```
public void readFields(DataInput in)
                throws IOException
```
    Description copied from interface: Writable
    
    Deserialize the fields of this object from in.
    For efficiency, implementations should attempt to re-use storage in the existing object where possible.
    
    Specified by:
    
    readFields in interface Writable
    
    Parameters:
    
    in - DataInput to deseriablize this object from.
    
    Throws:
    
    IOException
  - writeType
```
public void writeType(DataOutput out)
               throws IOException
```
    Description copied from interface: Writable
    
    Write the type (a single short value) to the DataOutput. See WritableFactory for details.
    
    Specified by:
    
    writeType in interface Writable
    
    Parameters:
    
    out - DataOutput to write to
    
    Throws:
    
    IOException - For errors during writing
  - write
```
public void write(DataOutput out)
           throws IOException
```
    Description copied from interface: Writable
    
    Serialize the fields of this object to out.
    
    Specified by:
    
    write in interface Writable
    
    Parameters:
    
    out - DataOuput to serialize this object into.

    toDouble in interface Writable
  - toFloat
```
public float toFloat()
```
    Description copied from interface: Writable
