The object for the specified ID.
If the object is not registered in the context, it may be fetched or returned as a fault. This method always returns an object. The data in the persistent store represented by
objectID is assumed to exist—if it does not, the returned object throws an exception when you access any property (that is, when the fault is fired). The benefit of this behavior is that it allows you to create and use faults, then create the underlying data later or in a separate context.

Passes a request to the persistent store without affecting the contents of the managed object context and returns a persistent store result.
