Class DeepCopy

java.lang.Object

sonia.scm.io.DeepCopy

public final class DeepCopy
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.
