The atg.epub.servlet.SegmentAssetFormHandler lets you create and update segment assets. Each segment is made up of properties and property values called characteristics. You can add and remove characteristics from your segments using this form handler.

This class uses a request-scoped component that temporarily stores its contents in the session-scoped asset info component defined for a given page. That way, one SegmentAssetFormHandler component can service all form pages that are able to work with segment assets. ATG Content Administration includes one component of this class called /atg/epub/servlet/SegementAssetFormHandler.
