All Implemented Interfaces:

DataInput, DataOutput
```
public final class RawDataBuffer
extends Object
implements DataOutput, DataInput
```
A RawDataBuffer is a dynamically growing byte array.

It implements DataOutput and DataInput to write or read data plus additional null-safe versions of the methods.

This class does not implement any synchronization nor bound checking for maximum performance.
Note that the UTF read/write methods are not compatible with the JDK implementation because they were modified to take advantage of the RawDataBuffer layout.
