Class PurityChecker.PurityResult

java.lang.Object
org.checkerframework.dataflow.util.PurityChecker.PurityResult
Enclosing class:
PurityChecker
public static class PurityChecker.PurityResult extends Object
Result of the PurityChecker. Can be queried regarding whether a given tree was side-effect-free, deterministic, or both; also gives reasons if the answer is "no".

  • Field Details

    • notSEFreeReasons

      protected final List<org.plumelib.util.IPair<Tree,String>> notSEFreeReasons
      Reasons that the referenced method is not side-effect-free.

    • notDetReasons

      protected final List<org.plumelib.util.IPair<Tree,String>> notDetReasons
      Reasons that the referenced method is not deterministic.

    • notBothReasons

      protected final List<org.plumelib.util.IPair<Tree,String>> notBothReasons
      Reasons that the referenced method is not side-effect-free and deterministic.

    • kinds

      protected EnumSet<Pure.Kind> kinds
      Contains all the varieties of purity that the expression has. Starts out with all varieties, and elements are removed from it as violations are found.

  • Constructor Details

    • PurityResult

      public PurityResult()

  • Method Details

    • getKinds

      public EnumSet<Pure.Kind> getKinds()
      Return the kinds of purity that the method has.
      Returns:
      the kinds of purity that the method has

    • isPure

      public boolean isPure(EnumSet<Pure.Kind> otherKinds)
      Is the method pure w.r.t. a given set of kinds?
      Parameters:
      otherKinds - the varieties of purity to check
      Returns:
      true if the method is pure with respect to all the given kinds

      Get the reasons why the method is not both side-effect-free and deterministic.
      Returns:
      the reasons why the method is not both side-effect-free and deterministic

    • addNotBothReason

      public void addNotBothReason(Tree t, String msgId)
