Class RawRtfParser

java.lang.Object

com.rtfparserkit.parser.raw.RawRtfParser

All Implemented Interfaces:

IRtfParser

public class RawRtfParser
extends java.lang.Object
implements IRtfParser

This class implements a low level RTF parser. It performs the minimum amount of processing on the data read from an RTF file, just passing the caller a stream of events representing the commands and character bytes. In particular the parser doesn't not deal with character encodings or the various Unicode related commands which may be present in an RTF file. This code is based on the approach outlined in the sample C code provided in the RTF Specification 1.9.1 (http://www.microsoft.com/en-gb/download/details.aspx?id=10725)
