I'm relatively new to using oop in Javascript, and I'm wondering what the best practice is for private methods. Right now, I'm using mootools to create my classes and I'm simulating private methods by prefixing them with an underscore and forcing myself not to call the method outside of the class. So my class looks like: var Notifier ...
I have two classes, point and pixel: class point { public: point(int x, int y) : x(x), y(y) { }; private: int x, y; } template <class T> class pixel : public point { public: pixel(int x, int y, T val) : point(x, y), val(val) { }; private: T val; } Now here's my problem. I want to make ...
I'd like to be able to dynamically create an instance method within a class' constructor like so: class Foo{ function __construct() { $code = 'print hi;'; $sayHi = create_function( '', $code); print "$sayHi"; //prints lambda_2 print $sayHi(); // prints 'hi' $this->sayHi = $sayHi; } } $f = new Foo; ...
The following code: class House: links = [] class Link: pass class Villa(House): pass if __name__ == '__main__': house = House() villa = Villa() link = Link() house.links.append(link) print house.links print villa.links results in this output: [<__main__.Link instance at 0xb65a4b0c>] [<__main_...
I'm developing a web system using regular PHP. This was my first experience with PHP sothe code is not legible nor clean. It mixes some many html code with PHP. I'd say I have already done half of the code. What are the real advantages of the Object-oriented PHP. The website is about books and book authors, using mysql and apache. So it...
I am developing on a system that is a bit difficult to work with. It is 99% undocumented, does not follow best practices and is fairly difficult to understand (globals galore, methods spanning 50 lines, eval abuse, etc.). Unfortunately, I am fairly new to the code base and I need to add functionality. I am sure there is code in there th...
I have a class that's similar to the following: class Person { private static $_sqlData; public function __construct($id) { if (!self::$_sqlData) { self::$_sqlData = // GET THE DB STUFF } } public function getName() { return self::$_sqlData['name']; } } This has bee...
object orientation was the last big paradigm shift I remember. What do you think will be the next big thing in programming paradigms and programming in general? Edit: I was actually listening to Jaron Lanier interview and he was talking about how in the future we would stop worrying idiosyncrasies and the little tidbits about programmi...

Hi. I'm not very used to javascript's prototyping syntax so this might be very simple. function MyClass(){ this.init = function(input){ this.input.onkeyup = function(){ this.change(); } } } Obviously I've left some things out here, but this.input refers to an HTML input element. The problem here is that this...

This is a fairly lengthy (not overly complex) design question so please bear with me. I'm trying to implement a person/role management system with POJOs and JPA. I'm fairly new to ORM and this is mostly a mapping problem. I've got this working as POJOs and am comfortable with the caller-level API, but would now like to map it to a datab...
This is more of an architecture/best practices question than anything else, so please feel free to add your two cents. I know i stated status in the title, but this goes for any basic property of an object. I think the account example below will help demonstrate my question a little better than status. Here is a sample Account object: ...
Writing some Objective-C in one method, I call +alloc, then -init to set up an object. object = [[MyClass alloc] init]; [object useFor:whatever]; The next few lines of code use the newly created object. If the aforementioned -init takes too long, I’m sure the program won’t “wait” before starting to use the new object, will it? If not...
I have the following structure in matlab superClass < handle subClassA < superClass subClassB < superClass say I have a vector A of subClassA and a vector B of subClassB.

I am parsing an XML file where one of the fields I want to be immutable, ID, has to be set after the object is created. Should I set it to null, and throw an exception in the setID() method if ID!=null ? Edit: I am parsing an XML file, and at the beginning, I create an object whose fields and objects are populated using information in X...
