GenerateMutableProjection

object GenerateMutableProjection extends CodeGenerator[Seq[Expression], MutableProjection]

Generates byte code that produces a InternalRow object that can update itself based on a new input InternalRow for a fixed set of Expressions. It exposes a target method, which is used to set the row that will be updated. The internal InternalRow object created internally is used only when target is not used.
