Examples with Column org.apache.cassandra.db.Column used on opensource projects

Example 6 with Column

use of org.apache.cassandra.db.Column in project eiger by wlloyd.

the class SSTableExportTest method testEscapingDoubleQuotes.

@Test
public void testEscapingDoubleQuotes() throws IOException {
    File tempSS = tempSSTableFile("Keyspace1", "ValuesWithQuotes");
    ColumnFamily cfamily = ColumnFamily.create("Keyspace1", "ValuesWithQuotes");
    SSTableWriter writer = new SSTableWriter(tempSS.getPath(), 2);
    // Add rowA
    cfamily.addColumn(null, new Column(ByteBufferUtil.bytes("data"), UTF8Type.instance.fromString("{\"foo\":\"bar\"}")));
    writer.append(Util.dk("rowA"), cfamily);
    cfamily.clear();
    SSTableReader reader = writer.closeAndOpenReader();
    // Export to JSON and verify
    File tempJson = File.createTempFile("ValuesWithQuotes", ".json");
    SSTableExport.export(reader, new PrintStream(tempJson.getPath()), new String[0]);
    JSONObject json = (JSONObject) JSONValue.parse(new FileReader(tempJson));
    JSONArray rowA = (JSONArray) json.get(asHex("rowA"));
    JSONArray data = (JSONArray) rowA.get(0);
    assert hexToBytes((String) data.get(0)).equals(ByteBufferUtil.bytes("data"));
    assert data.get(1).equals("{\"foo\":\"bar\"}");
}

Example 7 with Column

use of org.apache.cassandra.db.Column in project eiger by wlloyd.

the class CassandraStorage method columnToTuple.

private Tuple columnToTuple(ByteBuffer name, IColumn col, CfDef cfDef) throws IOException {
    Tuple pair = TupleFactory.getInstance().newTuple(2);
    List<AbstractType> marshallers = getDefaultMarshallers(cfDef);
    Map<ByteBuffer, AbstractType> validators = getValidatorMap(cfDef);
    setTupleValue(pair, 0, marshallers.get(0).compose(name));
    if (col instanceof Column) {
        // standard
        if (validators.get(name) == null)
            setTupleValue(pair, 1, marshallers.get(1).compose(col.value()));
        else
            setTupleValue(pair, 1, validators.get(name).compose(col.value()));
        return pair;
    }
    // super
    ArrayList<Tuple> subcols = new ArrayList<Tuple>();
    for (IColumn subcol : col.getSubColumns()) subcols.add(columnToTuple(subcol.name(), subcol, cfDef));
    pair.set(1, new DefaultDataBag(subcols));
    return pair;
