lazymap

Take the greediness out of maps.

Installation

Use it with Leiningen like so:

[fr.grunwald/lazymap "3.1.0"]

Description

This is a (small) fork from Kotorak's lazymap library. LazyMap is a transparent wrapper around the map types of Clojure. It works similar to lazy-seq for sequences: the value associated with a key via lazy-assoc is not evaluated until it is actually accessed. So if the value is dissoc'd before it is accessed the code necessary to generate the value is not executed at all.

Usage

user=> (use 'lazymap.core)
nil
user=> (def m (lazy-hash-map :x (do (println :a) :y)))
#'user/m
user=> (get m :x)
:a
:y
user=> (get m :x)
:y
