com.levigo.jadice.web.shared.model.PageSegmentHandle

com.levigo.jadice.web.client.messaging.data.GenericPageSegmentHandle

All Implemented Interfaces:

Serializable

public class GenericPageSegmentHandle
extends PageSegmentHandle

A generic PageSegmentHandle/Source that only lives on the client, specially made for the TypeScript Viewer. In the TS-Viewer you can use pretty much every JSON-structure as a Source. In the GWT-part, we will struggle with untyped Objects. We therefore use these generic classes to transport customer-specific data in a generic params-field as the GWT-Jadice-renderer is only interested in the fields of a handle that come from the abstract class PageSegmentHandle (pageIndex, documentLayer,...). On the Backend-side there is no such thing as a generic Handle/Source. The type tells the Backend to which custom Handle/Source this will be deserialized (the params will be deserialized do a specific Handle/Source-class). This seems to be a proper solution to handle untyped JS together with typed GWT.
