The request queue of the configuration controller handles requests for
changes to the current configuration.
This interface allows callers to add requests to the back of the
queue and to determine wheter the queue is empty. Using this interace
should normally not be necessary for anyone else than the
XConfigurationController. It may be removed in the future.
Add a request for a configuration change to the request queue.
This method should not be called from outside the drawing
famework. Other sub conrollers of the drawing framework are typical
callers. They can add change requests that can not be made with the
requestResourceActivation() and
requestResourceDeactivation() methods.
Parameter xRequest
The configuration change represented by this request object must only
be commited to the configuration when the
execute()
method of the xRequest object is called.
