In the process of program development, we often write such classes: some or all of the properties of a class do not want to be accessed directly by the outside world, without the public field being decorated. In this way, the method invocation becomes the only way to access these properties. JavaBean is a good example of strict adherence to object-oriented design logic and all properties are private. For any attribute xxx, there is a public getxxx () method to get the property and the public's S

This article mainly introduces related information about the setter and getter methods in JavaScript, which is very good and has reference value, for more information, see the setter and getter methods in javascript. They are not standard methods, it is only supported in non-ie browsers (maybe there are other ways to do it in ie kernel? But it can be used to do many things, such:

Content Highlights:I. Object propertiesObject properties are composed of a name, a value, and a set of attributes. In ES5, a property value can be substituted by one or two methods, both getter and setter. Properties defined by getter and setter are called "Memory Properties", which are different from "data Properties" and data properties are a simple value.When the program queries the value of accessor pro
The overall declaration and implementation of setter and getter methods can be replaced with @property later, but in the later iOS development, the setter method or Getter method is used alone in a relatively high frequency, the application is more extensive!@Interface Person:nsobject{NSString *_name;int _age;Sex _sex; Enum Type here, which is a basic data type without adding "*"float _height;}@endThe sette
Original sticker: Why Python does not need getter and setterGetter and setter are widely used in Java. A good Java programming guideline is to set all properties to private, and write getter and setter functions for the properties for external use. The benefit of this is that the specific implementation of the attribute is hidden, and when changes are needed in the future, only the
JavaScript in the setter, getter is the usual method of less contact, which itself is not a standard method, only in non-IE browser support (ie kernel may have other ways to do it?) For the time being, but there are many things you can do with it, such as:
1. Access Restrictions on data:
A.value is a getter method call to a value variable that prevents access to the value variable if an exception is throw

Private variables
Why do we use private instance variables?
Because we don't want other classes to be directly dependent on these variables. And in the whim, we can also flexibly modify the variable type and implementation.
However, why are programmers automatically adding getter and setter methods to objects to expose private variables as if the variables were public.

A property is one embodiment of encapsulation in an object-oriented language, and setting a property in a custom class is equivalent to defining a private variable, a setter method, and an accessor (getter method), where the definition of the variable is The Declaration and implementation of the method is automatically generated by the system and is managed and optimized accordingly, without the need for developers to worry about it.Declaration of the

Suppose there is a myclass class, which defines a member text. Its reading and writing are as follows:
//MyClass.h file@interface MyClass: NSObject {NSString *text;}-(void) init;-(void) logText;@end//MyClass.m file@implementation MyClass - (void)init {text = @"some text";}- (void)logText {NSLog(@"%@", text);}@end
The above program uses constants to initialize text, so there is no need to w
