方法名：setCoordinateSystem

Query.setCoordinateSystem介绍

[英]Provide an override coordinate system to apply to features retrieved by this Query.

This denotes a request to temporarily override the coordinate system contained in the feature data source being queried. The same coordinate values will be used, but the features retrieved will appear in this Coordinate System.

This change is not persistent and only applies to the features returned by this Query. If used in conjunction with #getCoordinateSystemReproject() the reprojection will occur from #getCoordinateSystem() to #getCoordinateSystemReproject().
[中]提供替代坐标系以应用于此查询检索的要素。
这表示请求临时替代所查询要素数据源中包含的坐标系。将使用相同的坐标值，但检索到的特征将显示在此坐标系中。
此更改不是持久性的，仅适用于此查询返回的功能。如果与#getCoordinateSystemReproject（）一起使用，则重新投影将从#getCoordinateSystem（）到#getCoordinateSystemReproject（）。
