Hi Thanks for your valuable time. I want to learn c++ design patterns. I searched on web but I was not getting documents which gives me better details about design patterns. I was getting good details but those were in different URL's, I required all the information in one place only so that it will be better to know what all things a...
Hi there Do you know any book, blog, tutorial which explains in a detailed way the use of some open source projects? Maybe you have written such a tutorial, example of open source libraries and your final product is great for a beginner to understand it. I'm in the learning stage of OOP and I really need to learn by examples. I'll like...
I have heard this time and again, and I am trying to understand and validate the idea that FP and OO are orthogonal. First of all, what does it mean for 2 concepts to be orthogonal? FP encourages immutability and purity as much as possible, while OO seems built for state and mutation – a slightly organized version of imperative program...
I can declare a delegate as General type, like a public or internal types, also i can create it within a (abstract) class and make it protected, so just some classes can access to that delegate for example: delegate void PublicSample(); interface IMyInterface { event PublicSample mySample; } class Implementor : IMyInterface { ...

Hi, I don't think I am being silly here. class Parent { function load($function) { if (method_exists(__CLASS__, $function)) { // Load Function } } } Class Child extends Parent { function foo() { } } $this->Child->load('foo'); The problem is that __CLASS__ is returning 'Parent'. How do I get it to return Child?...
I have a web application (in ASP.NET MVC) with a Quotations controller. This controller can handle multiple Quotation types, MotorQuotation, PropertyQuotation, etc... Currently it is using inheritance i.e. a Quotation model and it's children, to model the domain. The various children classes have differences in the data they store and n...
I'm at the point in my first real application where I am adding in the user settings. I'm using Java and being very OO (and trying to keep it that way) so here are my ideas: Load everything in the main() and pass it all 'down the line' to the required objects (array) Same as above, but just pass the object that contains the data down t...
I am getting a hang of OOP and finally started creating them in my scripts. One thing I don't get it is the "$this" after creating an instance of class. For example, this guy coded: class Form { protected $inputs = array(); public function addInput($type, $name) { $this->inputs[] = array("type" => $type, "name" => ...
Hi all, I am supposed to write a simple Cinema Booking System, which allows a customer to make reservations for movies. The Cinema consists or different theatres, with different amount of seats, price and movie showtimes. The user should be able to input his name and other credentials and then make reservations for 1 or more movies a...
I am relatively new to javascript and I have watched two tutorial videos by Douglas Crockford on the subject. He recommends creating object oriented design in javascript in the following way, through the use of nameless functions and closures: function Class() { var privateVar1, privateVar2; function privateMethod1() { } functi...
I have a enterprise webapp that is extremely ajax heavy, all data goes though some sort of ajax, so is saving, updating deleting etc. Modeled after the MVC paradigm The site is mostly compromised of three parts Interface page An interface page only contains the interface and all the js that goes with it, no data processing of any kind....

How to solve this PLEASE? // class myClass = function (){ // member object this._localVars = { _elementClass:'.elem-class', _dots:null, _dotStatus:null }; // membe...
Hello! I have question connected with interfaces and abstract classes. I'll give to you simple example, that could explain what I want to do. So, Lets start. public interface A { string param1 { set; get;} string param1 { set; get;} A CreateObject(string p1,string p2); } public class MyClass1 : A { public string param1 { set; get;...
Of the object-oriented languages I know, pretty much all but C++ and Objective-C compile to bytecode running on some sort of virtual machine. Why have so many different languages settled on compiling to bytecode, as opposed to machine code? Is it possible in princible to have a high-level memory-managed OOP language that compiled to mach...
From everyone who've designed a modular enterprise application, I am interested in knowing how do you perceive modularization and what exactly are you parameters? Is layer-based modularization (like controller/web module, service module, domain module) a better approach? Or feature-based modularization better? And Why? In case of fe...
I am not sure what I am doing wrong, I have try and looked everywhere but nothing I do is working I am using the following code. - I know it is a little long, but if you have time could you please have a look. The issue part is <?php for ($a=0; $a<count($subresults); $a++) { echo '<li id="subcategory"><a id="nav" href="#/'.str_repl...
Hello! I have a class that takes many arguments to create. It’s a sort of an audio processor that needs a sample rate, sample resolution, number of channels etc. Most of the parameters have sane defaults. And most of them should be only settable in the initializer (constructor), because it makes no sense to change them afterwards. I do n...
All, I'm developing an application using Zend Framework to manage tenders for construction work. The tender will be a rather complex set of models with an architecture resembling the code snippet below. My question is... should I store the total value of the tender as part of the tender model, or should I compute it each time it is re...
In Java generics you can use "&" to specify multiple interfaces as type bounds for a type parameter. This allows us for example to manipulate objects of different types with common interfaces to be manipulated uniformly even if there is not an parent interface for those common ones. My question is, how can this be used? For What purposes...
