Example 1 with SqlPredicate

use of com.hazelcast.query.SqlPredicate in project hazelcast by hazelcast.

the class MapMBean method entrySet.

@ManagedAnnotation(value = "entrySet", operation = true)
public String entrySet(String query) {
    Set<Map.Entry> entrySet;
    if (query != null && !query.isEmpty()) {
        Predicate predicate = new SqlPredicate(query);
        entrySet = managedObject.entrySet(predicate);
    } else {
        entrySet = managedObject.entrySet();
    }
    StringBuilder buf = new StringBuilder();
    if (entrySet.size() == 0) {
        buf.append("Empty");
    } else {
        buf.append("[");
        for (Map.Entry entry : entrySet) {
            buf.append("{key:");
            buf.append(entry.getKey());
            buf.append(", value:");
            buf.append(entry.getValue());
            buf.append("}, ");
        }
        buf.replace(buf.length() - 1, buf.length(), "]");
    }
    return buf.toString();
}

Example 2 with SqlPredicate

use of com.hazelcast.query.SqlPredicate in project hazelcast by hazelcast.

    MapListener listener = new AllListener();
    map.addEntryListener(listener, new SqlPredicate("age > " + AGE_THRESHOLD), true);
    MapRandomizer mapRandomizer = new MapRandomizer(map);
    Thread t = new Thread(mapRandomizer);
    t.start();
    // let it run for 1 minute
    Thread.sleep(60000);
    mapRandomizer.setRunning(false);
    // assertions
    assertCount(ENTRIES, ENTRIES_OBSERVED, "entries");
    assertCount(EXITS, EXITS_OBSERVED, "exits");
    // dumpMap(map);
    hz.shutdown();
}

@Test
public void testValues_withPredicate() {
    int max = 27;
    IMap<Integer, String> map = client.getMap(randomString());
    Set<String> expected = new TreeSet<String>();
    for (int key = 0; key < max; key++) {
        String value = key + "value";
        map.put(key, value);
    }
    expected.add("4value");
    Collection<String> collection = map.values(new SqlPredicate("this == 4value"));
    Set<String> resultSet = new TreeSet<String>(collection);
    assertEquals(expected, resultSet);
}

Example 4 with SqlPredicate

use of com.hazelcast.query.SqlPredicate in project hazelcast by hazelcast.

@Test
public void testEntrySet_withPredicate() {
    int max = 44;
    IMap<Integer, String> map = client.getMap(randomString());
    for (int key = 0; key < max; key++) {
        String value = key + "value";
        map.put(key, value);
    }
    Set<Map.Entry<Integer, String>> entrySet = map.entrySet(new SqlPredicate("this == 1value"));
    assertEquals(1, entrySet.size());
