Class DeepCopy

  • public class DeepCopy
extends java.lang.Object
    from http://javatechniques.com/blog/faster-deep-copies-of-java-objects/, see also https://stackoverflow.com/a/64066 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.
