it's not completely clear to me what you're asking. julia isn't
particularly object oriented (i just checked and there's no mention of
objects or classes in the intro at http://julialang.org/)
having said that, you can store and modify (unless the type is immutable)
values in composite types. so, for example
julia> type State
x::Int
end
julia> function set(s::State, x::Int)
s.x = x
end
set (generic function with 1 method)
julia> function read(s::State)
return s.x
end
read (generic function with 1 method)
julia> s = State(12)
State(12)
julia> s.x
12
julia> s.x = 100
100
julia> s.x
100
julia> s
State(100)
julia> set(s, 32)
32
julia> s
State(32)
julia> read(s)
32
maybe that helps? obviously set and read are trivial to do directly on the
instance, but you could imagine more complex functions.
