本文整理了Java中com.vividsolutions.jts.geom.Geometry.getUserData()方法的一些代码示例，展示了Geometry.getUserData()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.getUserData()方法的具体详情如下：
包路径：com.vividsolutions.jts.geom.Geometry
类名称：Geometry
方法名：getUserData
[英]Gets the user data object for this geometry, if any.
[中]获取此几何体的用户数据对象（如果有）。

/**
* JTS 1.14 does not support intersection on a {@link GeometryCollection}. This function works around this
* by performing intersection on a flat list of geometry. The resulting list is pre-filtered for invalid
* or empty geometry (outside of bounds). Invalid geometry are logged as errors.
*
* @param envelope non-list geometry defines bounding area
* @param dataGeoms geometry pre-passed through {@link #flatFeatureList(Geometry)}
* @return list of geometry from {@code data} intersecting with {@code envelope}.
