本文整理了Java中com.google.gdata.client.Query类的一些代码示例，展示了Query类的具体用法。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类的具体详情如下：
包路径：com.google.gdata.client.Query
类名称：Query

Query介绍

[英]The Query class is a helper class that aids in the construction of a GData query. It provides a simple API and object model that exposes query parameters. Once constructed, the query can be executed against a GData service.

The Query class also acts as a simple base class for GData services that support custom query parameters. These services can subclass the base Query class, add APIs to represent service query parameters, and participate in the Query URI generation process.
[中]查询类是一个帮助器类，帮助构造GData查询。它提供了一个简单的API和对象模型来公开查询参数。一旦构造好，就可以对GData服务执行查询。
查询类还充当支持自定义查询参数的GData服务的简单基类。这些服务可以对基本查询类进行子类化，添加API来表示服务查询参数，并参与查询URI生成过程。
