Returns the value at position i. If the value is null, null is returned. The following is a mapping between Spark SQL types and return types:

BooleanType -> java.lang.Boolean
ByteType -> java.lang.Byte
ShortType -> java.lang.Short
IntegerType -> java.lang.Integer
LongType -> java.lang.Long
FloatType -> java.lang.Float
DoubleType -> java.lang.Double
StringType -> String
DecimalType -> java.math.BigDecimal

DateType -> java.sql.Date if spark.sql.datetime.java8API.enabled is false
DateType -> java.time.LocalDate if spark.sql.datetime.java8API.enabled is true

TimestampType -> java.sql.Timestamp if spark.sql.datetime.java8API.enabled is false
TimestampType -> java.time.Instant if spark.sql.datetime.java8API.enabled is true

BinaryType -> byte array
ArrayType -> scala.collection.Seq (use getList for java.util.List)
MapType -> scala.collection.Map (use getJavaMap for java.util.Map)
StructType -> org.apache.spark.sql.Row
