SINTER key [key ...]

自1.0.0起可用。

时间复杂度: O(N * M)最差情况,其中N是最小集合的基数,M是集合的数量。

返回由所有给定集合的交集所产生的集合的成员。

例如:

key1 = {a,b,c,d}key2 = {c}key3 = {a,c,e}SINTER key1 key2 key3 = {c}

不存在的键被认为是空集。www.8168.com_【官方首页】-百家乐论坛其中一个键是一个空集,结果集也是空的(因为与空集的交集总是导致一个空集)。

返回值

阵列回复:列出结果集的成员。

例子

redis>  SADD key1 "a" (integer) 1 

redis>  SADD key1 "b" (integer) 1 

redis>  SADD key1 "c" (integer) 1 

redis>  SADD key2 "c" (integer) 1 

redis>  SADD key2 "d" (integer) 1 

redis>  SADD key2 "e" (integer) 1 

redis>  SINTER key1 key2 1) "c"
