public class ByteBuffer
extends Object

This is a utility class to write bytes into a buffer taking into account endianess.

Constructor Summary

ByteBuffer(boolean bLittleEndian)
Constructs a buffer for writing.

ByteBuffer(boolean bLittleEndian, int iLength)
Constructs a buffer for writing.

ByteBuffer(byte[] bytes)
Constructs a buffer for reading.

ByteBuffer(int iLength)
Constructs a buffer for writing.

Method Summary

byte[]	getBytes() Gets the bytes for the buffer.
static void	main(String[] args) Exerciser
byte	readByte(int iOffset) Gets a byte from the offset of the byte array.
byte[]	readBytes(int iOffset, int iLen) Gets a series of bytes from the byte array
int	readInt(int iOffset, boolean bLittleEndian) Gets an integer from the offset of the byte array.
long	readLong(int iOffset, boolean bLittleEndian) Gets a long from the offset of the byte array.
short	readShort(int iOffset, boolean bLittleEndian) Gets a short from the offset of the byte array.
int	readShortAsInt(int iOffset, boolean bLittleEndian) Gets a short from the offset of the byte array.
void	writeByte(byte yValue) Writes a byte to the buffer
void	writeBytes(byte[] yBytes) Writes a series of bytes, in order.
void	writeInt(int iValue) Writes an integer to the buffer
void	writeLong(long lValue) Writes a long to the buffer

Constructor Detail

ByteBuffer

public ByteBuffer(boolean bLittleEndian)

Constructs a buffer for writing. The initial buffer size is zero bytes.

Parameters

bLittleEndian - true if the data should be written in little-endian order, false for big endian

ByteBuffer

public ByteBuffer(int iLength)

Constructs a buffer for writing. The buffer is constructed big-endian.

Parameters

iLength - the initial size of the buffer written in little-endian order, false for big endian

ByteBuffer

public ByteBuffer(boolean bLittleEndian,
                  int iLength)

Constructs a buffer for writing.

Parameters

bLittleEndian - true if the data should be written in little-endian order, false for big endian

ByteBuffer

public ByteBuffer(byte[] bytes)

Constructs a buffer for reading.

Method Detail

getBytes

public byte[] getBytes()

Gets the bytes for the buffer.

writeInt

public void writeInt(int iValue)

Writes an integer to the buffer

Parameters

iValue - the integer value

writeLong

public void writeLong(long lValue)

Writes a long to the buffer

Parameters

iValue - the integer value

writeByte

public void writeByte(byte yValue)

Writes a byte to the buffer

writeShort

public void writeShort(short shValue)

Writes a short to the buffer

Parameters

iValue - the integer value

readInt

public int readInt(int iOffset,
                   boolean bLittleEndian)

Gets an integer from the offset of the byte array.

readLong

public long readLong(int iOffset,
                     boolean bLittleEndian)

Gets a long from the offset of the byte array.

readShort

public short readShort(int iOffset,
                       boolean bLittleEndian)

Gets a short from the offset of the byte array.

readShortAsInt

public int readShortAsInt(int iOffset,
                          boolean bLittleEndian)

Gets a short from the offset of the byte array.

readByte

public byte readByte(int iOffset)

Gets a byte from the offset of the byte array.

readBytes

public byte[] readBytes(int iOffset,
                        int iLen)

Gets a series of bytes from the byte array

writeBytes

public void writeBytes(byte[] yBytes)

Writes a series of bytes, in order.

Parameters

yBytes - the bytes

main

public static void main(String[] args)

Exerciser
