setter

问题 I'll try to keep it short. I have classes with many instance variables (30+) and hence many getters/setters. The classes by themselves are simple, but because of the getters/setters the LOC just exploded (and there also was way too much code duplicity). So I removed the attributes and stored them in a map, like this public class MyTechnicalToolClassX { //...constructor private Map<String, Object> data; public Object getAttributeByKey(AttributeKey key) { // ...doStuff, check data associated

问题 How does one get a reference the the getter and setter functions in actionscript 3? if a method is defined on the calls, e.g. public function blah():String { ...} I can get a reference to it by just saying blah or this.blah How do get a reference to public function get blah2():String {} public function set blah2(b:String):void {} Thanks! 回答1: Original response: Unfortunately, you will not be able to store references to those as functions. The getter and setter methods are actually built

问题 I'm trying to make a manual setter/getter method in C#, but i'm getting the following error from the "set"-line: Error: The best overloaded method match for 'System.Collections.Generic.ListPackage.Add(Package)' has some invalid arguments private List<Package> packages = new List<Package>(); public List<Package> Packages { set { packages.Add(value); } get { return packages; } } 回答1: Your code should look like this. private var packages = new List<Package>(); public List<Package> Packages { set

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago . So I know there are a lot of questions on getters and setters in general, but I couldn't find something exactly like my question. I was wondering if people change the use of get/set depending on different languages. I started learning with C++ and was taught to use getters and setters. This is what I understand:

问题 I am converting a project in to Swift code and have come across an issue in a setter. My Objective-C code looked like this: - (void)setDocument:(MyDocument *)document { if (![_document isEqual:document]) { _document = document; [self useDocument]; } } and allowed my View Controller to run this each time the document was set (typically in the prepareForSegue: method of the presenting View Controller). I have found the property observers willSet and didSet but they only work when the property

问题 How do I emulate PHP-style __get() and __set() magic getter/setters in JavaScript? A lot of people say that this is currently impossible. I am almost certain that it is possible because projects like nowjs (http://nowjs.com) do something like this. I know that you can utilize get and set, but these don't work when you're not sure what the property name will be. For example, what if you wanted an event handler to execute when a new property is created ? Example of what I'd want to do: var obj

问题 I would like to call a Setter (WPF specific) passed in a code behind. void Invoke(Setter setter) { //I am interested what to do here, ? } the setter will be something like <Setter TargetName="SomeUiElement" Property="SomeProperty" Value="{Binding SomeValue}" /> //resolution similar to void Call(Setter setter) { setter.Property.SetValue(setter.TargetObject, setter.Value.GetValue()) } Thanks in advance. Please be specific. 回答1: Setters are not quite what they seem. When WPF activates them, they

问题 I want to intercept all assignments to a field which is annotated with MyAnnotation in this case. If it works when the value is assigned with reflction is much better. This is what I tried, but it does not run, and I think that something else might be wrong: public privileged aspect MyAnnotationAspect { pointcut hasAnnotation(MyAnnotation annotation) : @annotation(annotation); pointcut methodExecution() : execution(* *(..)); Object around(MyAnnotation annotation) : set(String word) &&

问题 If I have a class: class A { public: A(); ~A(); int something(); } class B { public: B() {a = new A();}; ~B(); private: A *a; } main() { B x; } Is the only way to use object "a" in main is to have a getter for it? class B { public: A getA() {return *a;}; private: A *a; } And then if I wanted to set the private variable object, I would need a setter, and set it in main? Edit: I updated class A, B, main a little. Main question is, what is the best way if I create an object of B in main. Can I

问题 I'd like to create an upload form for documents. It's possible to select several so called 'agencies' and each of these agencies belongs to one specific market. What I want to do is, set the markets automatically. So in my controller I had something like this: $document->setMarket($document->getAgencies()->getMarket()); But since the agencies are an ArrayCollection, I can't call a getter on them. So I was thinking about a for each loop in order to get the markets for every single agency.
