    • Constructor Detail

      • AbstractTypedGraph

        public AbstractTypedGraph​(EdgeType edge_type)
        Creates an instance with the specified edge type.
        Parameters:
        edge_type - the type of edges that this graph accepts
    • Method Detail

      • getDefaultEdgeType

        public EdgeType getDefaultEdgeType()
        Returns this graph's edge type.
        Returns:
        the default edge type for this graph
      • getEdgeType

        public EdgeType getEdgeType​(E e)
        Returns this graph's edge type, or null if e is not in this graph.
        Parameters:
        e - the edge whose type is to be returned
        Returns:
        the EdgeType of edge, or null if edge has no defined type
      • getEdges

        public java.util.Collection<E> getEdges​(EdgeType edge_type)
        Returns the edge set for this graph if edgeType matches the edge type for this graph, and an empty set otherwise.
        Parameters:
        edge_type - the type of edges to be returned
        Returns:
        the collection of edges which are of type edge_type, or null if the graph does not accept edges of this type

        protected boolean hasEqualEdgeType​(EdgeType edge_type)
        Parameters:
        edge_type - the edge type to compare to this instance's default edge type
        Returns:
        true if edge_type matches the default edge type for this graph, and false otherwise
      • validateEdgeType

        protected void validateEdgeType​(EdgeType edge_type)
        Throws an IllegalArgumentException if edge_type does not match the default edge type for this graph.
        Parameters:
        edge_type - the edge type to compare to this instance's default edge type
