Data - Support

This page summarizes some of Clojure's key concepts regarding data-reated support mechanisms. It also provides links to more detailed information.

Datatypes

The datatype features - deftype, defrecord, and reify - provide the mechanism for defining implementations of abstractions, and in the case of reify, instances of those implementations. The abstractions themselves are defined by either protocols or interfaces. A datatype provides a host type ... with some structure ..., and optional in-type implementations of abstraction methods. They support, in a relatively clean manner, access to the highest-performance primitive representation and polymorphism mechanisms of the host.

Garbage Collection

Clojure relies on the JVM (Java Virtual Machine) to perform any needed garbage collection (ie, reclamation of memory from unused objects). Clojure's implementation of persistence generates a substantial amount of incidental garbage (eg, intermediate nodes), so efficient garbage collection is very important to performance.
