Class RemoveIn

java.lang.Object
  net.cscott.sdr.calls.transform.TransformVisitor<Fraction>
      net.cscott.sdr.calls.transform.RemoveIn

public class RemoveIn
extends TransformVisitor<Fraction>

Remove Ins from a call tree by pushing them down and adjusting Prim timing. We use the "inherent" times given by a BeatCounter to proportionally allocate the available beats from the top down.

Tests:

Eliminate In from 1/2 DOSADO:

js> importPackage(net.cscott.sdr.calls.ast)
js> a = Apply.makeApply("_fractional", Apply.makeApply("1/2"), Apply.makeApply("dosado"))
(Apply _fractional (Apply 1/2) (Apply dosado))
js> def = a.expand()
(In 3 (Opt (From [FACING DANCERS] (Seq (Prim -1, 1, none, 1, SASHAY_START) (Prim 1, 1, none, 1, SASHAY_FINISH)))))
js> RemoveIn.removeIn(def)
(Opt (From [FACING DANCERS] (Seq (Prim -1, 1, none, 1 1/2, SASHAY_START) (Prim 1, 1, none, 1 1/2, SASHAY_FINISH))))
