Package com.rtfparserkit.parser.standard

Class UprHandler

  • All Implemented Interfaces:
    IParserEventHandler
    public class UprHandler
extends java.lang.Object
implements IParserEventHandler
    The upr command is used to wrap two different versions of the same set of formatting commands. The first set of formatting commands uses ANSI encoding, the second set uses Unicode. The upr command is expected to appear in its own group, so this handler can be used to consume all of the RTF events received up to the end of the group It can then pass the Unicode version of the command it wraps to the listener, discarding the ANSI version.
