 */
/**
 * @typedef {Object} Options
 * @property {import("../events/condition.js").Condition} [addCondition] A function
 * that takes a {@link module:ol/MapBrowserEvent~MapBrowserEvent} and returns a
 * boolean to indicate whether that event should be handled.
 * By default, this is {@link module:ol/events/condition.never}. Use this if you
 * want to use different events for add and remove instead of `toggle`.
 * @property {import("../events/condition.js").Condition} [condition] A function that
 * takes a {@link module:ol/MapBrowserEvent~MapBrowserEvent} and returns a
 * boolean to indicate whether that event should be handled. This is the event
 * for the selected features as a whole. By default, this is
 * {@link module:ol/events/condition.singleClick}. Clicking on a feature selects that
 * feature and removes any that were in the selection. Clicking outside any
 * feature removes all from the selection.
 * See `toggle`, `add`, `remove` options for adding/removing extra features to/
 * from the selection.
 * @property {Array<import("../layer/Layer.js").default>|function(import("../layer/Layer.js").default<import("../source/Source").default>): boolean} [layers]
 * A list of layers from which features should be selected. Alternatively, a
 * filter function can be provided. The function will be called for each layer
 * in the map and should return `true` for layers that you want to be
 * selectable. If the option is absent, all visible layers will be considered
 * selectable.
 * @property {import("../style/Style.js").StyleLike|null} [style]
 * Style for the selected features. By default the default edit style is used
 * (see {@link module:ol/style/Style~Style}). Set to `null` if this interaction should not apply
 * any style changes for selected features.
 * If set to a falsey value, the selected feature's style will not change.
 * @property {import("../events/condition.js").Condition} [removeCondition] A function
 * that takes a {@link module:ol/MapBrowserEvent~MapBrowserEvent} and returns a
 * boolean to indicate whether that event should be handled.
 * By default, this is {@link module:ol/events/condition.never}. Use this if you
 * want to use different events for add and remove instead of `toggle`.
 * @property {import("../events/condition.js").Condition} [toggleCondition] A function
 * that takes a {@link module:ol/MapBrowserEvent~MapBrowserEvent} and returns a
 * boolean to indicate whether that event should be handled. This is in addition
 * to the `condition` event. By default,
 * {@link module:ol/events/condition.shiftKeyOnly}, i.e. pressing `shift` as
 * well as the `condition` event, adds that feature to the current selection if
 * it is not currently selected, and removes it if it is. See `add` and `remove`
 * if you want to use different events instead of a toggle.
 * @property {boolean} [multi=false] A boolean that determines if the default
 * behaviour should select only single features or all (overlapping) features at
 * the clicked map position. The default of `false` means single select.
 * @property {Collection<Feature>} [features]
 * Collection where the interaction will place selected features. Optional. If
 * not set the interaction will create a collection. In any case the collection
 * used by the interaction is returned by
 * {@link module:ol/interaction/Select~Select#getFeatures}.
 * @property {FilterFunction} [filter] A function
 * that takes a {@link module:ol/Feature~Feature} and a
 * {@link module:ol/layer/Layer~Layer} and returns `true` if the feature may be
 * selected or `false` otherwise.
 * @property {number} [hitTolerance=0] Hit-detection tolerance. Pixels inside
 * the radius around the given position will be checked for features.
