    This is our unbound variables analysis.

    This is our unbound variables analysis. We want to detect, for a lambda-calculus program, which evaluated variables may be unbound. We represent this by a set of lambda expressions, which is the lattice computed by this analysis: Set[LamExp]. This class defines how to update the current state of the analysis.

Value Members

  1. def error(err: SemanticError, current: Set[LamExp]): Set[LamExp]

    The checking for unbound variables could be done here, by looking at the "err" parameter, which is UnboundVariable(name).

    The checking for unbound variables could be done here, by looking at the "err" parameter, which is UnboundVariable(name). But that's not how we proceed for this analysis, because we want the full expression (and also, we want to show how to describe the analysis in terms of stepEval).

  6. def toParArray: ParArray[T]
    Implicit
    This member is added by an implicit conversion from UnboundVariablesAnalysis[Abs, Addr, Time] to CollectionsHaveToParArray[UnboundVariablesAnalysis[Abs, Addr, Time], T] performed by method CollectionsHaveToParArray in scala.collection.parallel. This conversion will take place only if an implicit value of type (UnboundVariablesAnalysis[Abs, Addr, Time]) ⇒ GenTraversableOnce[T] is in scope.
