public final class RtfDestinationNull
extends RtfDestination

RtfDestinationNull is for discarded entries. They go nowhere. If a control word destination is unknown or ignored, this is the destination that should be set. All methods return true indicating they were handled. This is a unique destination in that it is a singleton.
