API for java-utils
- ()
by Stuart Halloway, Stephen C. Gilardi, Shawn Hoover, Perry Trolard, Stuart Sierra
Usage:
(ns your-namespace
(:require clojure.contrib.java-utils))
Overview
A set of utilties for dealing with Java stuff like files and properties.
Design goals:
(1) Ease-of-use. These APIs should be convenient. Performance is secondary.
(2) Duck typing. I hate having to think about the difference between
a string that names a file, and a File. Ditto for a ton of other
wrapper classes in the Java world (URL, InternetAddress). With these
APIs you should be able to think about domain equivalence, not type
equivalence.
(3) No bossiness. I am not marking any of these functions as private
the docstrings will tell you the intended usage but do what works for you.
Feedback welcome!
If something in this module violates the principle of least surprise, please
let me (Stu) and the Clojure community know via the mailing list.
