setter

问题 Is there any way (utilizing Reflection I hope) that I can make an instantiated object immutable along with all of its public properties ? I have a class from someone else's codebase (no source available) that I need to utilize and I basically want an exception to be thrown if any piece of code anywhere tries to call a public setter within this class after it has been instantiated. Note: I do not want to create a wrapper object around the class in order to implement this. I am lazy. 回答1: No

问题 I have a class TileGrid that holds an std::vector< std::vector<Tile> > . Accessing the Tile objects in the vector works, but I can't change their properties? For the sake of completion, here are all the relevant classes: tilegrid.h #include <vector> #include "tile.h" class TileGrid { public: TileGrid(); TileGrid(unsigned int rows, unsigned int cols); virtual ~TileGrid(); unsigned int getRows() const { return rows_; }; unsigned int getCols() const { return cols_; }; Tile atIndex(unsigned int

问题 I've been searching around but I just can't seem to find what I'm looking for, so I'll give it a go here. Situation: I have the class MainWindow and MainWindowData. In MainWindowData are only public properties defined with the attribute UpdateGUI. public class UpdateGUI : Attribute { } public class MainWindowData { [UpdateGUI] public string TESTVAR { get; set; } } Now I want to add a method to each property's setter method in MainWindowData. More specific: void OnPropertyChanged(String

问题 I have a nested child class with public properties with private setters. In the parent class I am able to use Automapper to map to the child class and the values of the private setters are being set. Everything I've read points to Automapper not supporting this and requiring a custom constructor in the child class to populate private setters. Is the current version using reflection or something to map the private setters? The setters are definitely private because in the parent class I am

问题 I'm trying to understand getters and setters on JS and I can't seem to get pass this error. Can anyone provide any insight as to why I'm getting this error? var book = { year: 2004, edition:1, get newYear(){ return "Hello, it's " + this.year; }, set newYear(y, e){ this.year = y; this.edition = e; } }; Uncaught SyntaxError: Setter must have exactly one formal parameter 回答1: The setter function is called when you assign the value that setter represent: var obj = { set a(newVal) { console.log(

问题 Assuming we have a class InnerClass with attributes and getter/setter. We also have a class OuterClass containing the InnerClass. e.g. class InnerClass { private int m_a; private int m_b; public int M_A { get { return m_a; } set { m_a = value; } } } class OuterClass { private InnerClass innerClass } How would I implement a correct getter and setter for the innerClass member of OuterClass? Thanks in advance! 回答1: The syntax wouldn't be any different. Just... public InnerClass InnerClass { get
