Methods

findLink()

findLink(linkTypeId, sourceId, targetId): undefined | Link

Defined in: src/diagram/model.ts:99

Searches for any link of the specified type between elements with specified IDs in the graph if exists.

If multiple links is found, any of them could be returned.

sourceId	string
targetId	string

Returns

undefined | Link

---

getElement()

getElement(elementId): undefined | Element

Defined in: src/diagram/model.ts:82

Gets an element by its Element.id in the graph if exists.

Parameters

Parameter	Type
elementId	string

Returns

undefined | Element

---

getElementLinks()

getElementLinks(element): readonly Link[]

Defined in: src/diagram/model.ts:88

Gets all links connected to the specified element in the graph.

If element is not in the graph, no links would be returned.

If link is not in the graph, undefined would be returned instead.

Parameters

Parameter	Type
link	Link

Returns

undefined | Element

---

targetOf()

targetOf(link): undefined | Element

Defined in: src/diagram/model.ts:111
