Method containsLonLat

src/common/commontypes/Bounds.js:381–400

* @function Bounds.prototype.containsLonLat * @description 判断传入的坐标是否在范围内。 * @example * var bounds1 = new Bounds(-50,-50,40,40); * //isContains1 = true * //这里的第二个参数可以直接为 boolean 类型，也就是inclusive * var isContains1 = bounds.containsLonLat(new LonLat(40,40),true); *

(ll, options)

     * @returns {boolean} 传入坐标是否包含在范围内。
