Filter

case class Filter (values: Array[IntVar], cond: (Int) ⇒ Boolean) extends IntSetInvariant with Product with Serializable

{ i in index(values) | cond(values[i] }

values

is an array of IntVar

cond

is a function that selects values to be includes in the output set. This cond function cannot depend on any IntVar, as updates to these IntVars will not trigger propagation of this invariant.
