public abstract class RocksCallbackObject
extends AbstractImmutableNativeReference

RocksCallbackObject is similar to RocksObject but varies in its construction as it is designed for Java objects which have functions which are called from C++ via JNI.

RocksCallbackObject is the base-class any RocksDB classes that acts as a callback from some underlying underlying native C++ rocksdb object.

The use of RocksObject should always be preferred over RocksCallbackObject if callbacks are not required.
