/**
     * entrySet.toArray contains all entries
     */
@Test
public void testEntrySetToArray() {
    ConcurrentMap map = map5();
    Set s = map.entrySet();
    Object[] ar = s.toArray();
    assertEquals(5, ar.length);
    for (int i = 0; i < 5; ++i) {
        assertTrue(map.containsKey(((Map.Entry) (ar[i])).getKey()));
        assertTrue(map.containsValue(((Map.Entry) (ar[i])).getValue()));
    }
}

Example 22 with ConcurrentMap

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

     * replace value fails when the given key not mapped to expected value
     */
@Test
public void testReplaceValue() {
    ConcurrentMap map = map5();
    assertEquals("A", map.get(one));
    assertFalse(map.replace(one, "Z", "Z"));
    assertEquals("A", map.get(one));
}

Example 23 with ConcurrentMap
