Questions tagged [dispatch]

Dynamic dispatch (also known as dynamic binding) is the process of mapping a message to a specific sequence of code (method) at runtime. This is done to support the cases where the appropriate method cannot be determined at compile-time (i.e. statically).

Dynamic dispatch is only used for code invocation and not for other binding processes (such as for global variables) and the name is normally only used to describe a language feature where a runtime decision is required to determine which code to invoke.

This Object-Oriented feature allows substituting a particular implementation using the same interface, and therefore it enables polymorphism.
