getter-setter

问题 is a way how i can create a getter, but hide it or add it in proto ? example here, i use simple OBJ. Look get sprite() buttonsData[name] = { name:name, type:bType, slot:slot, get sprite() { return this.slot.currentSprite }, }; but I find it very polluting, how can I hide it or write it so that it does not disturb my eyes in a debug terminal? i want hide get sprite() { return this.slot.currentSprite } 回答1: You can embed an anonymous prototype using Object.create(), though do note that this

问题 I have a variable called List<String> names; if i have a method like Iterator getNames() { return names.iterator(); } Is it technically still a getter method because i changed it to Iterator? 回答1: Even though the JDK allows this, its not a good idea to do it. For one, there are conventions based off of the naming of your methods, that have some dependencies on them. JavaBean objects use getters and setters to set bean properties. If they disobey the convention, the program will fail. See

问题 Just a theoretical question that could lead to some considerations in terms of design. What if you were to replace POJOs with this reusable class ? It might avoid some boilerplate code but what issues could it bring about ? // Does not include failsafes, guards, defensive copying, whatever... class MySingleGetterAndSetterClass{ private HashMap<String,Object> myProperties; public SingleGetterAndSetter( String name ){ myProperties = new HashMap<String,Object>(); myProperties.put( "name", name )

问题 For instance in main method I have setFirstName() and call the Contact class to do this. In the contact class I know I should use: public String getName() and then public void setFirstName(String name) I know this is the right way to do that. But instead, I find that if i do: public String setFirstName(String name) { return this.name=name; } this will also work and I don't need to use getName() method. Can anyone please help me out why is that? Is my accessor/mutator method correct? 回答1: It

问题 So, I've got a class (IKImageView) with a bunch of properties. I know that view setProp: BOOL returns void. However: BOOL b = view.prop = NO; seems to work. If I had a function f() that returns a boolean, does anyone know if this is really doing: [view setProp:f()]; Bool b = [view getProp]; or [view setProp: f()]; Bool b = f(); or BOOL TMP = f(); [view setProp: TMP]; BOOL b = TMP; I ask because when I do: BOOL b = view.hasHorizontalScroller = YES; NSLog(@"b is %d scroll is %d", b, [view

问题 By default NetBeans generates 3 line getters and setters like so: public int getFoo() { return foo; } Is there a way to make it generate it in one line like so: public int getFoo() {return foo;} I did not find any get or set templates in Tools -> Options -> Editor -> Code Templates Is there some other way to edit them or maybe a plugin? 回答1: As seem you can't really, but I've found a patch in this blog post which modifies Netbeans source. 回答2: on NB 7.2+ you can create your own generator:

问题 I have a python property like this: class Foo: @property def maxInputs(self): return self._persistentMaxInputs.value @maxInputs.setter def maxInputs(self, value): self._persistentMaxInputs.value = value Currently, the value of maxInputs can be get and set by everyone. However, I want to allow everyone to get the value of the maxInputs , but it should only be set inside of the Foo class. So is there a way to declare a property with a private setter and a public getter? 回答1: Python has no

问题 Context: I have a company model with many projects , having many tasks . The company also has many employees , which in turn have many tasks . Schema: Problem: I'm building a form to create a project where the user can add multiple tasks . Upon submission the form should create a single project record, one or more task records with hours and employee_id attributes and (!) check if the employee name already exists in the database or create a new one. I've approached this by adding jquery

问题 I create a class whose objects are initialized with a bunch of XML code. The class has the ability to extract various parameters out of that XML and to cache them inside the object state variables. The potential amount of these parameters is large and most probably, the user will not need most of them. That is why I have decided to perform a "lazy" initialization. In the following test case such a parameter is title . When the user tries to access it for the first time, the getter function

问题 I have seen this kind of code in c#: private int id {get;set;} but I would only create getter for the field cause if there is get and set for it is the same as public field is the only way is : public int getId(){return id;} How to automaticly generate only getters in VS2010 回答1: What you have implemented is known as an Automatic Property they look like this: private string Name { get; set; } Automatic properties merely syntactical sugar and in reality, provide a succinct, quick way to
