object ClassicColumnConversions extends ClassicConversions with ColumnConversions
Conversions from a org.apache.spark.sql.Column to an org.apache.spark.sql.catalyst.expressions.Expression, and vice versa.
- Note
org.apache.spark.sql.internal.ExpressionUtils#expression is a cheap alternative for org.apache.spark.sql.Column to org.apache.spark.sql.catalyst.expressions.Expression conversions. However this can only be used when the produced expression is used in a Column later on.
