包路径：org.apache.sis.util.Utilities
类名称：Utilities
方法名：equalsIgnoreMetadata

Utilities.equalsIgnoreMetadata介绍

[英]Compares the specified objects for equality, ignoring metadata. If this method returns true, then:

  • If the two given objects are org.apache.sis.referencing.operation.transform.AbstractMathTransform, then transforming a set of coordinate values using one transform will produce the same results than transforming the same coordinates with the other transform.
  • If the two given objects are org.apache.sis.referencing.crs.AbstractCRS (CRS), then a call to org.apache.sis.referencing.CRS#findOperation(crs1, crs2, null) will return an identity operation.
    If a more lenient comparison allowing slight differences in numerical values is wanted, then #equalsApproximatively(Object,Object) can be used instead.

Implementation note
This is a convenience method for the following method call: java
[中]比较指定对象的相等性，忽略元数据。如果此方法返回true，则：
*如果给定的两个对象是org。阿帕奇。姐妹。参考。活动使改变AbstractMathTransform，然后使用一个变换变换一组坐标值，将产生与使用另一个变换变换相同坐标值相同的结果。
*如果给定的两个对象是org。阿帕奇。姐妹。参考。crs。AbstractCRS（CRS），则对org.apache.sis.referencing.CRS#findOperation(crs1, crs2, null)的调用将返回标识操作。
如果需要更宽松的比较，允许数值略有差异，那么可以使用#等近似（Object，Object）。
实施说明
这是以下方法调用的一个方便方法：java
