Stacker

trait Stacker[I, J, O] extends AnyRef

A Stacker operates on two input Index instances and produces a new output Index whose entries are drawn from the Cartesian product of the elements of the original indexes, and whose ordering is likewise specified by the original orderings. For instance,

  Index[Int](1,2) stack Index[Char]('a','b')

results in

  Index[(Int, Char)]((1,'a'), (1,'b'), (2,'a'), (2,'b'))

whereas

  Index[(Char, Int)](('x',1), ('y',2)) stack Index[Char]('a','b')

results in

  Index[(Char, Int, Char)](('x',1,'a'), ('x',1,'b'), ('y',2,'a'), ('y',2,'b'))
I

Type of the elements of the left index

J

Type of the elements of the right index

O

Type of the elements of the output index
