Summary: Have hbm2java generate support for veto and change listeners
Initial Comment:
How about adding somemore JavaBeans Functionality,
namely the PropertyChange- and
VetoableChangeMechanism.
I envision something like
<property ... changeType="[bound|constraint]" />
which would lead to the incorporation of the appropriate
SupportClass and the Eventfiring code to the setter
Methods.
Specifically I am refering to
1) the hibernate codegenerator
2) JavaBeans Spec. 1.0.1 Sect. 7.4
Thus the SupportClass is given by the appropriate classes
in the beans package;
the code should look somewhat like this:
import java.awt.*;
import java.beans.*;
public class JellyBean {
public Color getColor() {
return ourColor;
}
public void setColor(Color newColor) {
Color oldColor = ourColor;
ourColor = newColor;
changes.firePropertyChange( color , oldColor, newColor);
}
public int getPriceInCents() {
return ourPriceInCents;
}
public void setPriceInCents(int newPriceInCents) throws
PropertyVetoException {
int oldPriceInCents = ourPriceInCents; // First tell the
vetoers about the change. If anyone objects, we
// let the PropertyVetoException propagate back to our
caller.
vetos.fireVetoableChange( priceInCents , new
Integer(oldPriceInCents), new Integer(newPriceInCents));
// No one vetoed, so go ahead and make the change.
ourPriceInCents = newPriceInCents;
changes.firePropertyChange( priceInCents , new
Integer(oldPriceInCents), new Integer(newPriceInCents));
}
public void
addPropertyChangeListener(PropertyChangeListener l) {
changes.addPropertyChangeListener(l);
}
public void
removePropertyChangeListener(PropertyChangeListener l)
{
changes.removePropertyChangeListener(l);
}
public void
addVetoableChangeListener(VetoableChangeListener l) {
vetos.addVetoableChangeListener(l);
}
public void
removeVetoableChangeListener(VetoableChangeListener l)
{
vetos.removeVetoableChangeListener(l);
}
private PropertyChangeSupport changes = new
PropertyChangeSupport(this);
private VetoableChangeSupport vetos = new
VetoableChangeSupport(this);
private Color ourColor = Color.orange;
private int ourPriceInCents = 2;
}
