Type Members

  1. case class App(e1: Exp, e2: Exp) extends Exp with Product with Serializable

    Application of l to r.

  2. case class EquivQuery(e1: Exp, e2: Exp) extends Query with Product with Serializable

    A query that determines the alpha equivalence of two expressions.

  3. case class EvalQuery(e: Exp) extends Query with Product with Serializable

    A query that computes the value of an expression.

  4. abstract class Exp extends Positioned

    Lambda calculus expressions.

  5. case class FreeNamesQuery(e: Exp) extends Query with Product with Serializable

    A query that determines the free names in an expression.

  6. case class FreshQuery(n: Name, e: Exp) extends Query with Product with Serializable

    A query that determines whether a name is not free in an expression.

  7. case class Lam(b: Bind) extends Exp with Product with Serializable

    Lambda expression containing an abstracted binding.

  8. case class Num(i: Int) extends Exp with Product with Serializable

    Numeric expression.

  9. abstract class Query extends AnyRef

    A query that can be entered from the REPL and returns a value of type T when executed.

  10. case class SubstQuery(n: Name, e1: Exp, e2: Exp) extends Query with Product with Serializable

    A query that substitutes an expression e1 for name n in another expression e2.

  11. case class SwapQuery(tr: (Name, Name), e: Exp) extends Query with Product with Serializable
