  10. val e: E

    The entity.

    The entity. E.g., a class, method or field. In general, it is recommended to use entities that stand for specific elements in the code, but which are not the concrete source code entities themselves. This greatly facilitates associating properties with entities where the respective code is not available. For example, by using an object which acts as a representative for a concrete method it is possible to associate (predetermined) properties with (selected) library methods even if those methods are not part of the analysis.

    Note

    Entities have to implement equals/hashCode methods which are very efficient, because entity based comparisons happen very frequently!

  36. def ub: Nothing

    Returns the upper bound of the property if it is available – hasUBP has to be true – otherwise an UnsupportedOperationException is thrown.

    Returns the upper bound of the property if it is available – hasUBP has to be true – otherwise an UnsupportedOperationException is thrown.

    The upper bound always models the best/most precise result w.r.t. the underlying lattice. Here, "best" means that the set of potentially reachable states/instructions that the analyzed program can ever assume is potentially smaller when compared to a worse property.

    The upper bound models the sound and precise result under the assumption that the properties of all explicitly and implicitly relevant entities is as last queried or implicitly assumed. I.e., unless a dependee is updated the upper bound represents the correct and most precise result.

    The lower bound models the worst case property that a specific entity can have under the assumption that all other relevant properties will get their worst properties. This can – but does not have to be – the underlying lattice's bottom value. The lower bound is generally helpful for client analyses to determine final results quicker. For example, imagine the following code:

    def f(a : AnyRef) : Unit = a match {
      case a : List[_] => if (a.exists( _ == null)) throw  new IllegalArgumentException
      case _ => throw new UnknownError
    }
    def m(){
      try {
        f(List(1,2,3))
      } catch {
        case nfe:  NumberFormatException => ...
      }
    }

    In that case – assuming we do not perform context sensitive analyses – if the lower bound for f for the set of thrown exceptions is determined to be Set(IllegalArgumentException,UnkownError), then the catch of the NumberFormatException can be ruled out and a final result for m can be computed.
