Class ZStoreArgs

java.lang.Object

io.lettuce.core.ZAggregateArgs

io.lettuce.core.ZStoreArgs

All Implemented Interfaces:

CompositeArgument

public class ZStoreArgs
extends ZAggregateArgs

Argument list builder for the Redis ZUNIONSTORE and ZINTERSTORE commands. Static import the methods from ZStoreArgs.Builder and chain the method calls: weights(1, 2).max().

ZAddArgs is a mutable object and instances should be used only once to avoid shared mutable state.
