final class CassandraRow extends ScalaGettableData with Serializable

Represents a single row fetched from Cassandra. Offers getters to read individual fields by column name or column index. The getters try to convert value to desired type, whenever possible. Most of the column types can be converted to a String. For nullable columns, you should use the getXXXOption getters which convert nulls to None values, otherwise a NullPointerException would be thrown.

All getters throw an exception if column name/index is not found. Column indexes start at 0.

If the value cannot be converted to desired type, com.datastax.spark.connector.types.TypeConversionException is thrown.

Recommended getters for Cassandra types:

- ascii: getString, getStringOption - bigint: getLong, getLongOption - blob: getBytes, getBytesOption - boolean: getBool, getBoolOption - counter: getLong, getLongOption - decimal: getDecimal, getDecimalOption - double: getDouble, getDoubleOption - float: getFloat, getFloatOption - inet: getInet, getInetOption - int: getInt, getIntOption - text: getString, getStringOption - timestamp: getDate, getDateOption - timeuuid: getUUID, getUUIDOption - uuid: getUUID, getUUIDOption - varchar: getString, getStringOption - varint: getVarInt, getVarIntOption - list: getList[T] - set: getSet[T] - map: getMap[K, V]

Collection getters getList, getSet and getMap require to explicitly pass an appropriate item type:

row.getList[String]("a_list")
row.getList[Int]("a_list")
row.getMap[Int, String]("a_map")

Generic get allows to automatically convert collections to other collection types. Supported containers: - scala.collection.immutable.List - scala.collection.immutable.Set - scala.collection.immutable.TreeSet - scala.collection.immutable.Vector - scala.collection.immutable.Map - scala.collection.immutable.TreeMap - scala.collection.Iterable - scala.collection.IndexedSeq - java.util.ArrayList - java.util.HashSet - java.util.HashMap

Example:

row.get[List[Int]]("a_list")
row.get[Vector[Int]]("a_list")
row.get[java.util.ArrayList[Int]]("a_list")
row.get[TreeMap[Int, String]]("a_map")

Timestamps can be converted to other Date types by using generic get. Supported date types: - java.util.Date - java.sql.Date
