Inherited methods

Name Inherited from Description
_collectTileGeometry(collector: TileGeometryCollector): void Protected Inherited MapLayerTileTreeReference A function that can be assigned to collectTileGeometry to enable geometry collection for references to tile trees that support geometry collection.
_createGeometryTreeReference(): undefined | GeometryTileTreeReference Protected Inherited MapLayerTileTreeReference Create a tile tree reference equivalent to this one that also supplies an implementation of collectTileGeometry.
accumulateTransformedRange(range: Range3d, matrix: Matrix4d, frustumPlanes?: FrustumPlanes): void Inherited MapLayerTileTreeReference  
addLogoCards(_cards: HTMLTableElement, _vp: ScreenViewport): void Inherited MapLayerTileTreeReference Add attribution logo cards for the tile tree source logo cards to the viewport's logo div.
addToScene(context: SceneContext): void Inherited MapLayerTileTreeReference Adds this reference's graphics to the scene.
canSupplyToolTip(hit: HitDetail): boolean Inherited MapLayerTileTreeReference Return whether this TileTreeReference can supply a tooltip describing the entity represented by the specified hit.
collectStatistics(stats: RenderMemory.Statistics): void Inherited MapLayerTileTreeReference Record graphics memory consumed by this tile tree reference.
computeTransform(tree: TileTree): Transform Protected Inherited MapLayerTileTreeReference Compute a transform from this tile tree reference's coordinate space to the IModelConnection's coordinate space.
computeWorldContentRange(): Range3d Inherited MapLayerTileTreeReference Compute the range of this tile tree's contents in world coordinates.
createDrawArgs(context: SceneContext): undefined | TileDrawArgs Inherited MapLayerTileTreeReference Create context for drawing the tile tree, if it is ready for drawing.
createGeometryTreeReference(): undefined | GeometryTileTreeReference Inherited MapLayerTileTreeReference Obtain a tile tree reference equivalent to this one that also supplies an implementation of collectTileGeometry, or
decorate(_context: DecorateContext): void Inherited MapLayerTileTreeReference Optionally add any decorations specific to this reference.
discloseTileTrees(trees: DisclosedTileTreeSet): void Inherited MapLayerTileTreeReference Disclose all TileTrees use by this reference.
draw(args: TileDrawArgs): void Inherited MapLayerTileTreeReference Adds this reference's graphics to the scene.
getAppearanceProvider(_tree: TileTree): undefined | FeatureAppearanceProvider Protected Inherited MapLayerTileTreeReference Return a provider that can supplement the view's symbology overrides.
getClipVolume(tree: TileTree): undefined | RenderClipVolume Protected Inherited MapLayerTileTreeReference Return the clip volume applied to this reference's tile tree, if any.
getHiddenLineSettings(_tree: TileTree): undefined | HiddenLine.Settings Protected Inherited MapLayerTileTreeReference Return hidden line settings to replace those defined for the view.
getLocation(): undefined | Transform Inherited MapLayerTileTreeReference Supply transform from this tile tree reference's location to iModel coordinate space.
getSymbologyOverrides(_tree: TileTree): undefined | FeatureSymbology.Overrides Protected Inherited MapLayerTileTreeReference Return overrides that replace any defined for the view.
getToolTip(hit: HitDetail): Promise<undefined | string | HTMLElement> Inherited MapLayerTileTreeReference Return a tooltip describing the hit, or undefined if no tooltip can be supplied.
getToolTipPromise(hit: HitDetail): undefined | Promise<undefined | string | HTMLElement> Inherited MapLayerTileTreeReference Obtain a tooltip describing the specified hit, or undefined if this tile tree reference cannot supply a tooltip for the hit.
getTransformFromIModel(): undefined | Transform Inherited MapLayerTileTreeReference  
getViewFlagOverrides(tree: TileTree): Partial<Mutable<NonFunctionPropertiesOf<ViewFlags>>> Protected Inherited MapLayerTileTreeReference Supply overrides that should be applied to the ViewState's ViewFlags when drawing this tile tree reference.
unionFitRange(union: Range3d): void Inherited MapLayerTileTreeReference Unions this reference's range with the supplied range to help compute a volume in world space for fitting a viewport to its contents.
createFromRenderGraphic(args: RenderGraphicTileTreeArgs): TileTreeReference Static Inherited MapLayerTileTreeReference Create a TileTreeReference that displays a pre-defined RenderGraphic.

Properties

Name Type Description
castsShadows Accessor ReadOnly boolean Return whether the geometry exposed by this tile tree reference should cast shadows on other geometry.  
imageryProvider Accessor ReadOnly undefined | MapLayerImageryProvider Returns the imagery provider for the tile tree.  
treeOwner Accessor ReadOnly TileTreeOwner Return the owner of the TileTree to draw.  

Inherited properties

Name Type Inherited from Description
_isLoadingComplete Accessor Protected Inherited ReadOnly boolean MapLayerTileTreeReference Override if additional asynchronous loading is required after the tile tree is successfully loaded, to indicate when that loading has completed.
_layerIndex Protected Inherited number MapLayerTileTreeReference  
_layerSettings Protected Inherited MapLayerSettings MapLayerTileTreeReference  
_transparency Accessor Protected Inherited ReadOnly undefined | number MapLayerTileTreeReference  
collectTileGeometry Inherited (collector: TileGeometryCollector) => void | undefined MapLayerTileTreeReference If defined, supplies the implementation of collectTileGeometry.
iModel Inherited IModelConnection MapLayerTileTreeReference  
isGlobal Accessor Inherited ReadOnly boolean MapLayerTileTreeReference Return whether this reference has global coverage. Mapping data is global and some non-primary models such as the OSM building layer have global coverage
isLoadingComplete Accessor Inherited ReadOnly boolean MapLayerTileTreeReference Return true if the tile tree is fully loaded and ready to draw.
The default implementation returns true if the tile tree loading process completed (whether it resulted in success or failure).
isOpaque Accessor Inherited ReadOnly boolean MapLayerTileTreeReference Returns true if the associated map layer, including its sublayers, is opaque.
layerIndex Accessor Inherited ReadOnly number MapLayerTileTreeReference Returns the index of the map layer associated with the tile tree.
layerName Accessor Inherited ReadOnly string MapLayerTileTreeReference  
layerSettings Accessor Inherited MapLayerSettings MapLayerTileTreeReference Returns the layer settings for the map layer.
planarClipMaskPriority Accessor Inherited ReadOnly number MapLayerTileTreeReference The PlanarClipMaskPriority of this tile tree used to determine which tile trees contribute to a clip mask when
using PlanarClipMaskMode.Priority.
transparency Accessor Inherited ReadOnly undefined | number MapLayerTileTreeReference Returns the transparency value of the map layer.
