Method Detail

expire

org.reactivestreams.Publisher<Boolean> expire(long timeToLive,
                                              TimeUnit timeUnit)

Set a timeout for object in mode. 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

org.reactivestreams.Publisher<Boolean> expireAt(Date timestamp)

Set an expire date for object in mode. 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

expireAt

org.reactivestreams.Publisher<Boolean> expireAt(long timestamp)

Set an expire date for object in mode. 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

clearExpire

org.reactivestreams.Publisher<Boolean> clearExpire()

Clear an expire timeout or expire date for object in mode. Object will not be deleted.

Returns:

true if the timeout was cleared and false if not

remainTimeToLive

org.reactivestreams.Publisher<Long> remainTimeToLive()

Get remaining time to live of object in milliseconds.

Returns:

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