com.ibm.portal.model.controller
Interface ContentModelControllerResumeService

All Superinterfaces:
ContentModelProvider
public interface ContentModelControllerResumeService
extends ContentModelProvider

The future - may be implemented after web2.0 tech preview: allow management of content model controllers across a prolonged time, e.g. multiple requests. Storage/lifetime is implied by how this service is obtained (e.g. if it is obtained using a session object, it can be assumed the controller is suspended to the session etc.)

Since:
6.1.0
