Ruby Class and Object singleton - get access -

-

i learning ruby singletons , have misunderstanding such code:

class myclass   def self.class_singleton_mymethod   end end  class_singleton = class << myclass   self end  puts class_singleton.methods.grep(/mymethod/)  # => []   obj = myclass.new  def obj.object_singleton_mymethod end  object_singleton = class << obj   self end  puts object_singleton.methods.grep(/mymethod/) # => class_singleton_mymethod

why class_singleton not contains class's class method , object_singleton instead of object's singleton method contains class's class method?

i think have notion of methods , instance_methods mixed up. if replace instances of methods instance_methods, see results expect.

instance_methods used enumerate methods class's instances have. methods used enumerate methods object has. (class objects objects too, , have own methods new not instance methods.

for example, string#slice instance method; can call slice on string instances. on other hand, string.new method on string itself; don't call new on string instances, can call string.new (i.e., on string class object itself) create new string.)

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...

c# - How to set Z index when using WPF DrawingContext? -

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.

c# - Cloning WPF controls and object hierarchies -

i have problems cloning object hierarchie. it's toolkit modelling applications, toolbox contains class instances prototypes. i'm having hard time cloning these :) the following code shows problem: public abstract class shape { protected list<uielement> elements; private canvas canvas; ... public canvas getcanvas() { ... }; } public class movableshape : shape { protected ... propertya; private ... propertyxy; ... } public abstract class abstractlayout : movableshape, ... { ... } public class somelayoutclass : abstractlayout, ... { ... } public class acontainingclass { somelayoutclass layout { get; set; } ... } when insert object of acontainingclass project worksheet, should cloned. far tried manual cloning (which fails because of private fields in base classes) , binary serialization ( binaryformatter , memorystreams ). the first approach lacks way call base.clone() method (or wrong?), latter not work because uielement s aren't...
