Method Details
-
getNodeA
Description copied from interface:Edge
Returns the A node of the edge. -
getNodeB
Description copied from interface:Edge
Returns the B node of the edge. -
getOtherNode
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.

reverse
public void reverse()Description copied from interface:Edge
Reverses the node orientation of the edge. -
compareNodes
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.

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.
