### Question:
OFRowGroupListMetadata { private OFRowGroupListMetadata() { } private  OFRowGroupListMetadata();  OFRowGroupListMetadata(String deviceId); static OFRowGroupListMetadata deserializeFrom(InputStream inputStream); static OFRowGroupListMetadata deserializeFrom(ByteBuffer buffer); void addSeriesListMetaData(OFSeriesListMetadata timeSeries); List<OFSeriesListMetadata> getSeriesList(); @Override String toString(); String getdeviceId(); int serializeTo(OutputStream outputStream); int serializeTo(ByteBuffer buffer);  }### Answer:
@Test public void testOFRowGroupListMetadata() throws Exception { OFRowGroupListMetadata ofRowGroupListMetadata = OverflowTestHelper .createOFRowGroupListMetadata(); serialize(ofRowGroupListMetadata); OFRowGroupListMetadata deOfRowGroupListMetadata = deSerialized(); OverflowUtils.isOFRowGroupListMetadataEqual(ofRowGroupListMetadata, deOfRowGroupListMetadata); }
