      Description copied from interface: ElementSet
      For each element in this set, adds an edge to the given element.
      Specified by:
      addNext in interface ElementSet

    • contains

      public boolean contains(ElementSet rhs)
      Description copied from interface: ElementSet
      Doesn't have to be strict (it's OK for this method to return false when it's actually true) since this is used just for optimization. (Erring on the other side is NG)
      Specified by:
      contains in interface ElementSet

    • iterator

      @Deprecated public Iterator<Element> iterator()
      Deprecated.
      if you statically call this method, there's something wrong.
      Just to satisfy the ElementSet contract.
      Specified by:
      iterator in interface Iterable<Element>
