org.infinispan.server.resp.RespCommand

org.infinispan.server.resp.commands.sortedset.ZRANK

All Implemented Interfaces:

Resp3Command

Direct Known Subclasses:

ZREVRANK

public class ZRANK
extends RespCommand
implements Resp3Command

Returns the rank of member in the sorted set stored at key, with the scores ordered from high to low. The rank (or index) is 0-based, which means that the member with the lowest score has rank 0. The optional WITHSCORE argument supplements the command's reply with the score of the element returned. Use ZREVRANK to get the rank of an element with the scores ordered from high to low. If member exists in the sorted set:

• using WITHSCORE, Array reply: an array containing the rank and score of member.
• without using WITHSCORE, Integer reply: the rank of member.

If member does not exist in the sorted set or key does not exist:

• using WITHSCORE, Array reply: nil.
• without using WITHSCORE, Bulk string reply: nil.

Since:

15.0
