Method Detail

exists

boolean exists(String key)

exists

long exists(String... keys)

persist

long persist(String key)

type

String type(String key)

dump

byte[] dump(String key)

restore

String restore(String key,
               long ttl,
               byte[] serializedValue)

restore

String restore(String key,
               long ttl,
               byte[] serializedValue,
               RestoreParams params)

expire

long expire(String key,
            long seconds)

pexpire

long pexpire(String key,
             long milliseconds)

expireAt

long expireAt(String key,
              long unixTime)

pexpireAt

long pexpireAt(String key,
               long millisecondsTimestamp)

ttl

long ttl(String key)

pttl

long pttl(String key)

touch

long touch(String key)

touch

sort

List<String> sort(String key)

sort

long sort(String key,
          String dstkey)

sort

List<String> sort(String key,
                  SortingParams sortingParams)

sort

Read-only variant of the SORT command. It is exactly like the original SORT but refuses the STORE option and can safely be used in read-only replicas.

Parameters:

key - the key to sort

sortingParams - SortingParams

Returns:

list of sorted elements.
