Properties

Property	Optional	Description	Type	Default
id	No	Node Identifier	string
dependencies	Yes	List of ID list which represents the node depends on	string[]

API (IViewNode)

After the DAG initialization, all Node objects given by the uses are wrapped with a set of API that can control node behavior. The wrap object is called IViewNode.

Name	Description	Type
shrink	Hide child nodes	()=>void
expand	Show all child nodes	()=>void
remove	Remove the node	()=>void
withChildren	Call the method can change the children of the node	(promise: Promise<Node[]>, useCache?: boolean) => void
joint	Indicator which shows the node is a joint node	boolean
setPoint	Set node position	(point: Point) => void
connect	Create an Edge with the given node	(node: IViewNode) => void
addChildNode	Add a child node	(node: Node, point: Point) => void
