| Edge | | public interface Edge extends Graphable(Code) | | Represents an edge in Graph. An edge is an arc in a graph which
connects exactly two nodes. These two nodes are referred to as
the A node and the B node of the edge. The order of the A node and the B node
is refered to as the node orientation of the edge.

| Method Summary | |
| public int | compareNodes(Edge other)
Compares the node orientation of the edge with another edge.
EQUAL_NODE_ORIENTATION : both nodes are equal in the correct order.UNEQUAL_NODE_ORIENTATION: both nodes are not equalOPPOSITE_NODE_ORIENTATION : both nodes are equal in opposite order. | | public Node | getNodeA()
Returns the A node of the edge. | | public Node | getNodeB()
Returns the B node of the edge. | | public Node | getOtherNode(Node node)
Returns one of the two nodes of an edge. | | public void | reverse()
Reverses the node orientation of the edge. |
| EQUAL_NODE_ORIENTATION | | final public static int EQUAL_NODE_ORIENTATION(Code) | | flag to indicate equal node orientation of two edges *
|
| OPPOSITE_NODE_ORIENTATION | | final public static int OPPOSITE_NODE_ORIENTATION(Code) | | flag to indicate opposite node orientation of two edges *
|
| UNEQUAL_NODE_ORIENTATION | | final public static int UNEQUAL_NODE_ORIENTATION(Code) | | flag to indicate unequal node orientation of two edges *
|
| compareNodes | | public int compareNodes(Edge other)(Code) | | Compares the node orientation of the edge with another edge.
EQUAL_NODE_ORIENTATION : both nodes are equal in the correct order.UNEQUAL_NODE_ORIENTATION: both nodes are not equalOPPOSITE_NODE_ORIENTATION : both nodes are equal in opposite order. |
| getNodeA | | public Node getNodeA()(Code) | | Returns the A node of the edge.
The A node. |
| getNodeB | | public Node getNodeB()(Code) | | Returns the B node of the edge.
The B node. |
| getOtherNode | | public Node getOtherNode(Node node)(Code) | | Returns one of the two nodes of an edge. If the specified node is node A,
then node B is returned, and vice versa.
Parameters:
node - The node opposite of the node to return. Node A if node B is specified, node B if node A is specified. |
| reverse | | public void reverse()(Code) | | Reverses the node orientation of the edge.
