Method Detail

expire

boolean expire(long timeToLive,
               TimeUnit timeUnit)

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

Parameters:

timeToLive - - timeout before object will be deleted

timeUnit - - timeout time unit

Returns:

true if the timeout was set and false if not

expireAt

boolean expireAt(long timestamp)

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

Parameters:

timestamp - - expire date in milliseconds (Unix timestamp)

Returns:

true if the timeout was set and false if not

expireAt

boolean expireAt(Date timestamp)

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

Parameters:

timestamp - - expire date

Returns:

true if the timeout was set and false if not

clearExpire

boolean clearExpire()

Clear an expire timeout or expire date for object.

Returns:

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

remainTimeToLive

long remainTimeToLive()

Remaining time to live of Redisson object that has a timeout

Returns:

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