Calling a method of a Ruby Singleton without the reference of 'instance' -

-

i call method of singleton object without reference instance

singletonklass.my_method

instead of

singletonklass.instance.my_method

i've came solution (using method_missing in class):

require 'singleton'      class singletonklass   include singleton    def self.method_missing(method, *args, &block)     self.instance.send(method, *args)   end    def my_method      puts "hi there!!"   end end

is there drawback ? there better solution ? recommendation ?

thank you.

update:

my aim have module mixed-in singleton classes:

module noinstancesingleton    def method_missing(method, *args)       self.instance.send(method, *args)    end end

end use in class:

class singletonklass    include singleton    extend noinstancesingleton    def method1; end   def method2; end   ...   def methodn; end end

i want able directly call:

singletonklass.method1

using forwardable , def_delegators:

require 'singleton'     require 'forwardable'  class singletonklass   include singleton   class << self     extend forwardable     def_delegators :instance, :my_method   end    def my_method      puts "hi there!!"   end end  singletonklass.my_method

edit: if want include methods you've defined yourself, do

require 'singleton'     require 'forwardable'  class singletonklass   include singleton    def my_method      puts "hi there!!"   end    class << self     extend forwardable     def_delegators :instance, *singletonklass.instance_methods(false)   end end  singletonklass.my_method

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

(the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
