use of org.neo4j.helpers.collection.FilteringIterable in project neo4j by neo4j.

the class DisconnectLeaderScenario method oneIteration.

private long oneIteration(long leaderStabilityMaxTimeMillis) throws InterruptedException, TimeoutException {
    List<RaftMachine> rafts = fixture.rafts.stream().map(Fixture.RaftFixture::raftMachine).collect(toList());
    MemberId oldLeader = ElectionUtil.waitForLeaderAgreement(rafts, leaderStabilityMaxTimeMillis);
    long startTime = System.currentTimeMillis();
    fixture.net.disconnect(oldLeader);
    MemberId newLeader = ElectionUtil.waitForLeaderAgreement(new FilteringIterable<>(rafts, raft -> !raft.identity().equals(oldLeader)), leaderStabilityMaxTimeMillis);
    // this should be guaranteed by the waitForLeaderAgreement call
    assert !newLeader.equals(oldLeader);
    return System.currentTimeMillis() - startTime;
}
