RowSetListener

AI-generated Key Takeaways

• The RowSetListener interface enables components to be notified of significant events occurring within a RowSet object.

• Components register as listeners using RowSet.addRowSetListener and define their event handling logic by implementing the interface methods.

• Three key events are covered: cursorMoved, signaling cursor movement; rowChanged, indicating changes within a row; and rowSetChanged, signifying changes to the entire RowSet content.

• All event notifications provide a RowSetEvent object containing the source RowSet for identifying the origin of the event.

public interface RowSetListener implements EventListener

An interface that must be implemented by a component that wants to be notified when a significant event happens in the life of a RowSet object. A component becomes a listener by being registered with a RowSet object via the method RowSet.addRowSetListener. How a registered component implements this interface determines what it does when it is notified of an event.

Public Method Summary

abstract void	cursorMoved(RowSetEvent event) Notifies registered listeners that a RowSet object's cursor has moved.
abstract void	rowChanged(RowSetEvent event) Notifies registered listeners that a RowSet object has had a change in one of its rows.
abstract void	rowSetChanged(RowSetEvent event) Notifies registered listeners that a RowSet object in the given RowSetEvent object has changed its entire contents.

Public Methods

public abstract void cursorMoved (RowSetEvent event)

Notifies registered listeners that a RowSet object's cursor has moved.

The source of the event can be retrieved with the method event.getSource.

Parameters

event	a RowSetEvent object that contains the RowSet object that is the source of the event

public abstract void rowChanged (RowSetEvent event)

Notifies registered listeners that a RowSet object has had a change in one of its rows.

The source of the event can be retrieved with the method event.getSource.

Parameters

event	a RowSetEvent object that contains the RowSet object that is the source of the event

public abstract void rowSetChanged (RowSetEvent event)

Notifies registered listeners that a RowSet object in the given RowSetEvent object has changed its entire contents.

The source of the event can be retrieved with the method event.getSource.

Parameters

event	a RowSetEvent object that contains the RowSet object that is the source of the event
