Basic Property of Edge

Each edge shall contain two end points, start node and end node respectively. If any one node is null, this edge will be invalid. If two nodes are the same node, this edge is looped

• #from - start node
• #to - end node
• #otherNode() - another node
• #isInvalid() - whether it is invalid
• #isLooped() - whether it is looped

Looped edge

For example, creates a looped edge

var a = graph.createNode("A", -100, 0);
var edge = graph.createEdge(a, a, 'looped');
