Is it possible to get all subclasses of given class in php? ...
Hey guys, I am hoping someone can explain about subclasses accessing variables from the super class. I found that the subclass can only access variables which are set in the constructor of the super class. Is there any way around this? package Character { import flash.display.MovieClip; public class Character extends MovieClip { ...
Do the methods of a member variable have access to other private member variables within the same class? I have in mind a functor member variable. Can a pointer to a private member variable be dereferenced and assigned to, outside of the class? What about in the method of another member variable? Maybe something like class A { some...

Hi, I was wondering how the UILabel that displays the website's title in Mobile Safari is created? It's obviously some kind of a subclass and I've attempted to copy it by using my own subclass,but it just doesn't look the same. I also don't know which font they're using :/ Could anyone help me out please? :) here's my class: CGSize s...
I don't really get JavaScript prototyping. Take this code, for instance: function Class(asdf) { if(typeof(asdf) == 'undefined') { } else { this.asdf = asdf; } } Class.prototype.asdf = "default_asdf"; Class.prototype.asdf2 = []; Class.prototype.change_asdf = function() { this.asdf = "changed_asdf"; this.asdf2.push("changed_asdf2")...
I would like to ask what is the good practice on using anonymous classes vs. named inner classes? I am writing an Android application, which includes many UI elements (buttons, text fields, etc). For many of them I need some kind of listeners, so in onCreate of the application I have bunch of quite small anonymous classes like: someBu...

Hey all, So I subclassed UIViewController and in the nib I have a UIView, and in it a tableview. It is my understanding that both UIViewController and UIView are subclasses of UIResponder, so they should receive the - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event method. However, this is not the case, and my view contr...
As an example, when I'm using an NSMutableDictionary, I know it inherits all the methods of NSDictionary, but how can I know/trust that it has overridden the behavior of those methods if I want to use NSDictionary methods (such as +dictionaryWithObjectsAndKeys) to create my mutable dictionary instance? More generally, is it the Framewo...
I was surprised to to learn that a class variable of a subclass can't access a class variable of the parent without specifically indicating the class name of the parent: >>> class A(object): ... x = 0 ... >>> class B(A): ... y = x+1 ... Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<stdin>", ...
Ok... in C++ you can new up a subclass from a static method in the base class with 'new this()' because in a static method, 'this' refers to the class, not the instance. That was a pretty damn cool find when I first found it and I've used it often. However, in C# that doesn't work. Damn! So... anyone know how I can 'new' up a subclass...

This may be a ridiculous Java question about exception handling, but I have a UI actor (an Android Activity) that is requesting services from my subclass of ContentProvider. The subclass wants to throw some exceptions when sd-card is full, sd-card is missing, network i/o errros, etc. However, when I code the CP-subclass to throw my exc...
If both ProductsController and CategoriesController both inherit from GenericController, what is a good way to get the string products in the base class when the URL is pointing to the Products controller? (in this case, the base class's index action is doing things that would need to use the string products to query the database) self...
