Does this call work across objects? From the syntax it seems to only
register dependencies within the same object.
I'm basically wanting to define a property on B that says 'B
objectInKeyAtIndex: X' returns whatever 'A objectInKeyAtIndex: X' would
return, with the caveat that A.key is either static or updated as a
complete entity. The A objectInKeyAtIndex values are created on demand
based on a block of raw data (from an incoming data packet), which is why
I'm leery of creating a regular 'A setKey' accessor, since that's not
really what's happening.
