How do you make a deep copy of an object?

Question

It\'s a bit difficult to implement a deep object copy function. What steps you take to ensure the original object and the cloned one share no reference?

Answer 1

You can use a library that has a simple API, and performs relatively fast cloning with reflection (should be faster than serialization methods).

Cloner cloner = new Cloner();

MyClass clone = cloner.deepClone(o);
// clone is a deep-clone of o
