All Implemented Interfaces:

ConstraintEvent, Serializable

public class ConstraintUserPropertyEvent
extends ConstraintPropertyEvent

ConstraintUserPropertyEvent is fired by an IlvGeneralConstraint both before and after a user-defined property is modified. Immediately before a property is modified, an IlvGeneralConstraint fires an aboutToChange ConstraintUserPropertyEvent to all listeners registered with the Gantt data model. Listeners can modify or constrain the proposed property change by calling setNewValue(java.lang.Object). Alternatively, a listener can veto the proposed change by calling IlvPropertyEvent.veto(). If the property change is not vetoed, then IlvGeneralConstraint will apply the change and fire a changed ConstraintUserPropertyEvent to all listeners registered with the Gantt data model.

Constructor Detail

ConstraintUserPropertyEvent

public ConstraintUserPropertyEvent(IlvConstraint constraint,
                                   String property,
                                   Object oldValue,
                                   Object newValue,
                                   boolean aboutToChangeEvent)

Creates a new ConstraintUserPropertyEvent generated by the specified constraint.

Parameters:

constraint - The constraint where the event originated.

property - The name of the property.

oldValue - The property's previous value.

newValue - The property's new value.

aboutToChangeEvent - true if this is a property aboutToChange event or false if this is a property changed event.

Method Detail

getPropertyName

public String getPropertyName()

Returns the name of the property that has been modified.

getOldValue

public final Object getOldValue()

Returns the old value of the property. If this is a property aboutToChange event, this will be the same as the current value of the property since the change has not actually occurred yet. If this is a property changed event, this will be the property value prior to the current modification being reported.

Overrides:

getOldValue in class IlvPropertyEvent

getNewValue

public Object getNewValue()

Returns the new value of the property. If this is a property aboutToChange event, this will be the proposed value of the property. If this is a property changed event, this will be the new value of the property which is being reported.

Overrides:

getNewValue in class IlvPropertyEvent

setNewValue

public void setNewValue(Object newValue)

Sets the proposed new value of the property. This method has meaning only if this is a property aboutToChange event.

Overrides:

setNewValue in class IlvPropertyEvent

Parameters:

newValue - The new value of the property.
