Examples with QueryArgs utils.query.QueryArgs used on opensource projects

Example 1 with QueryArgs

use of utils.query.QueryArgs in project jdchain-core by blockchain-jd-com.

@Override
public TypedKVEntry[] getDataEntries(String address, int fromIndex, int count) {
    DataAccountSet dataAccountSet = ledgerQuery.getDataAccountSet();
    DataAccount dataAccount = dataAccountSet.getAccount(Bytes.fromBase58(address));
    QueryArgs queryArgs = QueryUtils.calFromIndexAndCount(fromIndex, count, (int) dataAccount.getDataset().getDataCount());
    SkippingIterator<DataEntry<String, TypedValue>> iterator = ((IteratorDataset) dataAccount.getDataset()).kvIterator();
    iterator.skip(queryArgs.getFrom());
    TypedKVEntry[] typedKVEntries = iterator.next(queryArgs.getCount(), TypedKVEntry.class, entry -> new TypedKVData(entry.getKey(), entry.getVersion(), entry.getValue()));
    return typedKVEntries;
}
