I would like to know if it’s possible to define iterators like each for
a
class you have written ?
Is it also possible to write methods that can have the following
behavior/usage:
object.method do |var|
something
end

Hi,
see http://www.rubycentral.com/book/tut_containers.html
look for “blocks and iterators”

Sure. And if you define each and include Enumerator, you get all sorts
of methods along with it (find, select, inject, etc.).

Yes; such a method is called an iterator
def object.m
yield 10
end
object.m do |var|
# var is equal to 10
end
Have a look in any Ruby tutorial book for more.
