Sync
An iterator over a collection. Allows to sequentially access the elements. Must be closed at the end to cleanup resources.
Instances of this interface are not thread-safe and shall not be used from concurrent coroutines.
Example:
SyncIteratorJava<SyncMapJava.Item> iterator = syncMap.queryItems();
try {
SettableFuture<Boolean> hasNextFuture = SettableFuture.create();
iterator.hasNext(hasNextFuture::set);
while (hasNextFuture.get()) {
SyncMapJava.Item item = iterator.next();
System.out.println(item);
hasNextFuture = SettableFuture.create();
iterator.hasNext(hasNextFuture::set);
}
} finally {
iterator.close();

Returns true to callback if SyncIteratorJava has more elements (In other words, returns true if next() would return an element rather than throwing an exception).
