SINTER

Syntax
SINTER key [key ...]
Available since:
1.0.0
Time complexity:
O(N*M) worst case where N is the cardinality of the smallest set and M is the number of sets.
ACL categories:
@read, @set, @slow,

返回所有给定集合的交集结果中的成员。

例如:

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

不存在的键被视为空集。 如果其中一个键是空集,结果集也是空的(因为与空集的交集总是产生空集)。

示例

SADD key1 "a" SADD key1 "b" SADD key1 "c" SADD key2 "c" SADD key2 "d" SADD key2 "e" SINTER key1 key2
