Where is initialize originally defined?

Hi to everyone,

could you please tell me where the initialize method is originally defined?

I thought it should be defined in Object, Class, or Module. But on
http://www.rubycentral.com/book/builtins.html I can’t see it anywhere.

Please enlighten me. Thanks!
Markus

private method of Object
Class, Module (and Array, ...) redefine it

Thanks!

I wonder where I can find a downloadable documentation in which all
methods are visible. And I wonder why the document on RubyCentral that I
mentioned does list for example the method method_missing (which seems
to be private as well) but doesn’t list initialize.

Thanks for your patient help!

Object#initialize is a private method defined in Object

method_missing is a global function, i.e. a module function of Kernel.

The pickaxe describe only method defined in Kernel, and this explain why
Object#initialize is not described (and this must be the only exception)

I’ll probably add it in for 1.8; I hadn’t done it before because it
didn’t seem to fit there, but now that we have allocation as a function
it shou;d go in for completeness.
