getter-setter

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 3 days ago . Improve this question I wondered whether it is possible in C++ to do the same stuff like in Java. That means something like this: public class A { private A a1; private A a2; A getA1(){ return a1; } A getA2(){ return a2; } void setA1(A a1){ this.a1 = a1; } void setA2(A a2){ this.a2 = a2; } } Now I

问题 I know that it is not pythonic to use getters and setters in python. Rather property decorators should be used. But I am wondering about the following scenario - I have a class initialized with a few instance attributes. Then later on I need to add other instance attributes to the class. If I don't use setters, then I have to write object.attribute = value everywhere outside the class. The class will not have the self.attribute code. Won't this become a problem when I need to track the

问题 I want to monkeypatch event listener registrations. I found this answer showing how to do it for addEventListener : const nativeEventListener = EventTarget.prototype.addEventListener; EventTarget.prototype.addEventListener = function(...args) { if (this.matches('div') && args[0] === 'click') { console.log('listener is being added to a div'); debugger; } nativeEventListener.apply(this, args); } // then, when an event listener is added, you'll be able to intercept the call and debug it:

问题 Lets say I have the following getter/setter methods get next() { console.log(this.people[this._index], this._index); return this.people[this._index]; } set next(i: any) { this._index = (+i) + 1; this._index = (+i) % this.people.length; } and I want to call this in the following way: <ng-template ngFor let-person="$implicit" [ngForOf]="people" let-i=index let-last=last> <app-card [cardItem]="people[i]" [nextCard]="next(i)"></app-card> </ng-template> PS: Think of this as circular array.

问题 Consider this class: class test { public function __set($n, $v) { echo "__set() called\n"; $this->other_set($n, $v, true); } public function other_set($name, $value) { echo "other_set() called\n"; $this->$name = $value; } public function t() { $this->t = true; } } I am overloading PHP's magic __set() method. Whenever I set a property in an object of the test class, it will call __set() , which in turn calls other_set() . $obj = new test; $test->prop = 10; /* prints the following */ __set()

问题 ECMAScript allows us to define getters or setters as following: [text/javascript] var object = { property: 7, get getable() { return this.property + 1; }, set setable(x) { this.property = x / 2; } }; I can work around if I'm using a class : [text/coffeescript] "use strict" Function::trigger = (prop, getter, setter) -> Object.defineProperty @::, get: getter set: setter class Class property: '' @trigger 'getable', -> 'x' member: 0 But what if I want to define trigger on the object directly -

问题 JAVA 8 I have a POJO class: class User { private String name; private String password; //... Getters / Setters ... } Which i will use as an entity class. In the getter/setter for password , I want to add decryption/encryption logic. public String getPassword() { return EncryptionFactory.decryption(password); } public void setPassword(String password) { this.password = EncryptionFactory.encryption(password); } EncryptionFactory is a utility class which encrypts/decrypt a String . My question

问题 I have many java beans in my project. I need to generate a JUnit Test class for them. The test methods generated using Eclipse 3.2 & junit 4.4 look like the following: public void testGetName() { // fail("Not yet implemented"); } @Test public void testSetName() { // fail("Not yet implemented"); } @Test public void testGetEmployeeid() { // fail("Not yet implemented"); } @Test public void testSetEmployeeid() { // fail("Not yet implemented"); } some of my beans have more than 100 fields...
