All Implemented Interfaces:

ActivityEvent, Serializable

public class ActivityIDEvent
extends ActivityPropertyEvent

ActivityIDEvent is fired by an IlvActivity both before and after its id is modified. Immediately before its id is modified, an IlvActivity fires an aboutToChange ActivityIDEvent in all listeners registered with the Gantt data model. Listeners can modify or constrain the proposed id by invoking setNewID(). Alternatively, a listener can veto the proposed change by invoking veto().

After its id is modified, an IlvActivity will fire a changed ActivityIDEvent in all listeners registered with the Gantt data model. Listeners can access the old and new values of the activity's id, but cannot modify them via the event mechanism.

Constructor Detail

ActivityIDEvent

public ActivityIDEvent(IlvActivity activity,
                       String oldID,
                       String newID,
                       boolean aboutToChangeEvent)

Constructs a new ActivityIDEvent generated by the specified activity and with the specified old and new id values.

Parameters:

activity - the activity where the event originated

oldID - the activity's previous id

newID - the activity's new id

aboutToChangeEvent - true if this is an activityIDAboutToChange event or false if this is an activityIDChanged event.

Method Detail

getOldID

public String getOldID()

Returns the activity's old id. If this is a activityIDAboutToChange event, then this will be the same as the activity's current id since the change has not actually occurred yet. If this is a activityIDChanged event, this will be the activity's id prior to the current modification being reported.

Returns:

The String representing the activity's old id.

getNewID

public String getNewID()

Returns the activity's new id. If this is a activityIDAboutToChange event, then this is will be the activity's proposed value. If this is a activityIDChanged event, this will be the activity's new id which is being reported.

Returns:

The String representing the activity's new id.

setNewID

public void setNewID(String id)

Sets the activity's proposed new id. This method only has meaning if this is a activityIDAboutToChange event. By using this method, a listener can constrain changes to the activity's id.

Parameters:

id - the activity's id
