ee.Filter.getInfo
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
从服务器检索此对象的值。
如果未提供回调函数,则以同步方式发出请求。如果提供了回调,则会异步发出请求。
建议使用异步模式,因为同步模式在等待服务器时会停止所有其他代码(例如 EE 代码编辑器界面)。如需发出异步请求,建议使用 evaluate() 而不是 getInfo()。
返回此对象的计算值。
用法 | 返回 |

Filter.getInfo(callback) | 对象 |

此:computedobject | ComputedObject | ComputedObject 实例。 |
callback | 函数(可选) | 可选的回调。如果未提供,则以同步方式进行调用。 |
