示例1: events

@Test
public void events() throws Exception {
// Check that we get the right events at the right time.
final List<List<ECKey>> listenerKeys = Lists.newArrayList();
long secs = 1389353062L;
chain = new DeterministicKeyChain(ENTROPY, "", secs);
chain.addEventListener(new AbstractKeyChainEventListener() {
@Override
public void onKeysAdded(List<ECKey> keys) {
listenerKeys.add(keys);
}
}, Threading.SAME_THREAD);
assertEquals(0, listenerKeys.size());
chain.setLookaheadSize(5);
assertEquals(0, listenerKeys.size());
ECKey key = chain.getKey(KeyChain.KeyPurpose.CHANGE);
assertEquals(1, listenerKeys.size()); // 1 event
final List<ECKey> firstEvent = listenerKeys.get(0);
assertEquals(1, firstEvent.size());
assertTrue(firstEvent.contains(key)); // order is not specified.
listenerKeys.clear();

final int lookaheadThreshold = chain.getLookaheadThreshold() + chain.getLookaheadSize();
for (int i = 0; i < lookaheadThreshold; i++)

assertEquals(1, listenerKeys.size()); // 1 event
