Constructor Detail

SortsetDatatypeOperations

public SortsetDatatypeOperations()

Method Detail

zadd

public Long zadd(byte[] key,
                 double score,
                 byte[] member)

zadd

public Long zadd(byte[] key,
                 Map<Double,byte[]> scoreMembers)

Add the specified member having the specifeid score to the sorted set stored at key. If member is already a member of the sorted set the score is updated, and the element reinserted in the right position to ensure sorting. If key does not exist a new sorted set with the specified member as sole member is crated. If the key exists but does not hold a sorted set value an error is returned.

The score value can be the string representation of a double precision floating point number.

Parameters:

key -

score -

member -

Returns:

Integer reply, specifically: 1 if the new element was added 0 if the element was already a member of the sorted set and the score was updated

zcard

public Long zcard(byte[] key)

Return the sorted set cardinality (number of elements). If the key does not exist 0 is returned, like for empty sorted sets.

Time complexity O(1)

Parameters:

key -

Returns:

the cardinality (number of elements) of the set as an integer.

zcount

public Long zcount(byte[] key,
                   double min,
                   double max)

zcount

public Long zcount(byte[] key,
                   byte[] min,
                   byte[] max)

zincrby

public Double zincrby(byte[] key,
                      double score,
                      byte[] member)

If member already exists in the sorted set adds the increment to its score and updates the position of the element in the sorted set accordingly. If member does not already exist in the sorted set it is added with increment as score (that is, like if the previous score was virtually zero). If key does not exist a new sorted set with the specified member as sole member is crated. If the key exists but does not hold a sorted set value an error is returned.

The score value can be the string representation of a double precision floating point number. It's possible to provide a negative value to perform a decrement.

For an introduction to sorted sets check the Introduction to Redis data types page.

Time complexity O(log(N)) with N being the number of elements in the sorted set

Parameters:

key -

score -

member -

Returns:

The new score

zunionstore

public Long zunionstore(byte[] dstkey,
                        byte[]... sets)

Creates a union or intersection of N sorted sets given by keys k1 through kN, and stores it at dstkey. It is mandatory to provide the number of input keys N, before passing the input keys and the other (optional) arguments.

As the terms imply, the ZINTERSTORE command requires an element to be present in each of the given inputs to be inserted in the result. The ZUNIONSTORE command inserts all elements across all inputs.

Using the WEIGHTS option, it is possible to add weight to each input sorted set. This means that the score of each element in the sorted set is first multiplied by this weight before being passed to the aggregation. When this option is not given, all weights default to 1.

With the AGGREGATE option, it's possible to specify how the results of the union or intersection are aggregated. This option defaults to SUM, where the score of an element is summed across the inputs where it exists. When this option is set to be either MIN or MAX, the resulting set will contain the minimum or maximum score of an element across the inputs where it exists.

Time complexity: O(N) + O(M log(M)) with N being the sum of the sizes of the input sorted sets, and M being the number of elements in the resulting sorted set

Parameters:

dstkey -

sets -

Returns:

Integer reply, specifically the number of elements in the sorted set at dstkey

                        redis.clients.jedis.ZParams params,
                        byte[]... sets)

zrange

public Set<byte[]> zrange(byte[] key,
                          int start,
                          int end)

zrangeWithScores

public Set<SortsetDatatypeOperations.ScoredByteBuffer> zrangeWithScores(byte[] key,
                                                                        int start,
                                                                        int end)

zrangeByScore

public Set<byte[]> zrangeByScore(byte[] key,
                                 double min,
                                 double max)

Return the all the elements in the sorted set at key with a score between min and max (including elements with score equal to min or max).

The elements having the same score are returned sorted lexicographically as ASCII strings (this follows from a property of Redis sorted sets and does not involve further computation).

Using the optional LIMIT it's possible to get only a range of the matching elements in an SQL-alike way. Note that if offset is large the commands needs to traverse the list for offset elements and this adds up to the O(M) figure.

The ZCOUNT command is similar to ZRANGEBYSCORE but instead of returning the actual elements in the specified interval, it just returns the number of matching elements.

Exclusive intervals and infinity

min and max can be -inf and +inf, so that you are not required to know what's the greatest or smallest element in order to take, for instance, elements "up to a given value".

Also while the interval is for default closed (inclusive) it's possible to specify open intervals prefixing the score with a "(" character, so for instance:

ZRANGEBYSCORE zset (1.3 5

Will return all the values with score > 1.3 and <= 5, while for instance:

ZRANGEBYSCORE zset (5 (10

Will return all the values with score > 5 and < 10 (5 and 10 excluded).

Time complexity:

O(log(N))+O(M) with N being the number of elements in the sorted set and M the number of elements returned by the command, so if M is constant (for instance you always ask for the first ten elements with LIMIT) you can consider it O(log(N))

Parameters:

key -

min -

max -

Returns:

Multi bulk reply specifically a list of elements in the specified score range.

zrank

public Long zrank(byte[] key,
                  byte[] member)

Return the rank (or index) or member in the sorted set at key, with scores being ordered from low to high.

When the given member does not exist in the sorted set, the special value 'nil' is returned. The returned rank (or index) of the member is 0-based for both commands.

Time complexity:

O(log(N))

Parameters:

key -

member -

Returns:

Integer reply or a nil bulk reply, specifically: the rank of the element as an integer reply if the element exists. A nil bulk reply if there is no such element.

zrevrank(byte[], byte[])

zrem

public Long zrem(byte[] key,
                 byte[]... members)

Remove the specified member from the sorted set value stored at key. If member was not a member of the set no operation is performed. If key does not not hold a set value an error is returned.

Parameters:

key -

members -

Returns:

The number of members removed from the sorted set, not including non existing members.

zremrangeByRank

public Long zremrangeByRank(byte[] key,
                            int start,
                            int end)

Remove all elements in the sorted set at key with rank between start and end. Start and end are 0-based with rank 0 being the element with the lowest score. Both start and end can be negative numbers, where they indicate offsets starting at the element with the highest rank. For example: -1 is the element with the highest score, -2 the element with the second highest score and so forth.

Time complexity: O(log(N))+O(M) with N being the number of elements in the sorted set and M the number of elements removed by the operation

zremrangeByScore

public Long zremrangeByScore(byte[] key,
                             double start,
                             double end)

Remove all the elements in the sorted set at key with a score between min and max (including elements with score equal to min or max).

Time complexity:

Parameters:

key -

start -

end -

Returns:

Integer reply, specifically the number of elements removed.
