Method Detail

getInstance

Instance getInstance(NakedObject nakedObject)

Return an Instance of this Specification with respect to the provided NakedObject.

For example, if the Specification is a OneToOneAssociation, then is an Instance implementation representing the { NakedObject/ OneToOneAssociation } tuple.

Implementations are expected to use a double-dispatch back to the provided NakedObject (passing themselves as a parameter), using NakedObjectMM.getInstance(Specification).

Note: this method may throw an UnsupportedOperationException; see NakedObjectMM.getInstance(Specification) for details.
