org.springframework.data.redis.connection.RedisZSetCommands.Weights

Enclosing interface:

RedisZSetCommands

public static class RedisZSetCommands.Weights
extends Object

Value object encapsulating a multiplication factor for each input sorted set. This means that the score of every element in every input sorted set is multiplied by this factor before being passed to the aggregation function.
