Examples with ConcurrentHashMap org.eclipse.collections.impl.map.mutable.ConcurrentHashMap used on opensource projects

Example 1 with ConcurrentHashMap

use of org.eclipse.collections.impl.map.mutable.ConcurrentHashMap in project eclipse-collections by eclipse.

the class SerialParallelLazyPerformanceTest method forEach.

private void forEach(FastList<Integer> collection) {
    MutableList<Runnable> runnables = FastList.newList();
    runnables.add(() -> this.basicSerialForEachPerformance(collection, SERIAL_RUN_COUNT));
    int cores = Runtime.getRuntime().availableProcessors();
    ExecutorService service = Executors.newFixedThreadPool(cores);
    runnables.add(() -> {
        MutableMap<Integer, Boolean> map = new ConcurrentHashMap<>();
        this.basicParallelLazyForEachPerformance(collection, "Lambda", item -> map.put(item, Boolean.TRUE), PARALLEL_RUN_COUNT, cores, service);
    });
    runnables.add(() -> {
        MutableMap<Integer, Boolean> map = new ConcurrentHashMap<>();
        this.basicParallelLazyForEachPerformance(collection, "Procedure", (Procedure<Integer>) each -> map.put(each, Boolean.TRUE), PARALLEL_RUN_COUNT, cores, service);
    });
    runnables.add(() -> {
        MutableMap<Integer, Boolean> map = new ConcurrentHashMap<>();
        this.basicJava8ParallelLazyForEachPerformance(collection, "Lambda", item -> map.put(item, Boolean.TRUE), PARALLEL_RUN_COUNT);
    });
    List<Integer> arrayList = new ArrayList<>(collection);
    runnables.add(() -> {
        MutableMap<Integer, Boolean> map = new ConcurrentHashMap<>();
        this.basicJava8ParallelLazyForEachPerformance(arrayList, "Lambda", item -> map.put(item, Boolean.TRUE), PARALLEL_RUN_COUNT);
    });
    runnables.add(() -> {
        MutableMap<Integer, Boolean> map = new ConcurrentHashMap<>();
        this.basicJava8ParallelLazyForEachPerformance(arrayList, "Consumer", each -> map.put(each, Boolean.TRUE), PARALLEL_RUN_COUNT);
    });
    this.shuffleAndRun(runnables);
    service.shutdown();
    try {
        service.awaitTermination(1, TimeUnit.MINUTES);
    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    }
}

Example 2 with ConcurrentHashMap

use of org.eclipse.collections.impl.map.mutable.ConcurrentHashMap in project eclipse-collections by eclipse.

the class ConcurrentHashMapTest method newWith.

@Override
public <T> MutableMap<Object, T> newWith(T... elements) {
    Random random = new Random(CURRENT_TIME_MILLIS);
    MutableMap<Object, T> result = new ConcurrentHashMap<>();
    for (T each : elements) {
        assertNull(result.put(random.nextDouble(), each));
    }
    return result;
}
