Class Feature<TShape, TProperties>

Type parameters

• TShape: Shape | null

  Represents the type of feature's shape. Default type is inferred from the 'shape' passed to the constructor.

• TProperties: FeatureProperties

  Represents the type of feature's properties. Default type is inferred from the 'properties' passed to the constructor. If the 'properties' is not provided the type is defaulted to FeatureProperties.

    // Creates a type-guarded Feature with the Point shape and specific properties
    const leuvenCity = new Feature(point, {name: 'Leuven'});
    // TypeScript infers the shape and properties type from the constructor inputs
    const {x, y} = leuvenCity.shape;
    console.log(`city: ${leuvenCity.properties.name}`);
  
    // Let TypeScript know the types explicitly
    interface CityProps {name: string, population: number}
    const anotherCity = new Feature<Point, CityProps>(point, {name: 'Brussels', population: 2_100_000});
    anotherCity.properties.population += 20_000;
