Constructors Summary

public PropertyChangeEvent(Object source, String propertyName, Object oldValue, Object newValue) The constructor used to create a new {@code PropertyChangeEvent}. param source the changed bean. param propertyName the changed property, or null to indicate an unspecified set of the properties has changed. param oldValue the previous value of the property, or null if the propertyName is null or the previous value is unknown. param newValue the new value of the property, or null if the propertyName is null or the new value is unknown. super(source); this.propertyName = propertyName; this.oldValue = oldValue; this.newValue = newValue;

Methods Summary
public java.lang.Object	getNewValue() Returns the new value that the property now has. If the new value is unknown this method returns null. return the old property value or null. return newValue;
public java.lang.Object	getOldValue() Returns the old value that the property had. If the old value is unknown this method returns null. return the old property value or null. return oldValue;
public java.lang.Object	getPropagationId() Returns the propagationId object. This is reserved for future use. Beans 1.0 demands that a listener receiving this property and then sending its own PropertyChangeEvent sets the received propagationId on the new PropertyChangeEvent's propagationId field. return the propagationId object. return propagationId;
public java.lang.String	getPropertyName() Returns the name of the property that has changed. If an unspecified set of properties has changed it returns null. return the name of the property that has changed, or null. return propertyName;
public void	setPropagationId(java.lang.Object propagationId) Sets the propagationId object. see #getPropagationId() this.propagationId = propagationId;
