Method Detail
-
finish
public RedisObject[] finish()
Send all pending commands in the pipeline and returns all of their return values.- Returns:
- an array of Redis objects whose contents are in the order of the commands issued.
-
echo
public void echo(String message)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/echo:
Available since 1.0.0.
- Specified by:
echo
in interfaceRedisDeferredCommands
-
del
public void del(String key, String... keys)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/del:
Available since 1.0.0.
Time complexity: O(N) where N is the number of keys that will be removed. When a key to remove holds a value other than a string, the individual complexity for this key is O(M) where M is the number of elements in the list, set, sorted set or hash. Removing a single key that holds a string value is O(1).
Removes the specified keys. A key is ignored if it does not exist.
- Specified by:
del
in interfaceRedisDeferredCommands
- Parameters:
key
- the first key to delete.keys
- the additional keys to delete.
-
dump
public void dump(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/dump:
Available since 2.6.0.
Time complexity: O(1) to access the key and additional O(N*M) to serialized it, where N is the number of Redis objects composing the value and M their average size. For small string values the time complexity is thus O(1)+O(1*M) where M is small, so simply O(1).
Serialize the value stored at key in a Redis-specific format and return it to the user. The returned value can be synthesized back into a Redis key using the
RedisDeferredCommands.restore(java.lang.String, long, java.lang.String)
command.- Specified by:
dump
in interfaceRedisDeferredCommands
-
exists
public void exists(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/exists:
Available since 1.0.0.
Time complexity: O(1)
Returns if
key
exists.- Specified by:
exists
in interfaceRedisDeferredCommands
-
expire
public void expire(String key, long seconds)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/expire:
Available since 1.0.0.
Time complexity: O(1)
Set a timeout on
key
. After the timeout has expired, the key will automatically be deleted. A key with an associated timeout is often said to be volatile in Redis terminology.- Specified by:
expire
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to expire.seconds
- the time-to-live in seconds.
-
expireat
public void expireat(String key, long timestamp)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/expireat:
Available since 1.2.0.
Time complexity: O(1)
expireat has the same effect and semantic as
RedisDeferredCommands.expire(java.lang.String, long)
, but instead of specifying the number of seconds representing the TTL (time to live), it takes an absolute Unix timestamp (seconds since January 1, 1970).- Specified by:
expireat
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to expire.timestamp
- the timestamp in from-Epoch milliseconds.
-
keys
public void keys(String pattern)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/keys:
Available since 1.0.0.
Time complexity: O(N) with N being the number of keys in the database, under the assumption that the key names in the database and the given pattern have limited length.
Returns all keys matching
pattern
.- Specified by:
keys
in interfaceRedisDeferredCommands
- Parameters:
pattern
- a wildcard pattern for matching key names.
-
move
public void move(String key, long db)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/move:
Available since 1.0.0.
Time complexity: O(1)
Move
key
from the currently selected database to the specified destination database. Whenkey
already exists in the destination database, or it does not exist in the source database, it does nothing. It is possible to use MOVE as a locking primitive because of this.- Specified by:
move
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to move.db
- the target database.
-
persist
public void persist(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/persist:
Available since 2.2.0.
Time complexity: O(1)
Remove the existing timeout on
key
, turning the key from volatile (a key with an expire set) to persistent (a key that will never expire as no timeout is associated).- Specified by:
persist
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to persist (remove TTL).
-
pexpire
public void pexpire(String key, long milliseconds)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/pexpire:
Available since 2.6.0.
Time complexity: O(1)
This command works exactly like
RedisDeferredCommands.expire(java.lang.String, long)
but the time to live of the key is specified in milliseconds instead of seconds.- Specified by:
pexpire
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to expire.milliseconds
- the time-to-live in milliseconds.
-
pexpireat
public void pexpireat(String key, long timestamp)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/pexpireat:
Available since 2.6.0.
Time complexity: O(1)
PEXPIREAT has the same effect and semantic as
RedisDeferredCommands.expireat(java.lang.String, long)
, but the Unix time at which the key will expire is specified in milliseconds instead of seconds.- Specified by:
pexpireat
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to expire.timestamp
- the timestamp in from-Epoch milliseconds.
-
pttl
public void pttl(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/pttl:
Available since 2.6.0.
Time complexity: O(1)
Like
RedisDeferredCommands.ttl(java.lang.String)
, this command returns the remaining time to live of a key that has an expire set, with the sole difference that TTL returns the amount of remaining time in seconds while PTTL returns it in milliseconds.- Specified by:
pttl
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to inspect.
-
publish
public void publish(String channel, String message)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/publish:
Available since 2.0.0.
Time complexity: O(N+M) where N is the number of clients subscribed to the receiving channel and M is the total number of subscribed patterns (by any client).
Posts a message to the given channel.
- Specified by:
publish
in interfaceRedisDeferredCommands
-
randomkey
public void randomkey()
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/randomkey:
Available since 1.0.0.
Time complexity: O(1)
Return a random key from the currently selected database.
- Specified by:
randomkey
in interfaceRedisDeferredCommands
-
rename
public void rename(String key, String newkey)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/rename:
Available since 1.0.0.
Time complexity: O(1)
Renames
key
tonewkey
. It returns an error when the source and destination names are the same, or whenkey
does not exist. Ifnewkey
already exists it is overwritten, when this happensRedisDeferredCommands.rename(java.lang.String, java.lang.String)
executes an implicitRedisDeferredCommands.del(java.lang.String, java.lang.String...)
operation, so if the deleted key contains a very big value it may cause high latency even ifRedisDeferredCommands.rename(java.lang.String, java.lang.String)
itself is usually a constant-time operation.- Specified by:
rename
in interfaceRedisDeferredCommands
- Parameters:
key
- the old name.newkey
- the new name.
-
renamenx
public void renamenx(String key, String newkey)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/renamenx:
Available since 1.0.0.
Time complexity: O(1)
Renames
key
tonewkey
ifnewkey
does not yet exist. It returns an error under the same conditions asRedisDeferredCommands.rename(java.lang.String, java.lang.String)
.- Specified by:
renamenx
in interfaceRedisDeferredCommands
- Parameters:
key
- the old name.newkey
- the new name.
-
restore
public void restore(String key, long ttl, String serializedvalue)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/restore:
Available since 2.6.0.
Time complexity: O(1) to create the new key and additional O(N*M) to recostruct the serialized value, where N is the number of Redis objects composing the value and M their average size. For small string values the time complexity is thus O(1)+O(1*M) where M is small, so simply O(1). However for sorted set values the complexity is O(N*M*log(N)) because inserting values into sorted sets is O(log(N)).
Create a key associated with a value that is obtained by deserializing the provided serialized value (obtained via
RedisDeferredCommands.dump(java.lang.String)
).- Specified by:
restore
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to restore.ttl
- the time-to-live in milliseconds.serializedvalue
- the serialized value (from aRedisDeferredCommands.dump(java.lang.String)
call).
-
sort
public void sort(String key, String pattern, SortOrder sortOrder, boolean alpha, Long limitOffset, Long limitCount, String storeKey, String... getPatterns)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/sort:
Available since 1.0.0.
Time complexity: O(N+M*log(M)) where N is the number of elements in the list or set to sort, and M the number of returned elements. When the elements are not sorted, complexity is currently O(N) as there is a copy step that will be avoided in next releases.
Returns or stores the elements contained in the list, set, or sorted set at
key
. By default, sorting is numeric and elements are compared by their value interpreted as double precision floating point number.- Specified by:
sort
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to sort the contents of.pattern
- if not null,sortOrder
- if true, sort descending. if false or null, sort ascending.alpha
- if true, sort lexicographically, not by a score.limitOffset
- if not null, the starting offset into the list (0-based).limitCount
- if not null, the amount of objects from the offset to sort. else, return all the way to the end.storeKey
- if not null, this is the key to store the result in.getPatterns
- the patterns for finding the sort score.
-
ttl
public void ttl(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/ttl:
Available since 1.0.0.
Time complexity: O(1)
Returns the remaining time to live of a key that has a timeout. This introspection capability allows a Redis client to check how many seconds a given key will continue to be part of the dataset.
- Specified by:
ttl
in interfaceRedisDeferredCommands
- Parameters:
key
- the key to inspect.
-
type
public void type(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/type:
Available since 1.0.0.
Time complexity: O(1)
Returns the string representation of the type of the value stored at
key
.- Specified by:
type
in interfaceRedisDeferredCommands
-
append
public void append(String key, String value)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/append:
Available since 2.0.0.
Time complexity: O(1). The amortized time complexity is O(1) assuming the appended value is small and the already present value is of any size, since the dynamic string library used by Redis will double the free space available on every reallocation.
If
key
already exists and is a string, this command appends thevalue
at the end of the string. Ifkey
does not exist it is created and set as an empty string, so APPEND will be similar to SET in this special case.- Specified by:
append
in interfaceRedisDeferredCommands
-
bitcount
public void bitcount(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/bitcount:
Available since 2.6.0.

- Specified by:
bitcount
in interfaceRedisDeferredCommands
-

public void get(String key)
Description copied from interface:RedisDeferredCommands
From http://redis.io/commands/get:
Available since 1.0.0.
Time complexity: O(1)
