本文整理了Java中org.geotools.feature.Feature.setAttribute()方法的一些代码示例，展示了Feature.setAttribute()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。Feature.setAttribute()方法的具体详情如下：
包路径：org.geotools.feature.Feature
类名称：Feature
方法名：setAttribute

Feature.setAttribute介绍

[英]Sets an attribute by the given zero-based index. This index is based on the values within the Feature as opposed to the AttributeType declaration. To get the values for the 5th attributeType, use the schema to determine the xPath and class the setAttribute(xPath,val) method.
[中]通过给定的从零开始的索引设置属性。此索引基于功能中的值，而不是AttributeType声明。要获取第5个attributeType的值，请使用模式确定xPath并对setAttribute（xPath，val）方法进行分类。
