Series

trait Series extends AnyRef

Represents one series of output from a relational operator. Allows both generic access by ordinal, which will incur boxing overhead for primitives, as well as native primitive access.

It is invalid to use the native primitive interface to retrieve a value that is null, instead a user must check isNullAt before attempting to retrieve a value that might be null.

Abstract Value Members

  1. abstract def copy(): Series

    Make a copy of the current Series object.

  2. abstract def get(i: Int): Any

    Returns the value at position i.

    Returns the value at position i. If the value is null, null is returned.

  3. abstract def length: Int

    Number of elements in the Series.

  17. def getAs[T](fieldName: String): T

    Returns the value of a given fieldName.

    Returns the value of a given fieldName. For primitive types if value is null it returns 'zero value' specific for primitive ie. 0 for Int - use isNullAt to ensure that value is not null

    Exceptions thrown
    ClassCastException

    when data type does not match.

    IllegalArgumentException

    when fieldName do not exist.

    UnsupportedOperationException

    when schema is not defined.

  18. def getAs[T](i: Int): T

    Returns the value at position i.

    Returns the value at position i. For primitive types if value is null it returns 'zero value' specific for primitive ie. 0 for Int - use isNullAt to ensure that value is not null

    Exceptions thrown
    ClassCastException

    when data type does not match.

    Checks whether the value at position i is missing (null or Double.NaN) if the position is valid, otherwise treated as missing too.

  28. def isNullAt(i: Int): Boolean

    Checks whether the value at position i is null.
