An abstract base class for DeclaredStatement implementations. It provides various further stateless and stateful subclasses.

  • Constructor Details

    • AbstractDeclaredStatement

      public AbstractDeclaredStatement()

  • Method Details

    • declaredSubstatements

      public ImmutableList<? extends DeclaredStatement<?>> declaredSubstatements()
      Description copied from interface: DeclaredStatement
      Returns collection of explicitly declared child statements, while preserving its original ordering from original source.
      Returns:
      Collection of statements, which were explicitly declared in source of model.

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • toString

      public final String toString()
      Overrides:
      toString in class Object

    • addToStringAttributes

      protected MoreObjects.ToStringHelper addToStringAttributes(MoreObjects.ToStringHelper helper)

    • maskList

      protected static final @NonNull Object maskList(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 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(ImmutableSet<?> set)

    • unmaskSet

      protected static final <T> @NonNull ImmutableSet<T> unmaskSet(@NonNull Object masked, @NonNull Class<T> type)
