# module Enumerable

This is a simple reimplementation of the core Enumerable module to allow the methods to take and pass-on arbitrary arguments to the underlying each call. This library uses Enumerator and scans Enumerable so it can alwasy stay in sync.

NOTE Any Enumerable method with a negative arity cannot do pass arguments due to ambiguity in the argument count. So the methods inject and zip do NOT work this way, but simply work as they do in Enumerable. The method find (and detect) though has been made to work by removing its rarely used optional parameter and providing instead an optional keyword parameter (:ifnone => …). Please keep these difference in mind.

    require 'enumargs'

    class T
      include Enumerable::Arguments
      def initialize(arr)
        @arr = arr
      end
      def each(n)
        arr.each{ |e| yield(e+n) }
      end
    end

    t = T.new([1,2,3])
    t.collect(4)
    #=> [5,6,7]

### Public Instance Methods

threaded_map() { || ... } click to toggle source

Like Enumerable#map but each iteration is processed via a separate thread.

    def threaded_map #:yield:
      map{ |e| Thread.new(e){ |t| yield(t) } }.map{ |t| t.value }
    end

threaded_map_send(meth, *args, &block) click to toggle source

Like Enumerable#map_send but each iteration is processed via a separate thread.

    def threaded_map_send(meth, *args, &block)
      map{ |e| Thread.new(e){ |t| t.send(meth, *args, &block) } }.map{ |t| t.value }
    end
