overriding

Let's suppose we have a base class which has a virtual method: class BaseClass { virtual void MethodToOverride() const { DoSomething(); } }; And a derived class which overrides the method (depending on the situation we can make it again virtual or not): class DerivedClass : public BaseClass { void MethodToOverride() const { DoSomethingElse(); } } If we make a mistake, for example defining the MethodToOverride non const or with a wrong character, we simply define a new method, for example: void MethodToOverride() {} // I forgot the const void MthodToOverride() const {} // I made a typo So this

I have made some changes to Mage_Core_Controller_Request_Http but in the file distributed by with magento. This is not the best way, i know, but i have not been able to work out how to override a file in the Controller directory. I can find out how to override files in the controllers directory. Can anyone tell me how i can override Mage_Core_Controller_Request_Http in my own extension. thanks If you don't want to revert to the include path hack, you can also use reflection to set your own request class on the Mage_Core_Model_App model. You can use an observer for controller_front_init_before

I am struggling to understand Variables Shadowed Methods Overriden Concept of inheritance with Java. Case 1: class Car{ public int gearRatio = 8; public String accelerate() { return "Accelerate : Car"; } } class SportsCar extends Car{ public int gearRatio = 9; public String accelerate() { return "Accelerate : SportsCar"; } public static void main(String[] args){ Car c = new SportsCar(); System.out.println( c.gearRatio+" "+c.accelerate() ); } } Output: 8 Accelerate : Sportscar. Case 2: public class TestClass{ public static void main(String args[ ] ){ A o1 = new C( ); B o2 = (B) o1; System.out

Like this question , my admin overrides aren't working in my production environment but they are in my development environment (same django version). I've tried reordering the INSTALLED_APPS tuple in settings.py with no change (was the answer to the question linked above). Here's how I have my project constructed: /WebDJ/ # project dir +devices # unrelated app, but it uses templates (see below) +sales __init__.py admin.py models.py # has Customer and Transaction model classes +templates +admin +sales +Customer change_form.html +Transaction change_form.html +devices # lots of templates under

newbie question here: So in my university homework I have to override the object class equals method for a new class created by me. The new class is "Product", each product has an "id" attribute which is unique. So this is how I Overrided it: @Override public boolean equals(Object obj) { final Product other = (Product) obj; if (id != other.id) return false; return true; } The thing is that doing this is 1,5 points out of 10 and it made me suspicius to be that easy. So i started searching and I found things like: @Override public boolean equals(Object obj) { if (this == obj) return true; if

I have overrode the price rule of Magento product by overriding the getPrice() method in " Mage_Catalog_Model_Product_Type_Price " class, simple products are working fine and show the updated price which I mentioned in getPrice() i.e public function getPrice($product) { return 80; } But in the case of downloadable products it shows the original price, Any one here can tell me how can I override price in downloadable products. Thanks I would guess that this will be chased down to the getFinalPrice method of Mage_Downloadable_Model_Product_Price. Trying editing the file to return an obscure
