Substream is a small library for constructing subclasses of
java.io.InputStream from standard Clojure functions.
This is necessary due to the limitations of subclassing in clojure.
To install, add the following to your project :dependencies:
[substream "0.1.0"]
The substream.core/input-stream function will construct a new
InputStream instance from a zero-argument Clojure function. The
function can returns a value representing a byte from the stream. The
return value may be an integer, byte or nil if the stream has ended.
(require '[substream.core :as substream])
(def data
(ref (seq (.getBytes "Hello World"))))
(def stream
(substream/input-stream
#(dosync
(when (seq @state)
(let [value (first @state)]
(alter state next)
value))))Copyright © 2014 James Reeves
