Is there a sure-fire way to know when it is necessary to call super in an 
override?

Sample code shows that calling super is necessary for methods such as

-(id)init


- (void)windowControllerDidLoadNib


but not for


(NSData *)dataOfType


(BOOL)readFromData


How can you know for sure?


This question occurred to me recently when I realized that my implementation of


(NSApplicationTerminateReply)applicationShouldTerminate


did not call super and I was wondering whether I should.  Currently, I just 
clean up and return NSTerminateNow.


Thanks for any reply.
