Example usage for org.apache.commons.lang SerializationUtils clone

Introduction

In this page you can find the example usage for org.apache.commons.lang SerializationUtils clone.

Prototype

public static Object clone(Serializable object)

Document

Deep clone an Object using serialization.

This is many times slower than writing clone methods by hand on all objects in your object graph.
