The name dynamic binding is sometimes used, [2] but is more commonly used to refer to dynamic scope. With early binding, or static binding, in an object-oriented language, the compilation phase fixes all types of variables and expressions. This is usually stored in the compiled program as an offset in a virtual method table ("v-table"). [3]
Dynamic binding (or late binding or virtual binding) is name binding performed as the program is running. [2] An example of a static binding is a direct C function call: the function referenced by the identifier cannot change at runtime. An example of dynamic binding is dynamic dispatch, as in a C++ virtual method call.
Delegation is dependent upon dynamic binding, as it requires that a given method call can invoke different segments of code at runtime [citation needed]. It is used throughout macOS (and its predecessor NeXTStep) as a means of customizing the behavior of program components. [3]
Dynamic binding may refer to: Dynamic binding (computing), also known as late binding; Dynamic scoping in programming languages; Dynamic binding (chemistry) See also
In computer programming, a virtual method table (VMT), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used in a programming language to support dynamic dispatch (or run-time method binding).
In programming languages, name resolution can be performed either at compile time or at runtime. The former is called static name resolution, the latter is called dynamic name resolution. A somewhat common misconception is that dynamic typing implies dynamic name resolution.
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).
A dynamic library is a library that contains functions and data that can be consumed by a computer program at run-time as loaded from a file separate from the program executable. Dynamic linking or late binding allows for using a dynamic library by linking program library references with the associated objects in the library either at load-time ...
