Example 31 with ArrayBlockingQueue

use of java.util.concurrent.ArrayBlockingQueue in project mapdb by jankotek.

the class ArrayBlockingQueueTest method testContains.

/**
     * contains(x) reports true when elements added but not yet removed
     */
public void testContains() {
    ArrayBlockingQueue q = populatedQueue(SIZE);
    for (int i = 0; i < SIZE; ++i) {
        assertTrue(q.contains(new Integer(i)));
        assertEquals(i, q.poll());
        assertFalse(q.contains(new Integer(i)));
    }
}

Example 32 with ArrayBlockingQueue

use of java.util.concurrent.ArrayBlockingQueue in project mapdb by jankotek.

the class ArrayBlockingQueueTest method testClear.

/**
     * clear removes all elements
     */

    q.clear();
    assertTrue(q.isEmpty());
    assertEquals(0, q.size());

}

Example 33 with ArrayBlockingQueue

use of java.util.concurrent.ArrayBlockingQueue in project mapdb by jankotek.
