### ByteArrayDataOutput

    public ByteArrayDataOutput(byte[] bytes)

### ByteArrayDataOutput

    public ByteArrayDataOutput(byte[] bytes,
                               int offset,
                               int len)

### ByteArrayDataOutput

    public ByteArrayDataOutput()

Method Detail

### reset

    public void reset(byte[] bytes)

### reset

    public void reset(byte[] bytes,
                      int offset,
                      int len)

### getPosition

    public int getPosition()

### writeByte

    public void writeByte(byte b)

  Description copied from class: `DataOutput`
  Writes a single byte.

  The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.

  Specified by:
    `writeByte` in class `DataOutput`
  See Also:
    `DataInput.readByte()`

### writeBytes

    public void writeBytes(byte[] b,
                           int offset,
                           int length)

  Description copied from class: `DataOutput`
  Writes an array of bytes.

  Specified by:
    `writeBytes` in class `DataOutput`
  Parameters:
    `b` - the bytes to write
    `offset` - the offset in the byte array
    `length` - the number of bytes to write
  See Also:
    `DataInput.readBytes(byte[],int,int)`
