I run into the following situation: I have to pre-process some data and
then use varaibles to represent these processed data. I also want to
use these variables in many places but I do not want to turn all of them
into class instance variables. (@variable, that is) and I don’t want to
pass them as parameters for the method ( so I could use anything I want
without changing the method declaration)
What are the alternatives?
Thanks.

Example:
class Something
def initialize(v1, v2, data)
# blah, blah, blah
end
def act(data)
#preprocess the data
#d1, d2, d3 and so on is available now
end
def use1()
#use some of the d’s ( it can be d2, d7 )
end
def use2()
#use some of the d’s (it can be d1, d4 )
end
def use3()
# and so on…
end
end
Would an array do what you want?
def act(data)
# Creates the array ‘d’
# d[0], d[1] and so on is available now
end
def use1()
#use some of the d’s ( it can be d[2], d[7] )
end
I think that you do have to use the instance ‘@d’. ‘d’ Is local to the
current method (if I understand Ruby scope correctly).
Hope that helps.
