public interface Copyable<E>

The Copyable interface defines a method for returning a copy of an object. Individual implementations are left to determine if the copy is deep or shallow. However, a preference is for deep copies.This interface acts an alternative to Java's clone method providing a generic return type. To aid possible implementations, a static deepCopy method is provided that uses Java serialization to perform a deep copy of an object.
