◆ unassign()

void OutputFUBroker::unassign ( MoveNode & node )

overridevirtual

Free the resource type managed by this broker and unassign it from given node.

If this broker is not applicable to the given node, or the node is not assigned a resource of the managed type, this method does nothing.

Parameters
