overriding

问题 guys. I need to override 2 functions in different classes (CatalogSearch/Layer.php and CatalogSearch/Mysql4/Fulltext/Collection.php). So, I have a config file: <config> <modules> <my_modulename> <version>0.1</version> </my_modulename> </modules> <global> <models> <catalogsearch> <rewrite> <layer>My_Modulename_Model_CatalogSearch_Layer</layer> <mysql4_fulltext_collection>My_Modulename_Model_CatalogSearch_Mysql4_Fulltext_Collection </mysql4_fulltext_collection> </rewrite> </catalogsearch> <

问题 I'm trying to override the Resetting Controller of the FOSUserBundle. My own UserBundle is overriding the whole bundle, and it's working fine for e.g. templates but it's the first time I try to override a Controller and it seems like I'm doing something wrong. Trying it that way (only copying in the first line since the rest of the controller is still the default one): namespace UserBundle\Controller\User; use FOS\UserBundle\Controller\ResettingController as BaseController; ... class

问题 Due to the answers I have received I am now doing this a different way. Is there any way to override setPreferredSize() and getPreferredSize() so it will actually set the size of the component to a number higher than was actually input, and get a number that is a number lower than it actually is? Here I am overriding both methods to set the size of a panel to 100 pixels more than what I actually put in setPreferredSize() and if I were to get the preferred size, I would like it to return what

问题 I´ve found numerous tutorials on how to do this on D6, BUT, it seems that the example code I´ve found doesn´t quite work on Omega subtheme. Here´s the code I´ve found it suits me best (via Trellon): Inside template.tpl.php: <?php function themename_theme($existing, $type, $theme, $path) { return array( ... // tell Drupal what template to use for the user register form 'user_register' => array( 'arguments' => array('form' => NULL), 'template' => 'user-register', // this is the name of the

问题 I have a class: class ProjectService : public CProjectT<CSoapMSXMLInetClient> { ... } I have implemented HRESULT ConnectToServer(); function in this derived class. Then I instantiated an object and called a function: ProjectService project; project.f1(); now, f1() calls f2() and f2() calls ConnectToServer() . All of those functions are members of CProjectT<CSoapMSXMLInetClient> The problem here is, CProjectT<CSoapMSXMLInetClient>::ConnectToServer() is called instead of ProjectService:

问题 I've made an Animal superclass, Shark and Whale subclasses. What would I use to print out just the Shark objects from this arraylist? Driver: import java.util.ArrayList; public class Creator { public static void main(String[] args){ ArrayList<Animal> obj = new ArrayList<Animal>(); obj.add(new Shark("James")); obj.add(new Shark("Mike")); obj.add(new Whale("Steve")); obj.add(new Whale("Tommy")); for (Animal a: obj){ System.out.println(a.getName()); } } } 回答1: You can use the instanceof to check

问题 I imported an Android project and it has a lot of @override method annotations, which Eclipse is complaining about (although the project has worked before and it should not be complaining). I'm using java sdk 1.7. Does anyone know anything about this? Thanks. 回答1: Are the overrides on interface methods or superclass methods? Interface methods can only be marked with this annotation as of Java 6. What is the compiler compliance level set to for your project? What about for Eclipse in general?

问题 I would like all my objects to have an ID and I wish to serialise it for some child class but not for some others for example: public class A { protected Long id; ..getter and setter } public class B extends A { @Override @JsonIgnore public Long getId() {..} @Override @JsonIgnore public void setId(Long id) {..} } public class C extends B { @Override @JsonInclude public Long getId() {..} @Override @JsonInclude public void setId(Long id) {..} } public class Test { Set<C> tests ... ..getter

问题 I'm trying to override class Mage_Catalog_Block_Navigation located at app/code/core/Mage/Catalog/Block/Navigation.php I've created this three files: 1.- app/code/local/Global/Catalog/Block/Navigation.php 2.- app/code/local/Global/Catalog/etc/config.xml 3.- app/etc/modules/Global_All.xml Code: Global_All.xml <?xml version="1.0"?> <config> <modules> <Global_Catalog> <active>true</active> <codePool>local</codePool> </Global_Catalog> </modules> </config> Config.xml <?xml version="1.0"?> <config>

问题 I discovered a method of extending the core jQuery init function (which is what gets called anytime you use the $() or jQuery() function). This is not possible using the ordinary proxy pattern but the following code makes it work: var origInit = jQuery.fn.init; jQuery.fn.init = function(selector, context, rootjQuery) { if (some condition) { //custom code here, possibly returning some other jQuery object than //what jQuery would normally return } return origInit.call(jQuery.fn, selector,
