示例1: colValue

import org.apache.cassandra.cql3.ResultSet; //导入依赖的package包/类
public static String colValue(ResultSet results, List<ByteBuffer> row, int i) throws Exception {
    ByteBuffer v = row.get(i).duplicate();
    String ret = "null";
    if (v != null) {
        EnumSet<ResultSet.Flag> flags = (EnumSet<ResultSet.Flag>) CassandraUtils.readPrivate(results.metadata, "flags");
        if (flags.contains(ResultSet.Flag.NO_METADATA)) {
            ret = "0x" + ByteBufferUtil.bytesToHex(v);
        } else if (results.metadata.names.get(i).type.isCollection()) {
            ret = results.metadata.names.get(i).type.getSerializer().deserialize(v).toString();
        } else {
            ret = results.metadata.names.get(i).type.getString(v);
        }
