/**
* @classdesc
* A vector object for geographic features with a geometry and other
* attribute properties, similar to the features in vector file formats like
* GeoJSON.
*
* Features can be styled individually with `setStyle`; otherwise they use the
* style of their vector layer.
*
* Note that attribute properties are set as {@link module:ol/Object~BaseObject} properties on
* the feature object, so they are observable, and have get/set accessors.
*
* Typically, a feature has a single geometry property. You can set the
* geometry using the `setGeometry` method and get it with `getGeometry`.
* It is possible to store more than one geometry on a feature using attribute
* properties. By default, the geometry used for rendering is identified by
* the property name `geometry`. If you want to use another geometry property
* for rendering, use the `setGeometryName` method to change the attribute
* property associated with the geometry for the feature. For example:
*
* ```js
*
* import Feature from 'ol/Feature.js';
* import Polygon from 'ol/geom/Polygon.js';
* import Point from 'ol/geom/Point.js';
*
* const feature = new Feature({
* geometry: new Polygon(polyCoords),
* labelPoint: new Point(labelCoords),
* name: 'My Polygon',
* });
*
* // get the polygon geometry
* const poly = feature.getGeometry();
*
* // Render the feature as a point using the coordinates from labelPoint
* feature.setGeometryName('labelPoint');
*
* // get the point geometry
* const point = feature.getGeometry();
* ```
*
* @api
* @template {import("./geom/Geometry.js").default} [Geometry=import("./geom/Geometry.js").default]
