      Modifier and Type Method Description
      EdgeIter begin()
      The iterator pointing to the first edge.
      EdgeIter end()
      The iterator pointing to the past-the-end element.
      EdgeIter findDst​(long id, EdgeIter from)
      Construct and return the iterator pointing to the first incoming edge of the vertex with specific id after the input iterator.
      EdgeIter findSrc​(long id, EdgeIter from)
      Construct and return the iterator pointing to the first out-going edge of the vertex with specific id after the input iterator.
      default Iterator<Edge> iterator()
      Implement Iterable interface to support for-each loop.
      long size()
      Get the number of edges in the collection.
