How to Call a static method?

Daniel Völkerts

10/3/2006 2:06:00 PM

Hi there, after I searched the ruby-doc.org site I couldn't find a hint
how to call a class method on different classes.

I've a helper class which parses a text input and which should either call

Role.something or

Organisation.anotherthing

depening which parameter was passed.

Please give a little hint to proceed. Thanks a lot...

Just do it
if condition
Role.something
else
Organisation.anotherthing
end

Nothing special.

class Test
def self.test
puts "The huge test...OF DOOM!"
end
end
Test.test # => The huge test...OF DOOM!

Test.test isn't really a static method, but a singleton method on
Test. Then just do a test in your method:

def call_one_or_the_other(x)
case x
when SomeClass
Role.something
when OtherClass
Organisation.anotherthing
end
end

Okay, misleading question.

What if I like to call the classes dynamically e.g.

def mymethod(class,method)
call(class,method,options)
end

?

Where call is the Ruby function I'm looking for.

greetings,

Class.send(:method, *options) or

const_get('Class').send(:method, *options)

possibly

const_get('Class').send(:method, *options, &block) but i'm not sure
with this one.

Great const_get('Classname').send is what I'm looking for. TIA!

I think it's his only recording of any Chopin ballade

Yes, Miguel, but one 8' piece is not exactly what I was thinking of,
you know.

The piano repertoire is enormous; AW recorded so little of it in the
end. This is the pity.

And no more will come from his hands today.

Right. And he surely played them all. What about Brahms? Liszt?
Schubert? Schumann? And so on?

I would like more Haydn to be transferred. Steve, did you grok that?

Did he play much Mozart TD? I have a PC21 (Giulini and VSO) with an
extraordinary cadenza, but that's all.
