ByteBufferVolSingle

Volume
- org.mapdb.volume.ByteBufferVolSingle

Direct Known Subclasses:

ByteBufferMemoryVolSingle, MappedFileVolSingle
```
public class ByteBufferVolSingle
extends Volume
```
Abstract Volume over single ByteBuffer, maximal size is 2GB (32bit limit). It leaves ByteBufferVol details (allocation, disposal) on subclasses. Most methods are final for better performance (JIT compiler can inline those).
