be used in verifying the event propagation mechanism
* of beans. You can set the information you expect from a
PropertyChangeEvent
* as well as the number of events. If you expect more than one event, only
the
* actual values of the last event are stored.
