getNodeA
public Node getNodeA()
Description copied from interface:Edge
Returns the A node of the edge.- Specified by:
getNodeA
in interfaceEdge
- Returns:
- The A node.
- See Also:
Edge.getNodeA()
-
getNodeB
public Node getNodeB()
Description copied from interface:Edge
Returns the B node of the edge.- Specified by:
getNodeB
in interfaceEdge
- Returns:
- The B node.
- See Also:
Edge.getNodeB()
-
getOtherNode
public Node getOtherNode(Node node)
Description copied from interface:Edge
Returns one of the two nodes of an edge. If the specified node is node A, then node B is returned, and vice versa.- Specified by:
getOtherNode
in interfaceEdge
- Parameters:
node
- The node opposite of the node to return.- Returns:
- Node A if node B is specified, node B if node A is specified.
- See Also:
Edge.getOtherNode(Node)
-
reverse
public void reverse()
Description copied from interface:Edge
Reverses the node orientation of the edge.- Specified by:
reverse
in interfaceEdge
- See Also:
Edge.reverse()
-
compareNodes
public int compareNodes(Edge other)
Description copied from interface:Edge
Compares the node orientation of the edge with another edge.- Specified by:
compareNodes
in interfaceEdge
- Returns:
- EQUAL_NODE_ORIENTATION : both nodes are equal in the correct order. UNEQUAL_NODE_ORIENTATION: both nodes are not equal OPPOSITE_NODE_ORIENTATION : both nodes are equal in opposite order.
- See Also:
Edge.compareNodes(Edge)
-
getRelated
public Iterator<Edge> getRelated()
Description copied from interface:Graphable
Returns an iterator over any related components. A graph component is related to other components of the graph of similary type through some relationship.- Specified by:
getRelated
in interfaceGraphable
- Returns:
- Iterator An iterator over other components of the graph that are related to the component.
