#name

by Ben Coman

What is the purpose of the #name method in the system? How integral/important is this method and what are the dangers of overriding it? I am getting tired of auto creating accessors and getting a #name1 method due to a clash that I happened to very commonly have 'name' as an instance variable. I have so far been changing my 'name' instance variables to 'myName' to avoid the clash because I am not comfortable with my understanding of how it ties in - but its time I tried harder to understand. cheers -ben

OK I fixed it. For some reason the session was opened but and I coudn't issue NativeBoost initilize, I just setted the Current variable to nil and the session was reinitialized at the next call to NativeBoost.

Hi Igor, Promise the last question today. What can be causing that issuing: > "NativeBoost forCurrentPlatform callbackCounterAddress. " returns "nil" ?. In the trunk 1.8 is OK and it returns "@16r282000" in my case.

Ok, but happens that #value: uses #fieldAt: was inherited from NBExternalStructure, which is no longer in the hierarchy. But I understand that it will no longer work with the change I made, any idea?

No, it should be NBExternalAddress value: addr because method should answer an instance of NBExternalAddress not integer.
