WriteBuffer (Apache Tomcat 8.5.61 API Documentation)

```
public class WriteBuffer
extends Object
```
Provides an expandable set of buffers for writes. Non-blocking writes can be of any size and may not be able to be written immediately or wholly contained in the buffer used to perform the writes to the next layer. This class provides a buffering capability to allow such writes to return immediately and also allows for the user provided buffers to be re-used / recycled as required.
