Class PipedDeepCopy

java.lang.Object
  org.telscenter.pas.util.PipedDeepCopy

public class PipedDeepCopy
extends java.lang.Object

Utility for making deep copies (vs. clone()'s shallow copies) of objects in a memory efficient way. Objects are serialized in the calling thread and de-serialized in another thread. 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. http://javatechniques.com/public/java/docs/basics/low-memory-deep-copy.html
