本文整理了Java中redis.clients.jedis.Jedis.scard()
方法的一些代码示例,展示了Jedis.scard()
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。Jedis.scard()
方法的具体详情如下:
包路径:redis.clients.jedis.Jedis
类名称:Jedis
方法名:scard
[英]Return the set cardinality (number of elements). If the key does not exist 0 is returned, like for empty sets.
[中]返回集合基数(元素数)。如果密钥不存在,则返回0,如空集。
