All Implemented Interfaces:
java.io.Serializable

public class EntityEvent
extends java.util.EventObject

An event delivered to an EventListener to notify of changes to data at the Entity Object level.

The event type, which indicates the cause of the event, is one of ATTRIBUTE_CHANGE, STATE_CHANGE, or BEFORE_REMOVE. ATTRIBUTE_CHANGE events contain indices of changed attributes, as well as an array of the old attribute values. STATE_CHANGE events contain the old post state.

JDeveloper 3.0

static int BEFORE_REMOVE
          An event type indicating that the Entity Object's row is to be removed.
static int STATE_CHANGE
          An event type indicating that the Entity Object's post state data has changed.

Constructor Detail

EntityEvent

public EntityEvent(EntityImpl source,
                   int eventType,
                   int oldState,
                   int[] changedColumns,
                   java.lang.Object[] origValues)
Constructs a new Entity Object event.

Parameters:
source - the Entity Object row that fired the event.
eventType - the type of event. One of ATTRIBUTE_CHANGE, STATE_CHANGE, or BEFORE_REMOVE.
oldState - the post state of Entity Object row before it was changed. This parameter is relevant only for STATE_CHANGE events.
changedColumns - an array of the indices of changed attributes. This parameter is relevant only if the event type is ATTRIBUTE_CHANGE.
origValues - an array of the previous attribute values. This parameter is relevant only if the event type is ATTRIBUTE_CHANGE.
