/**
* @class BufferAnalystService
* @deprecatedclass SuperMap.BufferAnalystService
* @category iServer SpatialAnalyst BufferAnalyst
* @classdesc 缓冲区分析服务类。
* 缓冲区分析是围绕空间对象，使用与空间对象的距离值（称为缓冲半径）作为半径，生成该对象的缓冲区域的过程，
* 其中缓冲半径可以是固定数值也可以是空间对象各自的属性值。缓冲区也可以理解为空间对象的影响或服务范围。
* @param {string} url - 服务的访问地址。如：http://localhost:8090/iserver/services/spatialanalyst-changchun/restjsr/spatialanalyst。
* @param {Object} options - 参数。
* @param {boolean} [options.crossOrigin] - 是否允许跨域请求。
* @param {Object} [options.headers] - 请求头。
* @extends {SpatialAnalystBase}
* @example 例如：
* (start code)
* var myBufferAnalystService = new BufferAnalystService(url);
* (end)
* @usage
