  • Method Details

    • unmaskList

      protected static final @NonNull com.google.common.collect.ImmutableList<? extends @NonNull EffectiveStatement<?,?>> unmaskList(@NonNull Object masked)
      Utility method for recovering singleton lists squashed by maskList(ImmutableList).
      Parameters:
      masked - list to unmask
      Returns:
      Unmasked list
      Throws:
      NullPointerException - if masked is null
      ClassCastException - if masked object does not match EffectiveStatement

    • maskList

      protected static final @NonNull Object maskList(com.google.common.collect.ImmutableList<?> list)
      Utility method for squashing singleton lists into single objects. This is a CPU/mem trade-off, which we are usually willing to make: for the cost of an instanceof check we can save one object and re-create it when needed. The inverse operation is #unmaskSubstatements(Object)}.
      Parameters:
      list - list to mask
      Returns:
      Masked list
      Throws:
      NullPointerException - if list is null

    • unmaskList

      protected static final <T> @NonNull com.google.common.collect.ImmutableList<T> unmaskList(@NonNull Object masked, @NonNull Class<T> type)
      Utility method for recovering singleton lists squashed by maskList(ImmutableList).
      Parameters:
      masked - list to unmask
      Returns:
      Unmasked list
      Throws:
      NullPointerException - if any argument is null
      ClassCastException - if masked object does not match expected class

    • maskSet

      protected static final @NonNull Object maskSet(com.google.common.collect.ImmutableSet<?> set)

    • unmaskSet
