      Modifier and Type Method Description
      N getNode​(int id)
      Return for a given id the node of the graph identified by it.
      int getNodeId​(N node)
      Returns for a given node of the graph an integer uniquely identifying the node.

    • Method Detail

      • getNodeId

        int getNodeId​(N node)
        Returns for a given node of the graph an integer uniquely identifying the node. The returned ids should be within the range of the number of states of the graph so that they can be used for array-based indexing.
        Parameters:
        node - the node whose id should be retrieved
        Returns:
        the (positive) id of the given graph node.
        Throws:
        IllegalArgumentException - if node does not belong to the graph.

      • getNode

        N getNode​(int id)
        Return for a given id the node of the graph identified by it.
        Parameters:
        id - the id of the node to be returned
        Returns:
        the graph node identified by the given id.
        Throws:
        IllegalArgumentException - if the given id does not identify a node of the graph.
