API for java-utils
- ()
by Stuart Halloway, Stephen C. Gilardi, Shawn Hoover, Perry Trolard, Stuart Sierra
clojure-contrib is now deprecated
clojure-contrib is no longer being developed or maintained.
Rather than a single, monolithic, contributions library, Clojure now has
a set of separate libraries for each unit of functionality. The libraries
are in the Clojure GitHub organization at
https://github.com/clojure.
API documentation of the libraries can be found at
https://clojure.github.io.
If you're looking for a specific function or namespace from the old
clojure-contrib, see
"Where Did Clojure.Contrib Go".
Full namespace name:
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.

Public Variables and Functions
as-file
multimethod
This library, clojure-contrib, is deprecated. See here for more information.
No usage documentation available
Interpret a String or a java.io.File as a File. Building block
for clojure.contrib.java-utils/file, which you should prefer
in most cases.
Deprecated since clojure-contrib version 1.2
Source
as-properties
function
This library, clojure-contrib, is deprecated. See here for more information.
Usage: (as-properties m)
Convert any seq of pairs to a java.utils.Properties instance.
Uses as-str to convert both keys and values into strings.
Source
as-str
function
This library, clojure-contrib, is deprecated. See here for more information.
Usage: (as-str)
(as-str x)
(as-str x & ys)
Like clojure.core/str, but if an argument is a keyword or symbol,
its name will be used instead of its literal representation.
Example:
(str :foo :bar) ;;=> ":foo:bar"
(as-str :foo :bar) ;;=> "foobar"
Note that this does not apply to keywords or symbols nested within
data structures; they will be rendered as with str.
Example:
(str {:foo :bar}) ;;=> "{:foo :bar}"
(as-str {:foo :bar}) ;;=> "{:foo :bar}"
Deprecated since clojure-contrib version 1.2
