Constructor Detail

### ByteConversion

    public ByteConversion()

Method Detail

### byteToInt

    public static final int byteToInt(byte[] data,
                                      int start)

  Read an integer value from the specified byte array, starting at start.

### byteToLong

    public static final long byteToLong(byte[] data,
                                        int start)

  Read a long value from the specified byte array, starting at start.

### byteToShort

    public static final short byteToShort(byte[] data,
                                          int start)

  Read a short value from the specified byte array, starting at start.

### intToByte

    public static final byte[] intToByte(int v,
                                         byte[] data,
                                         int start)

  Write an int value to the specified byte array. The first byte is written into the location specified by start.

  Parameters:
    `v` - the value
    `data` - the byte array to write into
    `start` - the offset
  Returns:
    the byte array

### longToByte

    public static final byte[] longToByte(long v,
                                          byte[] data,
                                          int start)

  Write a long value to the specified byte array. The first byte is written into the location specified by start.

  Parameters:
    `v` - the value
    `data` - the byte array to write into
    `start` - the offset
  Returns:
    the byte array

### longToByte

    public static final byte[] longToByte(long v)

  Write an int value to a newly allocated byte array.

  Parameters:
    `v` - the value
  Returns:
    the byte array

### shortToByte

    public static final byte[] shortToByte(short v,
                                           byte[] data,
                                           int start)

  Write a short value to the specified byte array. The first byte is written into the location specified by start.

  Parameters:
    `v` - the value
    `data` - the byte array to write into
    `start` - the offset
  Returns:
    the byte array

### shortToByte

    public static final byte[] shortToByte(short v)

  Write a short value to a newly allocated byte array.

  Parameters:
    `v` - the value
  Returns:
    the byte array
