How to Extract Private Class Members With Doxygen?

To extract private class members with Doxygen, you can use the EXTRACT_PRIVATE configuration option in the Doxygen configuration file. This option allows you to include private class members in the generated documentation. By setting this option to YES, Doxygen will generate documentation for private members as well as public and protected members.

In addition to enabling the EXTRACT_PRIVATE option, you can also use other configuration options such as EXTRACT_ALL and EXTRACT_STATIC to control which class members are included in the documentation. By customizing these options, you can ensure that all relevant class members, including private ones, are included in the generated documentation.

Once you have configured the EXTRACT_PRIVATE option and any other relevant options in the Doxygen configuration file, you can run Doxygen to generate the documentation for your project. The resulting documentation will now include information about private class members, making it more comprehensive and useful for developers who need to understand the internals of your code.

What is the correct way to document private member functions in doxygen?

Private member functions in doxygen should be documented using the same syntax as public member functions. This includes adding a brief description of the function's purpose, as well as any parameters, return values, and exceptions that the function may throw.

However, to indicate that a member function is private, you should use the \private command in the doxygen comment block. This will inform doxygen that the member function should not be included in the public documentation.

For example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

/**
 * \brief This is a private member function
 * \private
 * 
 * This private member function does something important.
 *
 * \param value some value to process
 * \return the result of the processing
 * \throw SomeException if an error occurs
 */
int privateFunction(int value);

By using the \private command, you can ensure that your private member functions are properly documented while still keeping them hidden from the public API documentation.

How to access private class fields in doxygen?

In Doxygen, you can access private class fields by setting the EXTRACT_PRIVATE option to YES in the Doxyfile configuration file. This will instruct Doxygen to generate documentation for private class members.

Here's how you can access private class fields in Doxygen:

1. Open the Doxyfile configuration file in a text editor.
2. Search for the EXTRACT_PRIVATE option and set it to YES.
3. Save the file and run Doxygen to generate the documentation.
4. In the generated documentation, you should now be able to see documentation for private class fields.

By setting the EXTRACT_PRIVATE option to YES, you can access private class fields in the documentation generated by Doxygen.

How to document private member functions in doxygen?

In Doxygen, you can document private member functions just like you would document any other member function. Here's how you can do it:

1. Place a comment block before the private member function definition that starts with "/**" or "/*!". This signals to Doxygen that you want to document the member function.
2. Inside the comment block, you can use Doxygen tags to provide information about the private member function. Some common tags to use include @brief (to provide a brief description of the function), @param (to describe the function's parameters), @return (to describe the function's return value), and @see (to provide references to related functions or classes).
3. Make sure to include a brief description of what the private member function does, any parameters it takes, and what it returns.

Here's an example of how you can document a private member function in a class:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

class MyClass {
public:
    MyClass(); // Constructor

    /**
     * @brief Set the value of the private member variable.
     * 
     * @param value The new value to set.
     */
    void setValue(int value);

private:
    /**
     * @brief Multiply the private member variable by a given factor.
     * 
     * @param factor The factor to multiply by.
     * @return The result of the multiplication.
     */
    int multiply(int factor);

};

By following these steps, you can effectively document private member functions in Doxygen. This documentation will help other developers understand how to use these functions and what they are intended to do.
