Interface IBreadCrumbParticipant

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

BreadCrumbPanel

public interface IBreadCrumbParticipant

extends java.io.Serializable

Bread crumb participants function as proxies for components that are part of a bread crumb hierarchy. An example of a bread crumb is:

     Home > Products & Solutions > Hardware > Desktop Systems
 

In a panel based implementation, Home, Products & Solutions etc would be seperate panels that all are bread crumb participants: for instance the Home participant's title would return 'Home', and the component would be the corresponding panel.
