addGeoJSONSourceFeatures

Add additional features to a GeoJSON style source. The data will be scheduled and applied on a worker thread.

To check the result of the operation, use events API, which will propagate a map-loaded event upon success or a map-loading-error event upon failure.

Partially updating a GeoJSON source is not compatible with using shared cache and generated IDs. It is important to ensure that every feature in the GeoJSON style source, as well as the newly added feature, has a unique ID (or a unique promote ID if in use). Failure to provide unique IDs will result in a map-loading-error.

The method allows the user to provide a data ID, which will be returned as the dataId parameter in the source-data-loaded event. However, it's important to note that multiple partial updates can be queued for the same GeoJSON source when ongoing source parsing is taking place. In these cases, the partial updates will be applied to the source in batches. Only the data ID provided in the most recent call within each batch will be included in the source-data-loaded event. If no data ID is provided in the most recent call, the data ID in the source-data-loadedevent will be null.

Note: This method is not thread-safe. The List will be processed on a worker thread, please make sure the underlying features are immutable.

Note: calling GeoJsonSource.geometry, GeoJsonSource.feature, GeoJsonSource.featureCollection, GeoJsonSource.data, GeoJsonSource.url will clear any pending GeoJSON source data operations if they were scheduled before.
