Examples with AFn clojure.lang.AFn used on opensource projects

Example 1 with AFn

use of clojure.lang.AFn in project data.int-map by clojure.

the class IntSet method range.

public ISet range(final long epoch, final long min, final long max) {
    if (max < min) {
        return new IntSet(leafSize);
    }
    if (mapKey(min) == mapKey(max)) {
        ISet set = (ISet) map.get(mapKey(min), null);
        set = set == null ? null : set.range(epoch, leafOffset(min), leafOffset(max));
        return set == null ? new IntSet(leafSize) : new IntSet(leafSize, log2LeafSize, Nodes.Empty.EMPTY.assoc(mapKey(min), epoch, null, set));
    }
    INode mapPrime = map.range(mapKey(min), mapKey(max));
    mapPrime = mapPrime == null ? Nodes.Empty.EMPTY : mapPrime.update(mapKey(min), epoch, new AFn() {

        public Object invoke(Object v) {
            return v != null ? ((ISet) v).range(epoch, leafOffset(min), leafSize) : null;
        }
    }).update(mapKey(max), epoch, new AFn() {

        public Object invoke(Object v) {
            return v != null ? ((ISet) v).range(epoch, 0, leafOffset(max)) : null;
        }
    });
    return new IntSet(leafSize, log2LeafSize, mapPrime);
}

Example 2 with AFn

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

the class SystemBolt method prepare.
