### readShort

    public short readShort()

  Description copied from class: `DataInput`
  Reads two bytes and returns a short.

  Overrides:
    `readShort` in class `DataInput`
  See Also:
    `DataOutput.writeByte(byte)`

### readInt

    public int readInt()

  Description copied from class: `DataInput`
  Reads four bytes and returns an int.

  Overrides:
    `readInt` in class `DataInput`
  See Also:
    `DataOutput.writeInt(int)`

### readLong

    public long readLong()

  Description copied from class: `DataInput`
  Reads eight bytes and returns a long.

  Overrides:
    `readLong` in class `DataInput`
  See Also:
    `DataOutput.writeLong(long)`

### readVInt

    public int readVInt()

  Description copied from class: `DataInput`
  Reads an int stored in variable-length format. Reads between one and five bytes. Smaller values take fewer bytes. Negative numbers are not supported.

  The format is described further in `DataOutput.writeVInt(int)`.

  Overrides:
    `readVInt` in class `DataInput`
  See Also:
    `DataOutput.writeVInt(int)`

### readVLong

    public long readVLong()

  Description copied from class: `DataInput`
  Reads a long stored in variable-length format. Reads between one and nine bytes. Smaller values take fewer bytes. Negative numbers are not supported.

  The format is described further in `DataOutput.writeVInt(int)`.

  Overrides:
    `readVLong` in class `DataInput`
  See Also:
    `DataOutput.writeVLong(long)`

### readByte

    public byte readByte()

  Description copied from class: `DataInput`
  Reads and returns a single byte.

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

### readBytes

    public void readBytes(byte[] b,
                          int offset,
                          int len)

  Description copied from class: `DataInput`
  Reads a specified number of bytes into an array at the specified offset.

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