module Rapporteur
# Manages a list of checks.
#
# The goals of this object are to store and return the check objects given to
# it in the same order they were given (in Ruby 1.8 and newer). And, to
# ensure that the same check is not added twice to be run.
#
# Previously, a native Ruby Set was used. However, Sets do not guarantee
# order, particularly in Ruby 1.8. A simple Array is possible, but loses the
# uniqueness constraint of the objects added.
#
class CheckList
# Public: Returns a new, empty CheckList instance.
#
def initialize
@list = Array.new
end
# Public: Add a new check to the list.
#
# Returns the CheckList instance.
#
def add(check)
@list << check unless @list.include?(check)
self
end
# Public: Empties all checks from the list. This functionally resets the
# list to an initial state.
#
# Returns the CheckList instance.
#
def clear
@list.clear
self
end
# Public: Iterates over all of the contained objects and yields them out,
# individually.
#
# Returns the CheckList instance.
#
def each(&block)
@list.each(&block)
self
end
# Public: Returns true if the list is empty.
#
def empty?
@list.empty?
end
# Public: Returns the objects in the list in an Array.
#
def to_a
@list.dup
end
end
