lazymap – take the strictness out of maps


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.


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

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for

Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
