Method (computer Science) - Virtual Methods

Virtual methods are the means by which a class object can achieve polymorphic behavior. Non-virtual methods, or regular methods, are those which do not participate in polymorphism.

C++ Example:

#include #include class Super { public: virtual void iAm { std::cout << "I'm the super class!\n"; } } class Sub : public Super { public: void iAm { std::cout << "I'm the subclass!\n"; } } int main { std::unique_ptr inst1(new Super); std::unique_ptr inst2(new Sub); inst1->iAm; // calls Super::iAm inst2->iAm; // calls Sub::iAm }

Famous quotes containing the words virtual and/or methods:

    “Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.”
    —Jean Baudrillard (b. 1929)

    “The comparison between Coleridge and Johnson is obvious in so far as each held sway chiefly by the power of his tongue. The difference between their methods is so marked that it is tempting, but also unnecessary, to judge one to be inferior to the other. Johnson was robust, combative, and concrete; Coleridge was the opposite. The contrast was perhaps in his mind when he said of Johnson: “his bow-wow manner must have had a good deal to do with the effect produced.””
    —Virginia Woolf (1882–1941)
