Accessors

cellsVersion

Get Signature

get cellsVersion(): number

Defined in: src/diagram/model.ts:70

Graph content (elements and links) version number which changes on every cell change (when element or link added/removed/reordered, see DiagramModelEvents.changeCells).

Returns

number

Inherited from

GraphStructure.cellsVersion

---

elements

Get Signature

get elements(): readonly Element[]

Defined in: src/diagram/model.ts:74

All elements (nodes) in the graph.

Returns

readonly Element[]

Inherited from

GraphStructure.elements

---

factory

Get Signature

get factory(): DataFactory

Defined in: src/diagram/model.ts:65

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

Returns

DataFactory

Inherited from

GraphStructure.factory

---

links

Get Signature

get links(): readonly Link[]

Defined in: src/diagram/model.ts:78

All links (edges) between elements in the graph.

Returns

readonly Link[]

Inherited from

GraphStructure.links

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.

Parameters

Parameter	Type
linkTypeId	LinkTypeIri
sourceId	string
targetId	string

Returns

undefined | Link

Inherited from

GraphStructure.findLink

---

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

Inherited from

GraphStructure.getElement

---

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.

Parameters

Parameter	Type
element	Element

Returns

readonly Link[]

Inherited from

GraphStructure.getElementLinks

---

getElementType()

getElementType(elementTypeIri): undefined | ElementType

Defined in: src/editor/dataDiagramModel.ts:118

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

---

getLink()

getLink(linkId): undefined | Link

Defined in: src/diagram/model.ts:92

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

Parameters

Parameter	Type
linkId	string

Returns

undefined | Link

Inherited from

GraphStructure.getLink

---

getLinkType()

getLinkType(linkTypeIri): undefined | LinkType

Defined in: src/editor/dataDiagramModel.ts:127

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

---

getLinkVisibility()

getLinkVisibility(linkTypeId): LinkTypeVisibility

Defined in: src/diagram/model.ts:115

Gets current visibility mode for the specified link type.

Parameters

Parameter	Type
linkTypeId	LinkTypeIri

Returns

LinkTypeVisibility

Inherited from

GraphStructure.getLinkVisibility

---

getPropertyType()

getPropertyType(propertyTypeIri): undefined | PropertyType

Defined in: src/editor/dataDiagramModel.ts:137

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

---

sourceOf()

sourceOf(link): undefined | Element

Defined in: src/diagram/model.ts:105

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

---

targetOf()

targetOf(link): undefined | Element

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

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
