Protocols and Multimethods for Polymorphism
Clojure offers two flexible polymorphism tools that complement macros and modular design. This lesson teaches protocols and multimethods for extensible, decoupled code.
Polymorphism in Clojure
Clojure separates data from behavior. Protocols and multimethods let you dispatch behavior without classes or inheritance.
Defining a Protocol
A defprotocol names a set of method signatures, like an interface.
