Defining a method []=

ruby-talk
1

I have used a method of [] with "def method[](string)". But I can't
figure out how to use[]=.

An array works with []= such as array['string1'] = 'string2' so how
would I write a method like that for my own class?

Much the same way -- it will have two parameters.

   class MyClass
     def =(index,assigned)
       # ...whatever...
     end
   end

Make sense?

def method=(index, value)
...
end

You define a method called "=".

class Foo
def = key, value
puts "Setting key '#{key}' to '#{value}'"
end

f = Foo.new
f[:hello] = "world"

# Setting key 'hello' to 'world'
