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

Query.<init>介绍

[英]Default constructor. Use setter methods to configure the Query before use (the default Query will retrieve all features).
[中]默认构造函数。使用setter方法在使用前配置查询（默认查询将检索所有功能）。
