case class ExprCode(code: String, isNull: String, value: String) extends Product with Serializable

Java source for evaluating an Expression given a InternalRow of input.

code

The sequence of statements required to evaluate the expression. It should be empty string, if isNull and value are already existed, or no code needed to evaluate them (literals).

isNull

A term that holds a boolean value representing whether the expression evaluated to null.

value

A term for a (possibly primitive) value of the result of the evaluation. Not valid if isNull is set to true.
