overriding

问题 I am trying to override Woocommerce's templates files by duplicating them in my custom theme directory / woocommerce / templates, but the changes don't appear (I tried simply adding classes to begin with) on the website. Is there something I am doing wrong ? Thank you for your concern. 回答1: While the directory structure in the WooCommerce plugin itself is: /plugins/woocommerce/templates/ You should define it like the following in your theme (note the missing templates dir): /yourtheme

问题 I am trying to Iterate directories in Perl, getting introspectable objects as result, mostly so I can print fields like mtime when I'm using Dumper on the returns from IO::All . I have discovered, that it can be done, if in the module IO::All::File (for me, /usr/local/share/perl/5.10.1/IO/All/File.pm ), I add the line field mtimef => undef; , and then modify its sub file so it runs $self->mtimef($self->mtime); (note, this field cannot have the same name ( mtime ) as the corresponding method

问题 I know that private methods are hidden in Derived class and they cant be overridden but my question is different.. Please go through the following problem. My question is mentioned in the problem stated below: TestPolymorphism.java class CheckParent { private void display() { System.out.println("This is parent class"); } } class CheckChild extends CheckParent { void display() { System.out.println("This is child class"); } } public class TestPolymorphism { public static void main(String[] args

问题 I'm currently working on a port of an existing library which makes use of ostream to write to a terminal. The ostream was derived as part of the port. The ostream derivative class used is defined as so: class owstream: public std::ostream { public: CTerminal * output; giac::context * contextptr; owstream(CTerminal *, giac::context * contextptr , int = 0); virtual ~owstream(); }; This is used to output some data, typically integers and doubles. The problem is that the platform I'm working on

问题 I'm working on code that takes two arrays with strings (the strings are just sentences) and allocates them to classes which are held in another array (The Sentence class array shown below in the code). So here's my problem. When popList() is called, the for loop runs through twice and works fine, putting the first index of addStrings and addTranslation into the first class in the array. However, when the loop indexes up and runs temp.sentence = addStrings[1] again, it OVERRIDES the first

问题 I'm trying to understand how polymorphism, object slicing and pointers work in this block of code. I'm working in Visual Studio. #include <iostream> class Man { public: virtual void speak() { std::cout << "I'm a man." << "\n"; } private: }; class Soldier : public Man { public: virtual void speak() { std::cout << "I'm a soldier." << "\n"; } private: }; int main() { Man man1; Soldier soldier1; man1 = soldier1; std::cout << "Man1: "; man1.speak(); Man *man2 = new Man; Man *soldier2 = new Soldier

问题 This question already has answers here : Using GetHashCode to test equality in Equals override (8 answers) Closed 6 years ago . given the person class: class person { public string name; public int age; } say, i override the class person`s GetHashCode method: public override int GetHashCode() { unchecked { hashCode = 17; // ...some code here... } return hashCode; } and based on msdn`s instruction, i also need to override the Equality, so i did this: public override bool Equals(object obj) { /

问题 I have Hashmap,how to override equals method for the hashmap? Thanks. 回答1: if you want you can do: HashMap<String, String> map = new HashMap<String, String>(){ @Override public boolean equals(Object o) { // TODO comparison here return super.equals(o); } }; map.equals(new HashMap<String, String>()); 回答2: In HashMap already equals() method is overrriden.If you want to override object class equals() method eclipse shortcut key--->alt+shift+s+v Select the equals method click on ok. 回答3: You will
