All Implemented Interfaces

javax.servlet.http.HttpServletRequest, javax.servlet.ServletRequest, ScopedRequest

public class ScopedRequestImpl

extends javax.servlet.http.HttpServletRequestWrapper

implements ScopedRequest

A wrapper around HttpServletRequest, associated with a given scope-key. All calls to setAttribute, getAttribute, removeAttribute, etc. are scoped to this object, while most other functionality delegates to the wrapped HttpServletRequest. Instances of this class also keep track of their own request-URIs, which are independent of the wrapped request-URIs.
