Examples of org.apache.cayenne.ObjectContext.localObject()

org.apache.cayenne.ObjectContext.localObject()
Returns an object local to this ObjectContext and matching the ObjectId. If prototype is not null, local object is refreshed with the prototype values.
This method can do both "mapping" (i.e. finding an object with the same id in this context) and "synchronization" (i.e. updating the state of the found object with the state of the prototype object).
