Class AlgorithmObjectExtractor.Edge

  • Enclosing class:
    AlgorithmObjectExtractor

    protected class AlgorithmObjectExtractor.Edge
    extends java.lang.Object
    A representation of an edge for the vertex-edge-triangle table. This class stores the pair of vertex indices for the end points of the edge. The edges and are considered to be identical. To simplify comparisons, the class stores the ordered indices. The class extends Object to obtain support for hashing into a map of edges.

      • Edge

        public Edge​(int i0,
                    int i1)
        Constructs an edge in the table.
        Parameters:
        i0 - a vertex index for an end point
        i1 - a vertex index for an end point

      • equals

        public boolean equals​(java.lang.Object kObject)
        Support for hashing into a map of edges.
        Overrides:
        equals in class java.lang.Object
        Parameters:
        kObject - an edge for comparison to the current one
        Returns:
        true iff the edges are identical. Because the class stores ordered indices, it is not necessary to use the more expensive test (i0 == other.i0 && i1 == other.i1) || (i0 == other.i1 && i1 == other.i0).
      • hashCode

        public int hashCode()
        Support for hashing into a map of edges.
        Overrides:
        hashCode in class java.lang.Object
        Returns:
        the hash key for the edge
