### Question:
ChainedNodeQueryResultSet extends BaseNodeQueryResultSet { @Override public SwiftResultSet convert(final SwiftMetaData metaData) { final Iterator<Row> iterator = new SwiftNode2RowIterator(this); return create(getFetchSize(), iterator, metaData); } ChainedNodeQueryResultSet(SwiftNodeOperator operator, QueryResultSet<SwiftNode> source); @Override SwiftNode getPage(); @Override boolean hasNextPage(); @Override SwiftResultSet convert(final SwiftMetaData metaData);  }### Answer:
@Test public void convert() { rs = new ChainedNodeQueryResultSet(new SwiftNodeOperator() { @Override public SwiftNode apply(SwiftNode p) { return p; } }, create()); assertNotNull(rs.convert(new SwiftMetaDataEntity())); }
