less than sign for inheritance in classes

[Smart RoR]

Hello:

Where in Ruby is the less than sign for inheritance in classes defined?

class A < B


The < here that is.


Thanks.

I'm not sure if I understand your question, but '<' is just syntax when
used in a class definition. In this context, it is not an operator and so
there is no method associated with its use in this context.

Every operator is a method in ruby....

like 1 - 1 = 0 here - is a method.

That is my understanding....

And is the "=" too a method? Can you redefine it?

If you want to find out if somebody is inheriting your class, implement
'MyClass.inherited' (it's a hook).

Let me try again. The '<' in a class definition
is not an operator and so doesn't have an
associated method. It looks like an operator
but is not parsed or interpreted as an operator
when used in a class definition.

Thanks. But in that case where is the < handled to identify
inheritance....
That is the core handling as to where is this implemented in ruby core.

That would be deep inside parse.y -- the grammar file for the parser.
Look for the superclass non-terminal (about 4100 lines or so into the
file).
