Method Summary

int	getPackedLength(int nBytes) Returns the number of bytes required to interpret a byte array of length nBytes.
void	interpret(byte[] data, byte[] b, int offset) Converts the binary data into a different interpretation or coding.
byte[]	uninterpret(byte[] rawData, int offset, int length) Converts the raw byte array into a uninterpreted byte array.

Method Detail

interpret

void interpret(byte[] data,
               byte[] b,
               int offset)

Converts the binary data into a different interpretation or coding. Standard interpretations are ASCII Hex, EBCDIC Hex, BCD and LITERAL.

Parameters:

data - The data to be interpreted.

b - The byte array to write the interpreted data to.

offset - The starting position in b.

uninterpret

byte[] uninterpret(byte[] rawData,
                   int offset,
                   int length)

Converts the raw byte array into a uninterpreted byte array. This reverses the interpret method.

Parameters:

rawData - The interpreted data.

offset - The index in rawData to start uninterpreting at.

length - The number of uninterpreted bytes to uninterpret. This number may be different from the number of raw bytes that are uninterpreted.

Returns:

The uninterpreted data.

getPackedLength

int getPackedLength(int nBytes)

Returns the number of bytes required to interpret a byte array of length nBytes.
