Subject: Class Method Definition - Unrecognized Syntax

I am studying the source code contained in session.rb in an effort to
understand how it works.  I am encountering various instances of syntax
that I don't understand.  I'm sure Google would be my friend if I knew
what terms to use as search criteria. I'm hoping that I can post a few
of them here for clarification without being overly burdensome.

The first strange syntax that I encountered was what was apparently a
class definition in the Session class:  Here's the syntax:

    def Session::create_new_id

In this case the separator between the identity of the class and the
name of the method is a double colon rather than the usual period.
What is the significance of using a double-colon as a separator?

Thanks for any input.
