Methods

  • This method must be overwritten by any implementations. Before returning the array of features, be sure to use the getProviderFeature on each feature to ensure all properties and symbols required by the VCM architecture to handle your feature is called: (e.g. return features.map(f => this.getProviderFeature(f));

    Parameters

    • _coordinate: Coordinate
    • _resolution: number
    • Optional_headers: Record<string, string>

    Returns Promise<Feature<Geometry>[]>

  • Ensures the feature has an ID, applies all vectorProperties and adds style and the vcsLayerName and isProvidedFeature symbols to the feature

    • feature: Feature<Geometry>

    Returns Feature<Geometry>
