Field Summary

static AsciiHexInterpreter

INSTANCE An instance of this Interpreter.

Constructor Summary

AsciiHexInterpreter()

Method Summary

int	getPackedLength(int nBytes) Returns double nBytes because the hex representation of 1 byte needs 2 hex digits.
void	interpret(byte[] data, byte[] b, int offset) Converts the binary data into ASCII hex digits.
byte[]	uninterpret(byte[] rawData, int offset, int length) Converts the ASCII hex digits into binary data.

Field Detail

INSTANCE

public static final AsciiHexInterpreter INSTANCE

An instance of this Interpreter. Only one needed for the whole system

Constructor Detail

AsciiHexInterpreter

public AsciiHexInterpreter()

Method Detail

interpret

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

Converts the binary data into ASCII hex digits.

Specified by:

interpret in interface BinaryInterpreter

Parameters:

data - The data to be interpreted.

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

offset - The starting position in b.

See Also:

BinaryInterpreter.interpret(byte[], byte[], int)

uninterpret

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

Converts the ASCII hex digits into binary data.

Specified by:

uninterpret in interface BinaryInterpreter

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.

See Also:

BinaryInterpreter.uninterpret(byte[], int, int)

getPackedLength

public int getPackedLength(int nBytes)

Returns double nBytes because the hex representation of 1 byte needs 2 hex digits.

Specified by:

getPackedLength in interface BinaryInterpreter
