weblogic.workarea

Class WorkContextHelper

java.lang.Object

weblogic.workarea.WorkContextHelper

All Implemented Interfaces:

weblogic.core.base.api.FastThreadLocalMarker

@Service
public class WorkContextHelper
extends java.lang.Object
implements weblogic.core.base.api.FastThreadLocalMarker

WorkContextHelper allows internal users to obtain and modify WorkContexts. The class APIs allow for replacement of the implementation - although there are currently no use-cases for this. Typical usages follow. To obtain the current WorkContextMap for update:

 WorkContextMap interceptor 
   = WorkContextHelper.getWorkContextHelper().getWorkContextMap();

To obtain a WorkContextMapInterceptor:

 WorkContextMapInterceptor interceptor 
   = WorkContextHelper.getWorkContextHelper().getInterceptor();

WorkContextMap, WorkContextMapInterceptor

Method Detail

getWorkContextHelper

public static WorkContextHelper getWorkContextHelper()

Get the WorkContextHelper singleton.

Returns:

A suitable WorkContextHelper implementation for client or server.

setWorkContextHelper

public static void setWorkContextHelper(WorkContextHelper wam)

Set the WorkContextHelper singleton. This should be set at startup and not synchronized.

Parameters:

wam - - a suitable WorkContextHelper implementation for client or server.

getWorkContextMap

public WorkContextMap getWorkContextMap()

getPriviledgedWorkContextMap

public WorkContextMap getPriviledgedWorkContextMap()

getInterceptor

public weblogic.workarea.spi.WorkContextMapInterceptor getInterceptor()

Get the singleton instance of the current WorkContextMapInterceptor..

Returns:

A suitable WorkContextMapInterceptor implementation for client or server.

getLocalInterceptor

public weblogic.workarea.spi.WorkContextMapInterceptor getLocalInterceptor()

Get the singleton thread-local instance of the current WorkContextMapInterceptor, or null if there is no WorkContextMap for the current thread.

Returns:

A suitable WorkContextMapInterceptor implementation for client or server.

createInterceptor

public weblogic.workarea.spi.WorkContextMapInterceptor createInterceptor()

Create an instance of WorkContextMapInterceptor for the purposes of serialization. Thread infection can be achieved via WorkContextHelper.setLocalInterceptor(weblogic.workarea.spi.WorkContextMapInterceptor).

Returns:

A suitable WorkContextMapInterceptor implementation for client or server.

setLocalInterceptor

public void setLocalInterceptor(weblogic.workarea.spi.WorkContextMapInterceptor interceptor)

Take an WorkContextMapInterceptor object and make it the current map. This bypasses serialization schemes for the WorkContextMap. This allows callers to separate serialization from thread infection and vice versa.
