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.
Despacho múltiplo (ou multimétodos) é a característica de algumas linguagens orientadas a objeto em que uma função ou método pode ser lançado dinamicamente baseado no tipo de tempo de execução (dinâmico) de mais de um de seus argumentos.
11 de ago. de 2018 · Multiple dispatch allows for subtyping polymorphism of arguments for method calls. Single dispatch also allows for a more limited kind of polymorphism (using the same method name for objects that implement the same interface or inherit the same base class).
In software engineering, double dispatch is a special form of multiple dispatch, and a mechanism that dispatches a function call to different concrete functions depending on the runtime types of two objects involved in the call.
Dynamic dispatch contrasts with static dispatch, in which the implementation of a polymorphic operation is selected at compile time. 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.
10 de jan. de 2021 · Multiple dispatch enables higher order expressivity by dispatching on combinations of types of function inputs. Multiple dispatch also promotes code reuse kudos to these two properties: We can define new types on which existing operations can be applied
3 de abr. de 2021 · Multiple dispatch is a way that we can apply function calls as properties of types. In other words, we can redefine the same function over and over again, but just plan for different types to be passed through it in order to essentially recreate the method to handle a new type.
