PointOfInterestManaging

public protocol PointOfInterestManaging : AnyObject

Properties

  • Declaration

    Swift

    var delegate: PointOfInterestManagerDelegate? { get set }

  • Indicates whether user interaction for selection is enabled.

    When set to true, the user can interact with the POIs to select them. When set to false, selection is disabled and user interaction will not result in any selection changes.

    The default value is true.

    Declaration

    Swift

    var isUserSelectionEnabled: Bool { get set }

  • Determines how POIs can be selected. See PointOfInterestManager.SelectionMode for possible values.

    When changing from .multiple to .single, all previously selected POIs, except one, will be unselected.

    Default value is .single.

    Swift

    var selectionMode: PointOfInterestManager.SelectionMode { get set }

Selection

  • Retrieves the set of currently selected POIs (for .multiple mode).

    Return Value

    A Set of currently selected PointOfInterest. May be empty.

    This method should be used only when selectionMode is set to .single. Otherwise, it will return the first selected POI. If selectionMode is set to .multiple use getSelectedPOIs.

    Declaration

    Swift

    func getSelectedPOI() -> PointOfInterest?

    Return Value

    The currently selected PointOfInterest, or nil if none is selected.

  • Unselects all selected POIs (for .multiple mode).

Filtering

  • Filters POIs based on the presence of a specific tag.

    Parameters

    tag

    The tag to filter by.

Sorting

  • Sorts POIs by graph distance from a given origin.

    This function utilizes a graph-based routing to calculate the distance from the origin to each POI. The POIs are then sorted in ascending order of distance.

    Declaration

    Swift

    func sortPOIsByGraphDistance(origin: Coordinate, pois: [PointOfInterest]) -> Single<[PointOfInterestWithInfo]>

    Parameters

    origin

    The origin Coordinate for distance calculation.
    pois

    An array of POIs to sort.

    Return Value

    A Single emitting an array of PointOfInterestWithInfo sorted by graph distance. The PointOfInterestWithInfo objects contain the original POI data and additional information including the calculated distance. If a POI’s distance cannot be determined, it will likely be placed at the end of the sorted array, or an error will be propagated through the Single.

  • Sorts POIs by estimated travel duration from a given origin.

    This function takes an origin coordinate and an array of POIs and returns a Single emitting an array of POIs sorted by the time it takes to travel from the origin to each POI. The returned array contains PointOfInterestWithInfo objects which encapsulate the original POI and associated travel information.

    Declaration

    Swift

    func sortPOIsByDuration(origin: Coordinate, pois: [PointOfInterest]) -> Single<[PointOfInterestWithInfo]>

    Parameters

    origin

    The origin Coordinate.
    pois

    An array of POIs to sort.

    Return Value

    A Single emitting an array of PointOfInterestWithInfo sorted by duration. The array will be sorted in ascending order of duration (shortest duration first). If the origin is the same as a POI, the duration will be 0. If a POI’s duration cannot be determined, it will likely be placed at the end of the sorted array, or an error will be propagated through the Single.

  • Sorts all POIs by graph distance from a given origin.

    This function utilizes a graph-based routing to calculate the distance from the origin to each POI. The POIs are then sorted in ascending order of distance.

    Declaration

    Swift

    func sortPOIsByGraphDistance(origin: Coordinate) -> Single<[PointOfInterestWithInfo]>

    Parameters

    origin

    The origin Coordinate for distance calculation.

    Return Value

    A Single emitting an array of PointOfInterestWithInfo sorted by graph distance. The PointOfInterestWithInfo objects contain the original POI data and additional information including the calculated distance. If a POI’s distance cannot be determined, it will likely be placed at the end of the sorted array, or an error will be propagated through the Single.

  • Sorts all POIs by estimated travel duration from a given origin.

    This function takes an origin coordinate and an array of all POIs and returns a Single emitting an array of POIs sorted by the time it takes to travel from the origin to each POI. The returned array contains PointOfInterestWithInfo objects which encapsulate the original POI and associated travel information.

    Declaration

    Swift

    func sortPOIsByDuration(origin: Coordinate) -> Single<[PointOfInterestWithInfo]>

    Parameters

    origin

    The origin Coordinate.

    Return Value

    A Single emitting an array of PointOfInterestWithInfo sorted by duration. The array will be sorted in ascending order of duration (shortest duration first). If the origin is the same as a POI, the duration will be 0. If a POI’s duration cannot be determined, it will likely be placed at the end of the sorted array, or an error will be propagated through the Single.
