All Implemented Interfaces:

Runnable, SharedObjectListener, AALSpaceListener

public class UIStrategyCaller
extends UIStrategyHandler

This part of the UIStrategy Stack deals only with communications between the UICallers and the IDialogManager.

the messages exchaged are:

1. Request: the UICaller notifies the IDialogManager there is a new UIRequest it whants to display to a user. When ready a UIResponse will be delivered.
2. suspend a dialog: the UICaller notifies the IDialogManager a dialog should be suspendend for later resume.
3. resume a dialog: a notification for resuming a previously suspended dialog.
4. abort a dialog: a dialog is no longer valid the UICaller calls for its removal, the data inputed until cancelation will be delibered. Aborts may also be instructed by the IDialogManager in representation of the user.
