Interface ContentFragment

All Superinterfaces:

BaseElement, Fragment, SecuredResource, Serializable

public interface ContentFragment
extends Fragment

ContentFragment provides a volatile wrapper interface for actual Fragment metadata objects. Since Fragments are cached and are not request specific they cannot be used to store request-level content. This is where we use the ContentFragment to solve this problem.
