Parameters:

key - - map key

value - - map value

ttl - - time to live for key\value entry. If 0 then time to live doesn't affect entry expiration.

ttlUnit - - time unit

maxIdleTime - - max idle time for key\value entry. If 0 then max idle time doesn't affect entry expiration.

maxIdleUnit - - time unit

if maxIdleTime and ttl params are equal to 0 then entry stores infinitely.

Returns:

true if key is a new key in the hash and value was set. false if key already exists in the hash

                                  boolean replaceExistingValues,
                                  int parallelism)

Description copied from interface: RMapAsync

Loads map entries using MapLoader whose keys are listed in defined keys parameter.

Specified by:

loadAllAsync in interface RMapAsync<K,V>

Overrides:

loadAllAsync in class RedissonMap<K,V>

Parameters:

keys - - map keys

replaceExistingValues - - true if existed values should be replaced, false otherwise.

parallelism - - parallelism level, used to increase speed of process execution

Returns:

void

getLock

public RLock getLock(K key)

Description copied from interface: RMap

Returns RLock instance associated with key

Specified by:

getLock in interface RMap<K,V>

Overrides:

getLock in class RedissonMap<K,V>

Parameters:

key - - map key

Returns:

lock

getReadWriteLock

public RReadWriteLock getReadWriteLock(K key)

Description copied from interface: RMap

Returns RReadWriteLock instance associated with key

Specified by:

getReadWriteLock in interface RMap<K,V>

Overrides:

getReadWriteLock in class RedissonMap<K,V>

Parameters:

key - - map key

Returns:

readWriteLock

expire

public boolean expire(long timeToLive,
                      TimeUnit timeUnit)

Description copied from interface: RExpirable

Set a timeout for object. After the timeout has expired, the key will automatically be deleted.

Specified by:

expire in interface RExpirable

Parameters:

timeToLive - - timeout before object will be deleted

timeUnit - - timeout time unit

Returns:

true if the timeout was set and false if not

expireAt

public boolean expireAt(long timestamp)

Description copied from interface: RExpirable

Set an expire date for object. When expire date comes the key will automatically be deleted.

Specified by:

expireAt in interface RExpirable

Parameters:

timestamp - - expire date in milliseconds (Unix timestamp)

Returns:

true if the timeout was set and false if not

expireAt

public boolean expireAt(Date timestamp)

Description copied from interface: RExpirable

Set an expire date for object. When expire date comes the key will automatically be deleted.

Specified by:

expireAt in interface RExpirable

Parameters:

timestamp - - expire date

Returns:

true if the timeout was set and false if not

clearExpire

public boolean clearExpire()

Description copied from interface: RExpirable

Clear an expire timeout or expire date for object.

Specified by:

clearExpire in interface RExpirable

Returns:

true if timeout was removed false if object does not exist or does not have an associated timeout

remainTimeToLive

public long remainTimeToLive()

Description copied from interface: RExpirable

Remaining time to live of Redisson object that has a timeout

Specified by:

remainTimeToLive in interface RExpirable

Returns:

time in milliseconds -2 if the key does not exist. -1 if the key exists but has no associated expire.
