    Properties

    attributes: Readonly<Record<string | symbol, unknown>>

    Additional attributes associated with this layer.

    children: undefined | ChildrenCollection<AnyLayer>

    The direct children of this layer.

    The children may either be a set of operational layers (e.g. for a group layer) or a set of sublayers, or undefined.

    See also layers and sublayers.

    description: string

    The human-readable description of this layer. May be empty.

    id: string

    The unique id of this layer within its map model.

    NOTE: layer ids may not be globally unique: layers that belong to different map models may have the same id.

    isBaseLayer: boolean

    True if this layer is a base layer.

    Only one base layer can be visible at a time.

    layers: undefined

    If this layer is a group layer this property contains a collection of all layers that a members to the group.

    The property shall be undefined if it is not a group layer.

    The properties layers and sublayers are mutually exclusive.

    legend: undefined | string

    Legend URL from the service capabilities, if available.

    Note: this property may be expanded upon in the future, e.g. to support more variants than just image URLs.

    loadState: LayerLoadState

    The load state of a layer.

    map: MapModel

    The map this layer belongs to.

    olLayer: BaseLayer

    The raw OpenLayers layer.

    parent: undefined | AnyLayer

    The direct parent of this layer instance, used for sublayers or for layers in a group layer.

    The property shall be undefined if the layer is not a sublayer or member of a group layer.

    sublayers: SublayersCollection<WMSSublayer>

    The collection of child sublayers for this layer. Sublayers are layers that cannot exist without an appropriate parent layer.

    Layers that can never have any sublayers may not have a sublayers collection.

    The properties layers and sublayers are mutually exclusive.

    title: string

    The human-readable title of this layer.

    type: "wms"

    Identifies the type of this layer.

    url: string

    The URL of the WMS service that was used during layer construction.

    visible: boolean

    Whether the layer is visible or not.

    NOTE: The model's visible state may do more than influence the raw OpenLayers's visibility property. Future versions may completely remove invisible layers from the OpenLayer's map under some circumstances.

    Methods

    • Updates the attributes of this layer. Values in newAttributes are merged into the existing ones (i.e. via Object.assign).

      Parameters

      • newAttributes: Record<string | symbol, unknown>

      Returns void
