本文整理了Java中org.greenrobot.greendao.query.QueryBuilder.count方法的一些代码示例，展示了QueryBuilder.count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。QueryBuilder.count方法的具体详情如下：
包路径：org.greenrobot.greendao.query.QueryBuilder
类名称：QueryBuilder
方法名：count

QueryBuilder.count介绍

[英]Shorthand for QueryBuilder#buildCount(). CountQuery#count(); see CountQuery#count() for details. To execute a query more than once, you should build the query and keep the CountQuery object for efficiency reasons.
[中]QueryBuilder#buildCount（）的缩写。CountQuery#count（）；有关详细信息，请参见CountQuery#count（）。要多次执行查询，应构建查询并保留CountQuery对象，以提高效率。
