Class Cloner

java.lang.Object

io.github.ai4ci.util.Cloner

public class Cloner
extends Object

Utility for making deep copies (vs. clone()'s shallow copies) of objects. Objects are first serialized and then deserialized. Error checking is fairly minimal in this implementation. If an object is encountered that cannot be serialized (or that references an object that cannot be serialized) an error is printed to System.err and null is returned. Depending on your specific application, it might make more sense to have copy(...) re-throw the exception. from: https://javatechniques.com/blog/faster-deep-copies-of-java-objects/
