Parameters:

listener - The listener to add.

clearCurrent

public static void clearCurrent()

Removes the RequestContext object of the current thread.

createCurrent

public static RequestContext createCurrent()

The newly created RequestContext object.

getCurrent

public static RequestContext getCurrent()

Gets the current RequestContext object from the current thread.

Returns:

RequestContext.

hasContext

public static boolean hasContext()

Returns true if a current context exists.

Returns:

true if a current context exists.

notifyListener

public static void notifyListener(com.bea.wlcp.wlng.plugin.context.RequestContextListenerEvent event)

Notify the RequestContext listeners of an event. This method is not synchronized for performance reasons. It is assumed that adding/removing listeners only happens at startup/shutdown, before any traffic exists.

Parameters:

event - The event of event.

notifyListener

public static void notifyListener(com.bea.wlcp.wlng.plugin.context.RequestContextListenerEvent event,
                                  com.bea.wlcp.wlng.plugin.context.RequestContextListenerData data)

Notify the RequestContext listeners of an event. This method is not synchronized for performance reasons. It is assumed that adding/removing listeners only happens at startup/shutdown, before any traffic exists.

Parameters:

event - The event of event.

data - The request context listener data.

removeListener

public static void removeListener(com.bea.wlcp.wlng.plugin.context.RequestContextListener listener)

Removes a RequestContext listener from the manager.

Parameters:

listener - The listener to remove.

setCurrent

public static void setCurrent(RequestContext context)

Set the request context. This operation can be used for handling asynchronous flows where Request context needs to be transferred from one Thread to another.
