Class RowKeyChangeEvent

java.lang.Object
java.util.EventObject
org.apache.myfaces.trinidad.model.RowKeyChangeEvent

All Implemented Interfaces:

Serializable

public class RowKeyChangeEvent

extends EventObject

Event that is generated when RowKey changes. This event is fired when a row is updated, inserted or deleted The oldRowKey or new RowKey can be NULL The serialization behavior depends on the implementation of the collectionModel that consumes the RowKeyChangeEvent. If the collectionModel implementation is serializable and keeps track of row key change events that it recevies, then these events are serialized with the model; otherwise, the events are not serialized
