  +--com.americancoders.edi.ReaderTokenizer

All Implemented Interfaces:

IDataTokenizer

public class ReaderTokenizer

extends java.lang.Object

implements IDataTokenizer

Tokenizes from a Reader Object

Field Summary

protected int	currentPos current position within tokenized string
protected java.lang.String	escapeCharacters escape characters to allow tokens in the text
protected java.io.PushbackReader	tokenReader current tokenized string
protected java.lang.String	tokens what breaks up fields

Constructor Summary

ReaderTokenizer(java.io.Reader inReader, java.lang.String inTokens, java.lang.String inEscapeCharacters)
constructor

Method Summary

int	countTokens() how many tokens in list
byte[]	getMoreData(int inLength) pulls more data out of reader stream for binarytokenizer
int	getPositionInStream() returns the byte offset position of the token in the overall input stream
java.lang.String	getTokenAt(int pos) gets the token in tokenized string at a specifiec position
boolean	hasMoreElements() indicates if there are more data elements to parse
java.lang.String	nextToken() to get next token
void	setPositionInStream(int positionInStream) sets the byte offset position of the token in the input stream
void	setSkipChar(char inChar)
