public class JoltList
extends java.awt.List
implements JoltOutputListener, java.awt.event.ItemListener

This is a Jolt-aware extension of java.awt.List, which is linked to a specific Jolt field by its JoltFieldName property. It can be wired up with JoltServiceBeans in two ways:

• JoltList contains parts of the input for a service
• JoltList displays output from a service.

In the first case a JoltServiceBean is listening to events raised by a JoltList. JoltList sends JoltInputEvents to its listeners (typically JoltServiceBeans) when the selection in the listbox changes. The JoltInputEvent in this case is populated with the single value of the selected item.

If JoltList is used to display the output of a service, JoltList listens to JoltOutputEvents from JoltServiceBeans and updates its contents accordingly with the occurrences of the Jolt field it is linked to.

Method Detail

getJoltInputEvent

public JoltInputEvent getJoltInputEvent()

Get the current JoltInputEvent object that was sent for serviceReturned.

Returns:

The JoltInputEvent.

serviceReturned

public void serviceReturned(JoltOutputEvent evt)

Event handler for JoltOutputEvents. This method should not be called directly; it is always called by the JoltServiceBean.

Specified by:

serviceReturned in interface JoltOutputListener

Parameters:

evt - The event object.

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent e)

The state of the JoltList changed; generate a JoltInputEvent and notify event listeners.

Specified by:

itemStateChanged in interface java.awt.event.ItemListener

Parameters:

e - The ItemEvent.

addJoltInputListener

public void addJoltInputListener(JoltInputListener l)

Registration method for JoltInput listeners.

Parameters:

l - The listener to be added.

removeJoltInputListener

public void removeJoltInputListener(JoltInputListener l)

This method is used to unregister JoltInput listeners.

Parameters:

l - The listener to be removed.

setOccurrenceIndex

public void setOccurrenceIndex(int occurrence)

Set the occurrence index of the field represented by this JoltList.

Parameters:

occurrence - The occurrence number.

getOccurrenceIndex

public int getOccurrenceIndex()

Get the occurrence index of the field represented by this JoltList.

Returns:

The occurrence index.

getJoltFieldName

public java.lang.String getJoltFieldName()
