A simple wrapper for the fressian binary encoding protocol that makes it easy to use from and for clojure. No attention paid to performance yet.
Support clojure keywords, symbols, and maps in addition to the default fressian options.
:dependencies [fressian-clojure "0.2.0"] (:use [org.fressian.clojure :only [decode encode add-handler]])
Very simple to use
(def byte-array (fr/encode obj) ;; returns byte (fr/decode byte-array) ;; returns obj
Can add your own global handlers for new types:
(fr/add-handler org.type.MyType "mytag" <writer> <reader>)
This is a critical facility if you wish to retain the types of defrecords or deftype values during decoding. For defrecords, the decoded result is a plain map. See the file clojure.clj for examples of writers and readers and other methods of interest.
- Should be reasonably efficient, but no guarantees about encoding/decoding optimality, especially for collection types
- Default serializer handlers do not distinguish between array and hash maps
- Records are deserialized as maps by default (see above)
- Structs are always deserialized as maps
- Collection metadata is ignored
- Functions cannot be serialized
- No support for persistent queues yet
