All Implemented Interfaces:

Copier

public class JavaSerializationCopier
extends AbstractCopier<byte[]>

A strategy that uses Java serialization if a fast path approach is not applicable.

Beware that native serialization is slow and is provided for completeness. In practice, it is recommended that a higher performance alternative is used, which is provided by numerous external libraries.
