类名称：Geometry
方法名：equalsExact

Geometry.equalsExact介绍

[英]Returns true if the two Geometrys are exactly equal. Two Geometries are exactly equal iff:

  • they have the same structure
  • they have the same values for their vertices, in exactly the same order.
    This provides a stricter test of equality than #equalsTopo(Geometry), which is more useful in certain situations (such as using geometries as keys in collections).

This method does not test the values of the GeometryFactory, the SRID, or the userData fields.

To properly test equality between different geometries, it is usually necessary to #normalize() them first.
[中]如果两个Geometry完全相等，则返回true。两个几何体完全相等：
*它们具有相同的结构
*它们的顶点具有相同的值，顺序完全相同。
这提供了比#equalsTopo（几何体）更严格的相等性测试，它在某些情况下更有用（例如将几何体用作集合中的键）。
此方法不测试GeometryFactory、SRID或userData字段的值。
为了正确测试不同几何体之间的相等性，通常需要首先对它们进行#规格化（）。
