Class Cycle

    • Method Detail

      • isValid

        public boolean isValid()
        Tests if the cycle is valid. A valid cycle satisfies two conditions:

        1. Each pair of adjacent nodes share an edge.
        2. The first and last nodes share an edge. 3. The only node repetition is the first and last nodes.
        Specified by:
        isValid in interface NodeSequence
        Overrides:
        isValid in class Walk
        Returns:
        True if valid, otherwise false.
      • buildEdges

        protected List<Edge> buildEdges()
        Description copied from class: Walk
        Internal method for building the edge set of the walk. This method calculated the edges upon every call.
        Overrides:
        buildEdges in class Walk
        Returns:
        The list of edges for the walk, or null if the edge set could not be calculated due to an invalid walk.
