MapFeatureQueryDelegate

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

Functions

equals

open operator override fun equals(other: Any?): Boolean

executeOnRenderThread

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:

fun onMapClick() { executeOnRenderThread { queryRenderedFeatures(pixel, options) { // result callback called, do needed actions lock.notify() } } lock.wait() return false }

abstract fun executeOnRenderThread(runnable: Runnable)

hashCode

open override fun hashCode(): Int

queryRenderedFeatures

Queries the map for rendered features.

abstract fun queryRenderedFeatures(box: ScreenBox, options: RenderedQueryOptions, callback: QueryFeaturesCallback)

abstract fun queryRenderedFeatures(pixel: ScreenCoordinate, options: RenderedQueryOptions, callback: QueryFeaturesCallback)

abstract fun queryRenderedFeatures(shape: List<ScreenCoordinate?>, options: RenderedQueryOptions, callback: QueryFeaturesCallback)

querySourceFeatures

Queries the map for source features.

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

toString

open override fun toString(): String
