```
public void skipBytes(long count)

    Description copied from class: DataInput
    
    Skip over numBytes bytes. This method may skip bytes in whatever way is most optimal, and may not have the same behavior as reading the skipped bytes. In general, negative numBytes are not supported.
    
    Specified by:
    
    skipBytes in class DataInput
  - readShort
```
public short readShort()
```
    Description copied from class: DataInput
    
    Reads two bytes and returns a short (LE byte order).
    
    Overrides:
    
    readShort in class DataInput
    
    See Also:
    
    DataOutput.writeShort(short), BitUtil.VH_LE_SHORT
  - readInt
```
public int readInt()
```
    Description copied from class: DataInput
    
    Reads four bytes and returns an int (LE byte order).

    See Also:
    
    DataOutput.writeInt(int), BitUtil.VH_LE_INT
  - readLong
```
public long readLong()
```
    Description copied from class: DataInput
    
    Reads eight bytes and returns a long (LE byte order).
    
    Overrides:
    
    readLong in class DataInput
    
    See Also:
    
    DataOutput.writeLong(long), BitUtil.VH_LE_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 supported, but should be avoided.
    The format is described further in DataOutput.writeVInt(int).
    
    Overrides:
    
    readVInt in class DataInput

  - 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

  - readByte
```
public byte readByte()
```
    Description copied from class: DataInput
    
    Reads and returns a single byte.

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
