Class variables

Question

I got bored of searching hahaha Can anybody tell me the best or just some way to declare a variable that can be used in any method of the class? I have 4 arrays in a class and 3 methods. I want to be able to use those 4 arrays without having to declare them in each method! Thanks! :D

Answer 1

You could just use global scope, putting a $ before your variable name.

Answer 2

I believe the example you gave is right, but I'm not a pro in Ruby either.

Answer 3

Ok, thanks man! Now I have a starting point to try :)

PD: I'm amazed how fast people answer questions here hahaha

Answer 4

Global vars are a bad practice most times. I recommend you to uset instance variables for the arrays in the initialize method. If your methods are class methods, use class variables instead.

Answer 5

you mean something like:
def class SomeClass
$variable

def some_method
#use the variable here
end

def some_other_method
#and here too
end
end
??

Answer 6

ooh wait, or the global have to be declare before the class? I don't remember very well, I'm new on this, sorry :(
