createSourceHandle

public ServerBasedDnDHandle createSourceHandle(ServerBasedDnDSource source)

Description copied from interface: DocumentDataProvider

Creates a SourceHandle from a given Source. The information required to recover the document must be stored in the PageSegmentHandle. The web toolkit server will call the DocumentDataProvider.recover(Reader, PageSegmentHandle) method with a PageSegmentHandle. Typical scenarios include garbage-collected documents, a server restart, or moving a request to another server for load-balancing or fail-over purposes.

Parameters:

source - The Source the Handle should be created from.

Returns:

The PageSegmentHandle to recover the document stream.
