Examples of java.beans.VetoableChangeListener

java.beans.VetoableChangeListener
A VetoableChange event gets fired whenever a bean changes a "constrained" property. You can register a VetoableChangeListener with a source bean so as to be notified of any constrained property updates.

        // check vetoable change listeners
        VetoableChangeSupport origVCS = (VetoableChangeSupport) Utils.getField(
                orig, "vcSupport");
        VetoableChangeSupport serVCS = (VetoableChangeSupport) Utils.getField(
                ser, "vcSupport");
        VetoableChangeListener origVCL[] = origVCS
                .getVetoableChangeListeners("beanContext");
        VetoableChangeListener serVCL[] = serVCS
                .getVetoableChangeListeners("beanContext");
        i = 0;
        j = 0;
        while (i < origVCL.length) {
            if (origVCL[i] instanceof Serializable) {
