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

Query.setProperties介绍

[英]Set the names of the properties that this Query should retrieve as part of the returned org.geotools.feature.FeatureCollection. As well as an array of names, the following constants can be used:

  • #ALL_PROPERTIES to retrieve all properties.
  • #NO_PROPERTIES to indicate no properties are required, just feature IDs.
    The available properties can be determined with FeatureSource#getSchema(). If properties that are not part of the source's schema are requested an exception will be thrown.
    [中]设置此查询应作为返回组织的一部分检索的属性的名称。地理工具。特色特色系列。除了名称数组之外，还可以使用以下常量：
    *#ALL_PROPERTIES以检索所有属性。
    *#NO_属性表示不需要属性，只需要功能ID。
    可用属性可通过FeatureSource#getSchema（）确定。如果请求不属于源架构的属性，则会引发异常。
