public abstract class RocksObject
extends AbstractImmutableNativeReference

RocksObject is an implementation of AbstractNativeReference which has an immutable and therefore thread-safe reference to the underlying native C++ RocksDB object.

RocksObject is the base-class of almost all RocksDB classes that have a pointer to some underlying native C++ rocksdb object.

The use of RocksObject should always be preferred over RocksMutableObject.
