23.19 java.beans.PropertyVetoException (JDK 1.1)

The PropertyVetoException signals that a VetoableChangeListener that received a PropertyChangeEvent for a "constrained" property of a bean has vetoed that proposed change.

When this exception is received, the property in question should revert back to its original value, and any VetoableChangeListener objects that have already been notified of the property change must be re-notified to indicate that the property has reverted to its old value. The VetoableChangeSupport class handles this re-notification automatically and re-throws the PropertyVetoException to notify its caller that the change was rejected.

public class PropertyVetoException extends Exception {
    // Public Constructor
            public PropertyVetoException(String mess, PropertyChangeEvent evt);
    // Public Instance Methods
            public PropertyChangeEvent getPropertyChangeEvent();
