ByteArrayDataOutputStream (JGroups 3.6.10.Final API)

java.lang.Object
- org.jgroups.util.ByteArrayDataOutputStream

All Implemented Interfaces:

DataOutput
```
public class ByteArrayDataOutputStream
extends Object
implements DataOutput
```
Implements DataOutput over a byte[] buffer. The byte[] buffer expands when needed; however, it doesn't double but only expands minimally, to accommodate the additional data. It is therefore recommended to always size the buffer to the actual number of bytes needed. This class is not thread safe.
