PointDataSource

public class PointDataSource
extension PointDataSource: NativeBase
extension PointDataSource: Hashable

Point data source allows the rendering engine access to the user provided geographical locations and their attributes.

Note: This is a beta release of this feature, so there could be a few bugs and unexpected behavior. Related APIs may change for new releases without a deprecation process.

  • Called for each point, allowing inspection, removal or update of coordinates and attributes.

    Declaration

    Swift

    public typealias PointDataProcessor = (_ pointAccessor: PointDataAccessor) -> Bool

    Parameters

    pointAccessor

    the point data accessor.

    Return Value

    value indicating the result of the processing.

  • Adds a new point to the data source. Altitude of the point coordinates is ignored.

    Declaration

    Swift

    public func add(_ point: PointData)

    Parameters

    point

    Point to be added.

  • Adds new points to the data source. Altitude of the points coordinates is ignored.

    Declaration

    Swift

    public func add(_ points: [PointData])

    Parameters

    points

    Point positions.

  • Removes all points from the data source.

    Declaration

    Swift

    public func removeAll()

  • Iterates through all the points from the data source and passes them to the given processor, one by one. The processor can update the point data.

    The iteration stops after all points have been processed or the processor returns false from the process call.

    Declaration

    Swift

    public func forEach(_ processor: @escaping PointDataSource.PointDataProcessor)

    Parameters

    processor

    Point data processor.

  • Iterates through all the points from the data source and passes them to the given inspector, one by one. All points for which the inspector returns true get removed from the data source. The inspector cannot update the point data.

    Declaration

    Swift

    public func removeIf(_ processor: @escaping PointDataSource.PointDataProcessor)

    Parameters

    processor

    Point data processor.
