    for (Model item : items) {
        if (modelName.equals(item.getClass().getSimpleName()) && predicate.evaluate(item)) {
            // TODO, add tests for new query method.
            result.add(item);
        }
    }
    onSuccess.accept(result.iterator());
}

Example 2 with QueryPredicate

@SuppressWarnings("unchecked")
@Override
public <T extends Model> void query(@NonNull final Class<T> itemClass, @NonNull final QueryOptions options, @NonNull final Consumer<Iterator<T>> onSuccess, @NonNull final Consumer<DataStoreException> onError) {
