Class BinaryTokenizer

java.lang.Object
  com.americancoders.edi.BinaryTokenizer

All Implemented Interfaces:

IDataTokenizer

public class BinaryTokenizer

extends java.lang.Object

implements IDataTokenizer

Field Summary

protected java.util.Vector	allTokens where all the substrings are stored
protected int	currentPos current position within tokenized string
protected int	stringLength length of field
protected java.lang.String	tokens what breaks up fields
protected java.lang.String	tokenString current tokenized string

Constructor Summary

BinaryTokenizer(java.lang.String inString, java.lang.String inTokens, ReaderTokenizer mainTokenizer)
constructor for Binary Tokenizer (X12 BIN Segments)
first field contains length of data
second field contains binary data (including token seperators)
so if the incoming string is too short, we must go back to the main tokeninzer and ask for the rest of the string

Method Summary

int	countTokens() how many tokens in list
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
java.lang.String	getTokenString()
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

Constructor Detail

BinaryTokenizer

public BinaryTokenizer(java.lang.String inString,
                       java.lang.String inTokens,
                       ReaderTokenizer mainTokenizer)
                throws OBOEException

constructor for Binary Tokenizer (X12 BIN Segments)
first field contains length of data
second field contains binary data (including token seperators)
so if the incoming string is too short, we must go back to the main tokeninzer and ask for the rest of the string

Parameters:

inString - incoming string to tokenize

inTokens - token seperators

mainTokenizer - tokenizer that does that bulk of the work

Throws:

OBOEException - - most likely length error

Method Detail

nextToken

public java.lang.String nextToken()

to get next token

Specified by:

nextToken in interface IDataTokenizer

Returns:

String - the next token

getTokenAt

public java.lang.String getTokenAt(int pos)

gets the token in tokenized string at a specifiec position

Specified by:

getTokenAt in interface IDataTokenizer

Parameters:

pos - int position, if < 0 or > the total returns null

Returns:

String

hasMoreElements

public boolean hasMoreElements()

indicates if there are more data elements to parse

Specified by:

hasMoreElements in interface IDataTokenizer

Returns:

boolean more to parse?

countTokens

public int countTokens()

how many tokens in list

Specified by:

countTokens in interface IDataTokenizer

Returns:

int - a count

getTokenString

public java.lang.String getTokenString()

getPositionInStream

public int getPositionInStream()

Description copied from interface: IDataTokenizer

returns the byte offset position of the token in the overall input stream

Specified by:

getPositionInStream in interface IDataTokenizer

Returns:

int

setPositionInStream

public void setPositionInStream(int positioninStream)

Description copied from interface: IDataTokenizer

sets the byte offset position of the token in the input stream

Specified by:

setPositionInStream in interface IDataTokenizer
