  2. Dynamic dispatch - Wikipedia

    en.wikipedia.org/wiki/Dynamic_dispatch

    The default form of dispatch is static. To get dynamic dispatch the programmer must declare a method as virtual. C++ compilers typically implement dynamic dispatch with a data structure called a virtual function table (vtable) that defines the name-to-implementation mapping for a given class as a set of member function pointers. This is purely ...

  3. Virtual method table - Wikipedia

    en.wikipedia.org/wiki/Virtual_method_table

    Thus, fetching the method's address from a given offset into a virtual method table will get the method corresponding to the object's actual class. [2] The C++ standards do not mandate exactly how dynamic dispatch must be implemented, but compilers generally use minor variations on the same basic model.

  4. Late binding - Wikipedia

    en.wikipedia.org/wiki/Late_binding

    In computing, late binding or dynamic linkage [1] —though not an identical process to dynamically linking imported code libraries—is a computer programming mechanism in which the method being called upon an object, or the function being called with arguments, is looked up by name at runtime.

  5. Multiple dispatch - Wikipedia

    en.wikipedia.org/wiki/Multiple_dispatch

    This is a generalization of single-dispatch polymorphism where a function or method call is dynamically dispatched based on the derived type of the object on which the method has been called. Multiple dispatch routes the dynamic dispatch to the implementing function or method using the combined characteristics of one or more arguments.

  6. Polymorphism (computer science) - Wikipedia

    en.wikipedia.org/wiki/Polymorphism_(computer...

    Dynamic polymorphism is more flexible but slower—for example, dynamic polymorphism allows duck typing, and a dynamically linked library may operate on objects without knowing their full type. Static polymorphism typically occurs in ad hoc polymorphism and parametric polymorphism, whereas dynamic polymorphism is usual for subtype polymorphism.

  7. Dispatch table - Wikipedia

    en.wikipedia.org/wiki/Dispatch_table

    In computer science, a dispatch table is a table of pointers or memory addresses to functions or methods. [1] Use of such a table is a common technique when implementing late binding in object-oriented programming .

  8. Fragile base class - Wikipedia

    en.wikipedia.org/wiki/Fragile_base_class

    The fragile base class problem has been blamed on open recursion (dynamic dispatch of methods on this), with the suggestion that invoking methods on this default to closed recursion (static dispatch, early binding) rather than open recursion (dynamic dispatch, late binding), only using open recursion when it is specifically requested; external ...

  9. Call site - Wikipedia

    en.wikipedia.org/wiki/Call_site

    In programming, a call site of a function or subroutine is the location (line of code) where the function is called (or may be called, through dynamic dispatch). A call site is where zero or more arguments are passed to the function, and zero or more return values are received. [1] [2]
