Graphic Set Membership

Graphic object supports the set membership. Child may be added or deleted. Or parent node can be modified. The graphics can form a relation of tree-form graph in GraphModel.

• #children - child collection
• #parent - parent node
• #addChild - add child
• #clearChildren - clear child node
• #forEachChild - traverse child node
• #getChildAt - get child node
• #getChildIndex - get child order number

Example

Set up the set membership of nodes

var node = graph.createNode();
var child = graph.createNode("child");
child.parent = node;
//or use#addChild(...)
//node.addChild(child);
