oop - 强制派生类调用 MATLAB 中的基函数？

Question

基类有一个函数f。派生类覆盖函数 f。我想为派生类的对象调用基类 f。我该怎么做？

这是代码示例。

    classdef base

        methods ( Access = public )
            function this = f( this )
                disp( 'at base::f' );
            end

        end
    end

    classdef derived < base

        methods ( Access = public )
            function this = f( this )
                % HERE I WANT TO CALL base::f
                this@base.f(); % this is an error

                disp( 'at derived::f' );
            end

        end
    end

d = derived();
d.f();
% here the result should be
% at base::f
% at derived::f

Answer 1

代替

this@base.f();

是

f@base(this)
