org.araneaframework.http.ThreadCloningContext

All known Subclasses:   org.araneaframework.http.filter.StandardThreadCloningFilterService,
ThreadCloningContext
public interface ThreadCloningContext extends Serializable(Code)
Service that clones currently running session thread upon request and sends a response that redirects to cloned session thread. It can be used to support "open link in new window" feature in browsers.
author:
   Taimo Peelo


Field Summary
final public static  StringCLONE_ONLY_REQUEST_KEY
     Request parameter key which presence indicates that incoming request is requesting cloning of the current session thread.
final public static  StringCLONING_REQUEST_KEY
     Request parameter key which presence indicates that incoming request is requesting cloning of the current session thread.


Method Summary
public  byte[]acquireThreadSnapshot()
     Returns the snapshot of current thread, made before child Service of ThreadCloningContext implementation has had the chance to process the request.
public  StringstartClonedThread(RelocatableService clone)
     Attaches clone as new thread level service (see ThreadContext ).

Field Detail
CLONE_ONLY_REQUEST_KEY
final public static String CLONE_ONLY_REQUEST_KEY(Code)
Request parameter key which presence indicates that incoming request is requesting cloning of the current session thread. Presence of this should mean that snapshot of current thread is made before request is routed to child Service . Cloned thread is not attached to thread router (no new window with cloned thread will be opened). Snapshot can be acquired during the same request by calling ThreadCloningContext.acquireThreadSnapshot .
since:
   1.1



CLONING_REQUEST_KEY
final public static String CLONING_REQUEST_KEY(Code)
Request parameter key which presence indicates that incoming request is requesting cloning of the current session thread. Presence of this should mean that current thread is cloned and then cloned thread is immediately opened in a new browser window.





Method Detail
acquireThreadSnapshot
public byte[] acquireThreadSnapshot()(Code)
Returns the snapshot of current thread, made before child Service of ThreadCloningContext implementation has had the chance to process the request. Only applicable when request contained either ThreadCloningContext.CLONE_ONLY_REQUEST_KEY or ThreadCloningContext.CLONING_REQUEST_KEY parameter. Deserialization of the snapshot could be done as follows:

ObjectInputStream ois = new ObjectInputStream(new ByteArrayInputStream(acquireSerializedThread())); RelocatableService clone = (RelocatableService) ois.readObject();

Snapshot may then be started as cloned thread with ThreadCloningContext.startClonedThread(RelocatableService) . serialized snapshot of current thread or null
since:
   1.1



startClonedThread
public String startClonedThread(RelocatableService clone)(Code)
Attaches clone as new thread level service (see ThreadContext ). It assumes that the service is already initialized and thus will not attempt to reinitialize it (as using ManagedServiceContext.addService(Objectorg.araneaframework.Service) would try to do).
Parameters:
  clone - cloned service to start as new session level thread identifier of created session thread
since:
   1.1
