NSManagedObject
Extensions
Declared in: nu/coredata.nu
ActiveRecord-style extensions to NSManagedObject.
These are most useful for entity-specific subclasses of NSManagedObject.
When an entity is looked up by name, it must be defined in the application delegate's managed object model.
Methods
Create an object for the entity with the same name as this class.

objectWithIdentifier: |
(id) identifier |
Get an object with a specified identifier and the entity with the same name as this class.
This method allows an object to be associated with a short integer identifier.
Identifiers are represented as NSStrings.
It works by extracting the identifier from the object's URIRepresentation.
If the implementation of URIRepresentation changes, this will break.
