本文整理了Java中org.infinispan.query.dsl.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：org.infinispan.query.dsl.Query
类名称：Query

Query介绍

[英]An immutable object representing both the query and the result. The result is obtained lazily when one of the methods in this interface is executed first time. The query is executed only once. Further calls will just return the previously cached results. If you intend to re-execute the query to obtain fresh data you need to build another instance using a QueryBuilder.
[中]表示查询和结果的不可变对象。当第一次执行此接口中的一个方法时，将延迟获得结果。查询只执行一次。进一步的调用只会返回以前缓存的结果。如果要重新执行查询以获取新数据，则需要使用QueryBuilder构建另一个实例。
