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:

    “Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune—what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.”
    —Susanne K. Langer (1895–1985)

    “In inner-party politics, these methods lead, as we shall yet see, to this: the party organization substitutes itself for the party, the central committee substitutes itself for the organization, and, finally, a “dictator” substitutes himself for the central committee.”
    —Leon Trotsky (1879–1940)
