Class ServerContext

java.lang.Object
  javax.rad.server.ServerContext

Direct Known Subclasses:

ServerContextImpl

public abstract class ServerContext
extends Object

A ServerContext contains all of the per-request state information related to the processing of a single server call. It is passed to, and potentially modified by, each phase of the request processing lifecycle.

A ServerContext instance remains active until its release() method is called.

While a ServerContext instance is active, it must not be referenced from any thread other than the one upon which the server executing this application utilizes for the processing of this call.
