MapFeatureQueryDelegate

Definition of the feature query delegate. Provide interface to query map's features.

Functions

abstract fun executeOnRenderThread(runnable: Runnable)

In some cases querying source / render features is expected to be a blocking operation e.g. performing this action on map click. In this case in order to avoid deadlock on main thread querying could be performed on render thread and in that case querying result will be also delivered on render thread not leading to the main thread deadlock. Example:

queryRenderedFeatures

abstract fun queryRenderedFeatures(geometry: RenderedQueryGeometry, options: RenderedQueryOptions, callback: QueryRenderedFeaturesCallback): Cancelable

Queries the map for rendered features.

querySourceFeatures

abstract fun querySourceFeatures(sourceId: String, options: SourceQueryOptions, callback: QuerySourceFeaturesCallback): Cancelable

Queries the map for source features.
