Accessors

elements

get elements(): readonly Element[]

All elements (nodes) in the graph.

Returns

readonly Element[]

Inherited from

GraphStructure.elements

Defined in

diagram/model.ts:69

---

factory

get factory(): DataFactory

Provides an RDF term factory to create RDF terms for identifiers and property values.

Returns

DataFactory

Inherited from

GraphStructure.factory

Defined in

diagram/model.ts:65

---

links

get links(): readonly Link[]

All links (edges) between elements in the graph.

Returns

readonly Link[]

Inherited from

GraphStructure.links

Defined in

diagram/model.ts:73

Methods

findLink()

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

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.

Parameters

Parameter	Type
linkTypeId	LinkTypeIri
sourceId	string
targetId	string

Returns

undefined | Link

Inherited from

GraphStructure.findLink

Defined in

diagram/model.ts:94

---

getElement()

getElement(elementId): undefined | Element

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

Parameters

Parameter	Type
elementId	string

Returns

undefined | Element

Inherited from

GraphStructure.getElement

Defined in

diagram/model.ts:77

---

getElementLinks()

getElementLinks(element): readonly Link[]

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

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

Parameters

Parameter	Type
element	Element

Returns

readonly Link[]

Inherited from

GraphStructure.getElementLinks

Defined in

diagram/model.ts:83

---

getElementType()

getElementType(elementTypeIri): undefined | ElementType

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

Element types are added to the graph as requested by DataDiagramModel.createElementType so the data (e.g. labels) can be fetched from a data provider.

Parameters

Parameter	Type
elementTypeIri	ElementTypeIri

Returns

undefined | ElementType

See

DataDiagramModel.createElementType

Defined in

editor/dataDiagramModel.ts:115

---

getLink()

getLink(linkId): undefined | Link

Gets a link by its Link.id in the graph if exists.

Parameters

Parameter	Type
linkId	string

Returns

undefined | Link

Inherited from

GraphStructure.getLink

Defined in

diagram/model.ts:87

---

getLinkType()

getLinkType(linkTypeIri): undefined | LinkType

Gets an link type by its LinkType.id in the graph if exists.

Link types are added to the graph as requested by DataDiagramModel.createLinkType so the data (e.g. labels) can be fetched from a data provider.

Parameters

Parameter	Type
linkTypeIri	LinkTypeIri

Returns

undefined | LinkType

See

DataDiagramModel.createLinkType

Defined in

editor/dataDiagramModel.ts:124

---

getLinkVisibility()

getLinkVisibility(linkTypeId): LinkTypeVisibility

Gets current visibility mode for the specified link type.

Parameters

Parameter	Type
linkTypeId	LinkTypeIri

Returns

LinkTypeVisibility

Inherited from

GraphStructure.getLinkVisibility

Defined in

diagram/model.ts:110

---

getPropertyType()

getPropertyType(propertyTypeIri): undefined | PropertyType

Gets an property type by its PropertyType.id in the graph if exists.

Property types are added to the graph as requested by DataDiagramModel.createPropertyType so the data (e.g. labels) can be fetched from a data provider.

Parameters

Parameter	Type
propertyTypeIri	PropertyTypeIri

Returns

undefined | PropertyType

See

DataDiagramModel.createPropertyType

Defined in

editor/dataDiagramModel.ts:134

---

sourceOf()

sourceOf(link): undefined | Element

Gets a source element for the specified link in the graph.

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

Parameters

Parameter	Type
link	Link

Returns

undefined | Element

Inherited from

GraphStructure.sourceOf

Defined in

diagram/model.ts:100

---

targetOf()

targetOf(link): undefined | Element

Gets a target element for the specified link in the graph.

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

Parameters

Parameter	Type
link	Link

Returns

undefined | Element

Inherited from

GraphStructure.targetOf

Defined in

diagram/model.ts:106
