tryAcquireAsync
public RFuture<Boolean> tryAcquireAsync(int permits)
Description copied from interface:RSemaphoreAsync
Acquires the given number of permits only if all are available at the time of invocation.Acquires a permits, if all are available and returns immediately, with the value
true
, reducing the number of available permits by given number of permitss.If no permits are available then this method will return immediately with the value
false
.- Specified by:
tryAcquireAsync
in interfaceRSemaphoreAsync
- Overrides:
tryAcquireAsync
in classRedissonSemaphore
- Parameters:
permits
- the number of permits to acquire- Returns:
true
if a permit was acquired andfalse
otherwise
-
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 interfaceRExpirable
- Parameters:
timeToLive
- - timeout before object will be deletedtimeUnit
- - timeout time unit- Returns:
true
if the timeout was set andfalse
if not
-
expireAsync
public RFuture<Boolean> expireAsync(long timeToLive, TimeUnit timeUnit)
Description copied from interface:RExpirableAsync
