overriding

问题 I'm running the following version of PHP: PHP 5.3.15 with Suhosin-Patch (cli) (built: Aug 28 2012 18:19:13). I have a class which inherits from \MongoGridFS: class PdfGrid extends \MongoGridFS { // ... public function update( array $criteria , array $new_object, array $options = array()){ $options['safe'] = true; if ( isset($criteria['_id']) && ! $criteria['_id'] instanceof \MongoId){ $criteria['_id'] = new \MongoId($criteria['_id']); } return parent::update($criteria, $new_object, $options);

问题 So I am trying to override the core CustomerController massDelete action. This is what I have so far: config.xml <frontend> <routers> <customer_massdelete> <args> <modules> <MyModule_MyExtension before="Mage_Adminhtml">MyModule_MyExtension</MyModule_MyExtension> </modules> </args> </customer_massdelete> </routers> </frontend> My Controller: app/code/local/MyModule/MyExtension/controllers/CustomerController.php <?php require_once 'Mage/Adminhtml/controllers/CustomerController.php'; class

问题 In my Joomla template I would like to override some styles, so I've created my own css and added styles, also media queries. Most of all works only if I use the !important keyword and something does not work at all. For example: <div id="content_right" class="span3"> In this div I have class and id. I cannot modify the class, because it affects other divs into the template, so I would like to add some style by id. I've added it but it does not work. I've inspected with Firebug and css is

问题 I am trying to add a piece of code at the begining of every page in a Drupal site. Since I have more than one page template, I want to do this programatically... but am not succeeding. I am still new and, though I get the gist of hooks, theme functions, and the such, I just can't figure the correct way to achieve this. So far I've overriden the theme_preprocess_page(&$vars) to add the necessary css and js: function mytheme_preprocess_page(&$vars) { if(condition) { drupal_add_js(drupal_get

问题 I try to override this method def sum[B >: A](implicit num: Numeric[B]): B = ... in a subclass where type A is already fixed to Int . I already tried override def sum: Int = ... but this doesn't override of course, leading to different method resolution based on the dynamic type at runtime. Going further, def sum[B >: Int](implicit num: Numeric[B]): Int does override, while def sum[B >: Int](implicit num: Numeric[Int]): Int does not, as well as def sum(implicit num: Numeric[Int]): Int Why is

问题 so I'm not well versed in overriding hashCode and I seem to have some infinite recursion somehow going on with the hashCode method. Here is my scenario, I have a class DuplicateCache that is a cache object that checks for duplicate objects in our system. I have a static inner class Duplicate which represents the Duplicate objects. The DuplicateCache maintains a HashMap to keep track of all its entries. Each entry consists of a Duplicate object as the key and a Long object as the value. I am

问题 Actual question Is it possible to override the blocking of a package's (re-)installation after it has been required/loaded? I understand that blocking a "true" re-installation to the same library that the package was loaded from makes perfect sense once the package is in use. But my use case is a bit different Background I like the idea of having a "sandbox library" to test own packages. Besides the package(s) to test, those sandbox libraries contain all base packages of a clean base R

问题 Let's say I have the following base class: class Base { public: virtual void f() {}; }; If I want to write a class that will override the f() and will not allow to override it to it's derived classes can write it using following approaches: Approach 1: class Derived : public Base { public: virtual void f() override final {}; }; Approach 2: class Derived : public Base { public: void f() final {}; }; Approach 1 is a fully detailed when Approach 2 more compact and final still says that f() is

问题 I have the following class called A , with the method getValue() : public class A { public final int getValue() { return 3; } } The method getValue() always returns 3 , then i have another class called B , i need to implement something to access to the method getValue() in the class A , but i need to return 4 instead 3 .
