Clojure (Clojure API)

java.lang.Object
- clojure.java.api.Clojure

```
public class Clojure
extends java.lang.Object
```
The Clojure class provides a minimal interface to bootstrap Clojure access from other JVM languages. It provides:
1. The ability to use Clojure's namespaces to locate an arbitrary var, returning the var's IFn interface.
2. A convenience method read for reading data using Clojure's edn reader
To lookup and call a Clojure function:
```
 IFn plus = Clojure.var("clojure.core", "+");
 plus.invoke(1, 2);
```
Functions in clojure.core are automatically loaded. Other namespaces can be loaded via require:
```
 IFn require = Clojure.var("clojure.core", "require");
 require.invoke(Clojure.read("clojure.set"));
```
IFns can be passed to higher order functions, e.g. the example below passes inc to map:
```
 IFn map = Clojure.var("clojure.core", "map");
 IFn inc = Clojure.var("clojure.core", "inc");
 map.invoke(inc, Clojure.read("[1 2 3]"));
```
