 * @class mapboxgl.Zondy.Map.MapVectorLayer
 * @classdesc mapboxgl瓦片地图加载类
 * @param gdbps - {String} 必选。图层的gdbps地址,允许多个图层,以","隔开
 * @param option - {Object} 属性键值对,地图属性字段。
 * @param {String} [option.domain = ''] 【domain和(networkProtocol,ip,port)二选一】。域名
 * @param {String} [option.networkProtocol = location.protocol.split(":")[0] || "http"] 【domain和(networkProtocol,ip,port)二选一】。网络协议
 * @param {String} [option.ip = localhost] 【domain和(networkProtocol,ip,port)二选一】。地图服务ip
 * @param {String} [option.port = 6163] 【domain和(networkProtocol,ip,port)二选一】。地图服务端口
 *
 * @param {String} [option.filters = null] 可选。用户指定的图层过滤条件,它由多个键值对组成,值为过滤条件。例:filters=1:ID>4,3:ID>1
 * @param {String} [option.style = null] 可选。用户指定的图层显示样式,每个gdbp对应一个style,style为CDisplayStyleExtend的json序列化形式,多个style之间用","隔开。例:sytles=[{index:0,symbleshow:true,followscale:true},{index:1,symbleshow:true,FollowScale:true}]
 * @param {String} [option.f = null] 可选。矢量图片的格式。jpg|png|gif(默认)
 * @param {String} [option.tileSize = 512] 可选。瓦片大小
 * @param {String} [option.layerID] 可选。
 * @param {String} [option.sourceID] 可选。
