## com.lowagie.text.rtf.parser.destinations
Class RtfDestinationNull

    java.lang.Object
      com.lowagie.text.rtf.parser.destinations.RtfDestination
          com.lowagie.text.rtf.parser.destinations.RtfDestinationNull

    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.
