trySet

reactor.core.publisher.Mono<Boolean> trySet(V value)

Tries to set element atomically into empty holder.

Parameters:

value - - value to set

Returns:

true if successful, or false if element was already set

trySet

reactor.core.publisher.Mono<Boolean> trySet(V value,
                                            long timeToLive,
                                            TimeUnit timeUnit)

Tries to set element atomically into empty holder with defined timeToLive interval.

Parameters:

value - - value to set

timeToLive - - time to live interval

timeUnit - - unit of time to live interval

Returns:

true if successful, or false if element was already set

setIfExists

reactor.core.publisher.Mono<Boolean> setIfExists(V value)

Sets value only if it's already exists.

Parameters:

value - - value to set

Returns:

true if successful, or false if element wasn't set

setIfExists

reactor.core.publisher.Mono<Boolean> setIfExists(V value,
                                                 long timeToLive,
                                                 TimeUnit timeUnit)

Sets value only if it's already exists.

Parameters:

value - - value to set

timeToLive - - time to live interval

timeUnit - - unit of time to live interval

Returns:

true if successful, or false if element wasn't set

compareAndSet

reactor.core.publisher.Mono<Boolean> compareAndSet(V expect,

Atomically sets the value to the given updated value only if serialized state of the current value equals to serialized state of the expected value.

Parameters:

expect - the expected value

update - the new value

Returns:

true if successful; or false if the actual value was not equal to the expected value.
