包路径：org.geotools.referencing.CRS
类名称：CRS
方法名：getEnvelope

CRS.getEnvelope介绍

[英]Returns the domain of validity for the specified coordinate reference system, or nullif unknown.

This method fetchs the CoordinateReferenceSystem#getDomainOfValidity associated with the given CRS. Only GeographicExtent of kind BoundingPolygon are taken in account. If none are found, then the #getGeographicBoundingBox are used as a fallback.

The returned envelope is expressed in terms of the specified CRS.
[中]返回指定坐标参照系的有效域，如果未知，则返回null。
此方法获取与给定CRS关联的CoordinationReferenceSystem#getDomainOfValidity。只考虑边界多边形的地理范围。如果没有找到，则将#getGeographicBoundingBox用作回退。
返回的信封用指定的CRS表示。
