INTERNAL API

memberof
LayerManager

Parameters
- extLayer: IGenericSubjectMapLayer
- onlyAddIfNotExists: boolean
- appSettings: Dictionary<string>
Returns undefined | ILayerInfo

addLayer

addLayer<T>(name: string, layer: T, allowReplace?: boolean): ILayerInfo

Implementation of ILayerManager.addLayer

Adds a layer to the map

Type parameters
- T: BaseLayer<T>
Parameters
- name: string
- layer: T
- Optional allowReplace: boolean
Returns ILayerInfo
The added layer

addLayerFromParsedFeatures

addLayerFromParsedFeatures(options: IAddLayerFromParsedFeaturesOptions): Promise<ILayerInfo>

Implementation of ILayerManager.addLayerFromParsedFeatures

Adds the given parsed features as a new external layer

Parameters
- options: IAddLayerFromParsedFeaturesOptions
Returns Promise<ILayerInfo>

apply

apply(layers: ILayerInfo[]): void

Implementation of ILayerManager.apply
Parameters
- layers: ILayerInfo[]
Returns void

getLayer

getLayer<T>(name: string): undefined | T

Implementation of ILayerManager.getLayer

Gets a layer by the given name

Type parameters
- T: BaseLayer<T>
Parameters
- name: string
Returns undefined | T

getLayers

getLayers(): ILayerInfo[]

Implementation of ILayerManager.getLayers

Gets all custom layers on this map, sorted by draw order (First item is top-most layer. Last item is bottom-most layer.)

Returns ILayerInfo[]

hasLayer

hasLayer(name: string): boolean

Implementation of ILayerManager.hasLayer

Gets whether the specified custom layer exists on the map

Parameters
- name: string
Returns boolean

parseFeaturesFromFile

parseFeaturesFromFile(options: IParseFeaturesFromFileOptions): Promise<IParsedFeatures>

Implementation of ILayerManager.parseFeaturesFromFile

Attempts to parse features for the given input file. A failed attempt is when calling hasFeatures() on the returned parsed features returns false.

Parameters
- options: IParseFeaturesFromFileOptions
Returns Promise<IParsedFeatures>

removeLayer

removeLayer(name: string): undefined | BaseLayer

Implementation of ILayerManager.removeLayer

Removes a layer by the given name

Parameters
- name: string
Returns undefined | BaseLayer

tryGetSubjectLayer

tryGetSubjectLayer(): undefined | BaseLayer

Implementation of ILayerManager.tryGetSubjectLayer

Get the active subject layer if present on the current map. In a MapGuide-specific context, subject layers do not exist and this method will always return undefined in such cases

Returns undefined | BaseLayer
