abstract class MutableValue extends Serializable

A parent class for mutable container objects that are reused when the values are changed, resulting in less garbage. These values are held by a SpecificInternalRow.

The following code was roughly used to generate these objects:

val types = "Int,Float,Boolean,Double,Short,Long,Byte,Any".split(",")
types.map {tpe =>
s"""
final class Mutable$tpe extends MutableValue {
  var value: $tpe = 0
  def boxed = if (isNull) null else value
  def update(v: Any) = value = {
    isNull = false
    v.asInstanceOf[$tpe]
  }
  def copy() = {
    val newCopy = new Mutable$tpe
    newCopy.isNull = isNull
    newCopy.value = value
    newCopy
  }
}"""
}.foreach(println)

types.map { tpe =>
s"""
  override def set$tpe(ordinal: Int, value: $tpe): Unit = {
    val currentValue = values(ordinal).asInstanceOf[Mutable$tpe]
    currentValue.isNull = false
    currentValue.value = value
  }

  override def get$tpe(i: Int): $tpe = {
    values(i).asInstanceOf[Mutable$tpe].value
  }"""
