FixedArray
FixedArrayThe Array With a Fixed Size
for XP VX & ACE
Have you ever wanted to keep a Ruby Array at a certain size? Was it a pain you know where to prevent it from ever increasing its size or length?
Now you should not worry about that anymore!
Even so you can still clear its contents at any given time.

# Have you ever wanted to keep a Ruby Array at a certain size?
# Was it a pain you know where to prevent it from ever increasing
# its size or length?
# Now you should not worry about that anymore!
# Even so you can still clear its contents at any given time.
# Examples:
# ary = FixedArray.new(3)
# returns: []
# ary = FixedArray.new(3, :a, :b, :c, :d)
# returns: [:a, :b, :c]
class FixedArray < Array
def initialize(total, *args)
@maxsize = total
repeats = args.size > total ? total : args.size
repeats.times{ push(args.shift) }
end
def push(elem) size == @maxsize ? self : super(elem) end
def <<(elem) size == @maxsize ? self : super(elem) end
def unshift(elem) size == @maxsize ? self : super(elem) end
alias :>> :unshift
attr_accessor :maxsize
end
Script Calls
You may use p or print or puts or msgbox or msgbox_p script calls depending on your debugging needs and RM version.
Actually >> is an alias of the unshiftmethod.
Code:
array = FixedArray.new(3)
# returns: []
p array.size
# returns: 0
p array.maxsize
# returns: 3
array << :b << :c
# returns: [:b, :c]
array >> :a
# returns: [:a, :b, :c]
array = FixedArray.new(3, :a, :b, :c, :d)
# returns: [:a, :b, :c]
p array.size
# returns: 3
p array.maxsize
# returns: 3
