orc.runtime.values
Class ListValue

java.lang.Object
  orc.runtime.values.Value
      orc.runtime.values.ListValue

All Implemented Interfaces:

java.lang.Iterable, Future

Direct Known Subclasses:

ConsValue, NilValue

public abstract class ListValue
extends Value
implements java.lang.Iterable

Common ancestor for ConsValue and NilValue. Unlike scheme, the Cons constructor does not allow you to create a degenerate cons where the tail is not a list, so we can guarantee that all Conses actually have a list structure. (If you want a degenerate cons, just use a tuples.)
