The SemanticKey class helps to ensure the uniqueness constraint on object's identity. This is accomplished by storing persistently a unique string representing the identity.

Use the newSemanticKey static factory method(s), not the SemanticKey constructor, to construct instances of this class. Instances must be constructed using the static factory(s), in order to ensure proper initialization of the instance.
