本文整理了Java中com.esri.core.geometry.Geometry.isEmpty()方法的一些代码示例，展示了Geometry.isEmpty()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Geometry.isEmpty()方法的具体详情如下：
包路径：com.esri.core.geometry.Geometry
类名称：Geometry
方法名：isEmpty

Geometry.isEmpty介绍

[英]IsEmpty returns TRUE when the Geometry object does not contain geometric information beyond its original initialization state.
[中]当几何体对象不包含超出其原始初始化状态的几何信息时，IsEmpty返回TRUE。
