Interface BinaryInterpreter

All Known Implementing Classes:

AsciiHexInterpreter, EbcdicBinaryInterpreter, EbcdicHexInterpreter, LiteralBinaryInterpreter

public interface BinaryInterpreter

This interface supports the encoding and decoding of binary data. Common implementations are literal or no conversion, ASCII Hex, EBCDIC Hex and BCD.

Method Summary

Modifier and Type	Method and Description
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.
