NSManagedObjectContext is not listed in the Cocoa Bindings
Reference [1]. Is this really a "binding", or is it something
else? The documentation for binding NSArrayController
'managedObjectContext' in [1] calls it "registered with".
It's not clear what this means.
Bindings are bindings.
Well, I would say that the code I entered above is not a binding
because it does not, and could not, invoke
bind:toObject:withKeyPath:options
It's again not clear what this means.
The code you wrote above is, obviously, not a binding -- you're
setting the managed object context directly using an accessor method.
You can, however, bind the 'managedObjectContext' binding of
controllers -- it is common(*), for example, in a document-based
application to bind it to [TheDocument].managedObjectContext.
If you wanted to do this in, say, the implementation of
windowControllerDidLoadNib in a subclass of NSPersistentDocument it
would look like:
