Eventmachine talk - Aug 2006 - Deferrable question

Looking at your tcptest class I can''t figure out how you instantiate
the class, add callbacks, then make the connection.  Your method that
makes the connection (self.test) is private so it can''t be called
outside the class either.  I''m probably missing something really
basic, but it''s eluding me..

Chris, here''s an example of how to use TcpTester. It''s
actually about
as simple as can be, but very nonobvious from the code. If you''ve ever
written for Python''s Twisted, this code sample will make sense
instantly.

#---------------------------------
require ''rubygems''
require ''eventmachine''

pr = proc {
  tester = EventMachine::Protocols::TcpConnectTester.test(
"www.cisco.com", 443 )
  tester.callback {|t| "Connection in #{t} seconds"}
  tester.errback {|t| "Connection failed in #{t} seconds"}
}

EventMachine.run { pr.call }
#---------------------------------

I''ll let you play with this while I take a few more minutes to write
another email that explains it better.
