• Java method missing (ala Ruby) for decorating?

  - by cibercitizen1

  Is there any technique available in Java for intercepting messages (method calls) like the method_missing technique in Ruby? This would allow coding decorators and proxies very easily, like in Ruby: :Client p:Proxy im:Implementation ------- ---------- ----------------- p.foo() -------> method_missing() do_something im.foo() ------------------> do_foo p.bar() --------> method_missing() do_something_more im.bar() -------------------> do_bar (Note: Proxy only has one method: method_missing())

• "Add Controller" / "Add View" in a hybrid MVC/WebForms ASP.NET application

  - by orip

  I have an existing WebForms project to which I'm adding MVC pages. I created an MVC project and copied the project type guids. It works fine, but I can't get Visual Studio to display the "Add Controller" or "Add View" wizards on my controllers and views directories (they're not /Controllers and /Views, they're in /Foo/Controllers and /Foo/Views). Is it possible to enable the wizards?

• Move from *this in an rvalue method?

  - by FredOverflow

  In C++0x, methods can be overloaded on whether or not the expression that denotes the object on which the method is called is an lvalue or an rvalue. If I return *this from a method called via an rvalue, do I need to explicitly move from *this or not? Foo Foo::method() && { return std::move(*this); // Is this move required or not? } Unfortunately, I can't simply test this on my compiler since g++ does not support this feature yet :(

  - by tzeldin88

  On Admin Edit Posts (edit.php), how can I filter for a Custom Taxonomy and see posts of ANY status, not just Published? For example, say I have a Custom Taxonomy "Color"... These queries find posts of ANY status: edit.php?category_name=foo edit.php?author=3 edit.php?tag=foo And this query works correctly: edit.php?color=red&post_status=draft But this query finds ONLY Published posts: edit.php?color=red

• Berkeley DB: btree prefix comparison for directory-like keys?

  - by Mark Harrison

  I'm going to index a BDB with keys that look a lot like directory paths ('/foo/bar', '/foo/baz', etc, with levels of slashes generally < 10). Does anybody have any experience with using a Btree prefix comparison routine[1] for this? Are the savings worthwhile? Any references to experience papers on this subject?

• Why .data() function of jQuery is better to prevent memory leaks?

  - by burak ozdogan

  Hi, Regarding to jQuery utility function jQuery.data() the online documentation says: "The jQuery.data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. " Why to use: document.body.foo = 52; can result a memory leak -or in what conditions- so that I should use jQuery.data(document.body, 'foo', 52); Should I ALWAYS prefer .data() instead of using expandos in any case? (I would appreciate if you can provide an example to compare the differences) Thanks, burak ozdogan

• replacing toString using Groovy metaprogramming

  - by Don

  In the following Groovy snippet, I attempt to replace both the hashCode and toString methods String.metaClass.toString = {-> "override" } String.metaClass.hashCode = {-> 22 } But when I test it out, only the replacement of hashCode works String s = "foo" println s.hashCode() // prints 22 println s.toString() // prints "foo" Is toString somehow a special case (possibly for security reasons)?

• Generic Rails Route Representation?

  - by Flemish Bee Cycle

  Given one or more instances of a model (AR or DM, whatever). Is it possible to generate the route in the requirement form, by which I mean "/foos/:id" Given the route: resource :foo do resource :bar end generate_route_method [@foo,@bar] - "/foos/:id/bars/:id" I'm not talking about #foos_path or #polymorphic_path, rather, literally generating the string containing the wildcard components (i.e ":id"), the same as it would appear as if you did "rake routes".
