Schema for the row.
Number of elements in the Row.
Return a Scala Seq representing the row.
Return a Scala Seq representing the row. Elements are placed in the same order in the Seq.
Represents one row 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.To create a new Row, use
RowFactory.create()
in Java orRow.apply()
in Scala.A Row object can be constructed by providing field values. Example:
A value of a row can be accessed through both generic access by ordinal, which will incur boxing overhead for primitives, as well as native primitive access. An example of generic access by ordinal:
For 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. An example of native primitive access:In Scala, fields in a Row object can be extracted in a pattern match. Example:
