public class UnsafeByteBufferInput
extends ByteBufferInput
```
A ByteBufferInput that reads data from direct ByteBuffer (off-heap memory) using sun.misc.Unsafe. Multi-byte primitive types use native byte order, so the native byte order on different computers which read and write the data must be the same.
Not available on all JVMs. Util.unsafe can be checked before using this class.
This class may be much faster when Input.setVariableLengthEncoding(boolean) is false.
