Can a class return an object of itself. In my example I have a class called "Change" which represents a change to the system, and I am wondering if it is in anyway against design principles to return an object of type Change or an ArrayList which is populated with all the recent Change objects. ...
Consider a production planning application with many products. Each product has a list of InventoryControl objects keyed on InventoryControlType. Depending on the algorithm we run for production planning, we need to access to different types of InventoryControl objects for a given product. This works OK. However, today I needed to introd...

What I think I need to do is to create a class that has a string for the data field and a length specifying the length of the string. And then somehow restrict it so that the string n...
I'm looking for inspiration on how to design classes from scratch in a project with multiple developers in different locations (so no whiteboard sessions.) Let's say you're tasked with implementing a rather big feature that is going to be used by the other developers later in the project. This feature will require several classes and wi...
DatePeriod is a PHP class for handling recurring dates. It has a very limited number of methods. So when I want to do basic array functions with the recurring dates, I have to copy it to an array with iterator_to_array. Strangely, copying it seems to clobber it. Any ideas why? $p=new DatePeriod(date_create('2008-01-01'), ...

Lets use a standard OOP example... say every time a user enters a name for a pet in a text field and clicks a button a new pet object is created via the petFactory function. function pet(name) { this.nam...
What would be the best way to structure orders for a restaurant (available languages are php and javascript)? Since there are multiple tables (the ones you keep things on...), I thought of using objects in javascript. But I am quite new to javascript and absolutely new to OOP, so I'm not sure whether this is the best solution, and whethe...
I'd like to write a small JavaScript (framework) that can chain functions with all following functions being aware of the data of its predecessor. Basically, I'm not interested in the bloat (I realize it's small, for my even smaller project though it's bloat) that jQuery provides but would like to mimic some of its behavior -- primarily...

If for example, i have a class Car with properties Colour, Model, Make, Year and a method Save, which will either insert or update the record.

I am importing legacy C++ code using Rhapsody. One class has many (several dozen) attributes I'd rather see imported as separate classes. I've tried different "options" settings with no results. Is there a way to do this, other than redo all by hand? ...

Most of you should know that 'famous' article about "Writing Robust PHP Backends with Zend Framework" After an insteresting reading, i decided to give it a try, since i couldn't be able to find the gold solution to handle my datas. Then, i tried to write kind of a skeleton, to have a concrete example. But some points looks weird for m...
Over the past few years I've been on projects where we've run into a similar problem in our object hierarchy that always seems to cause problems. I was curious if anyone here knew of a classical OOP (Java, C#, PHP5, etc) design pattern that could gracefully handle this situation. Say we have an existing system. This system has, among ...
