There are three main types of access specifiers in C++ (or access modifiers), which control the visibility and accessibility of class members. These access specifiers are pivotal in defining how different parts of a class can be accessed and utilized within a program. In this section, we will...
However, it is also important to make some member functions and member data accessible so that the hidden data can be manipulated indirectly. The access modifiers of C++ allows us to determine which class members are accessible to other classes and functions, and which are not. For example, cl...

SWIG will generate Java access modifiers that are a one-to-one mapping of the C++ access specifiers. So if a method is public in C++ it will also be public in Java, and similarly protected in C++ becomes protected in Java. This is fine for all of the methods in the above example, ex...
Members defined after theprivatespecifier are accessible to member functions only and can’t be referred directly from the code that uses the class. A class is usually constructed with two sides in mind - the designer of the class and the user of the class. The latter is usually the one ...

在C++ 中使用 public 函数来检索类的私有成员 本文将解释几种如何使用 C++ 访问类的私有成员的方法。 在C++ 中使用 private 访问指定器来封装类成员 访问说明符用于实现面向对象编程的核心特征-称为封装。结果,我们限制了对类的特定数据成员的直接访问,并从本质上构造了一个对类数据进行操作的接口。C++ 提供了几...
数据封装是面向对象编程的一个重要特点,它防止函数直接访问类类型的内部成员。类成员的访问限制是通过在类主体内部对各个区域标记public、private、protected来指定的。关键字public、private、protected称为访问修饰符。 一个类可以有多个 public、protected 或 private 标记区域。每个标记区域在下一个标记区域开始之前或者在...
