The purpose of dynamic dispatch is to defer the selection of an appropriate implementation until the run time type of a parameter (or multiple parameters) is known. Dynamic dispatch is different from late binding (also known as dynamic binding). Name binding associates a name with an operation. A polymorphic operation has several ...
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.
This technique achieves a similar effect to the use of virtual functions, without the costs (and some flexibility) of dynamic polymorphism. This particular use of the CRTP has been called "simulated dynamic binding" by some. [10] This pattern is used extensively in the Windows ATL and WTL libraries.
The Object Windows Library (OWL) is a C++ object-oriented application framework designed to simplify desktop application development for Windows and (some releases) OS/2. OWL was introduced by Borland in 1991 and eventually deprecated in 1997 in favor of their Visual Component Library (VCL).
late binding, because virtual function calls are not bound until the time of invocation; single dispatch (i.e., single-argument polymorphism), because virtual function calls are bound simply by looking through the vtable provided by the first argument (the this object), so the runtime types of the other arguments are completely irrelevant.
USA TODAY Network journalist Ilana Keller reported seeing a black logo after downloading a Facebook app update on her iPhone, as well as iOS update 17.6.1. Keller's phone was not in dark mode.

Multiple dispatch or multimethods is a feature of some programming languages in which a function or method can be dynamically dispatched based on the run-time (dynamic) type or, in the more general case, some other attribute of more than one of its arguments. [1]
