Example 21 with IFn

use of clojure.lang.IFn in project enumerable by hraberg.

the class JavaScriptTest method interactingWithClojure.

@Test
public void interactingWithClojure() throws Exception {
    IFn star = (IFn) ClojureTest.getClojureEngine().eval("*");
    FunctionFn2 f = toFunction(LambdaClojure.toFn2(star));
    js.put("f", f);
    assertEquals(6.0, js.eval("f(2, 3)"));
}

Example 22 with IFn

use of clojure.lang.IFn in project storm by nathanmarz.

the class ClojureSpout method open.

@Override
public void open(final Map conf, final TopologyContext context, final SpoutOutputCollector collector) {
    IFn hof = Utils.loadClojureFn(_fnSpec.get(0), _fnSpec.get(1));
    try {
        IFn preparer = (IFn) hof.applyTo(RT.seq(_params));
        final Map<Keyword, Object> collectorMap = new PersistentArrayMap(new Object[] { Keyword.intern(Symbol.create("output-collector")), collector, Keyword.intern(Symbol.create("context")), context });
        List<Object> args = new ArrayList<Object>() {

            {
                add(conf);
                add(context);
                add(collectorMap);
            }
        };
        _spout = (ISpout) preparer.applyTo(RT.seq(args));
        //this is kind of unnecessary for clojure
        try {
            _spout.open(conf, context, collector);
        } catch (AbstractMethodError ame) {
        }
