Interface Identifiable

public interface Identifiable

An object that has an identity number.

Objects that implement this interface have an ID number. This interface makes no promises about the uniqueness of that number. Classes that manage Identifiable objects are expected to deal with issues of uniqueness. For example, a repository of Foo objects would be expected to ensure that each of its Foo instances had unique IDs.

The motivation for this class was to aid persistence mechanisms.
