Example 41 with RingbufferConfig

use of com.hazelcast.config.RingbufferConfig in project hazelcast by hazelcast.

the class RingbufferTTLTest method whenTTLEnabled_thenEventuallyRingbufferEmpties.

// when ttl is set, then eventually all the items needs to get expired.
// In this particular test we fill the ringbuffer and wait for it to expire.
// Expiration is given a 2 second martin of error. So we have a ttl of
// 10 seconds, then we expect that within 12 seconds the buffer is empty.
@Test
public void whenTTLEnabled_thenEventuallyRingbufferEmpties() throws Exception {
    int ttl = 10;
    int maximumVisibleTTL = ttl + 2;
    setup(new RingbufferConfig("foo").setTimeToLiveSeconds(ttl));
    for (int k = 0; k < ringbuffer.capacity(); k++) {
        ringbuffer.add("item" + k);
    }
    final long tail = ringbuffer.tailSequence();
    assertTrueEventually(new AssertTask() {

        assertNull(arrayRingbuffer.getItems()[k]);
