hanks Bob! the example helped a lot.

Tim, i want to change the behavior of some methods (at runtime, based on the user's decision).

for example, if a method of class A contains the comment:
"hello, this is a comment"

than if B inherits from A, this method wouldn't be inherited (an attempt to call this method from an object of type B would cause an exception to be thrown).

the reason i'm using a comment is that it doesn't affect the code.

is there a simple way to add a code to a method?

for example, to add "this is a comment" to the end of the code?

You'll get better advice if you expand upon what you want & why; what is the real problem you are trying to solve here?

If, for example you're simply wanting to programatically find all senders of a particular message then the code is already there -
take a look at SystemNavigation>allCallsOn:fromBehaviors:sorted: to see how to scan all the methods implemented by a list of behaviours (ie classes or metaclasses) for sends of a particular message, including ones that are special cases.
If you already know which class and method you want to look at then examine Behavior>whichSelectorsReferTo:specialByte:thorough: to see how the system does it.

Or are you wanting to look for particular fragments of code with some sort of text based pattern matching? Or…?
