Geometry.equals介绍

[英]Tests whether this geometry is structurally and numerically equal to a given Object. If the argument Object is not a Geometry, the result is false. Otherwise, the result is computed using #equalsExact(Geometry).

This method is provided to fulfill the Java contract for value-based object equality. In conjunction with #hashCode() it provides semantics which are most useful for using Geometrys as keys and values in Java collections.

Note that to produce the expected result the input geometries should be in normal form. It is the caller's responsibility to perform this where required (using Geometry#norm()or #normalize() as appropriate).
[中]测试此几何体在结构和数值上是否等于给定的Object。如果参数Object不是Geometry，则结果为false。否则，使用#equalsExact（几何体）计算结果。
提供此方法是为了实现基于值的对象相等的Java契约。它与#hashCode（）结合使用，提供了在Java集合中将Geometry用作键和值时最有用的语义。
请注意，要产生预期结果，输入几何图形应为标准形式。调用方有责任在需要时执行此操作（根据需要使用Geometry#norm（）或#normalize（））。
