Method Detail

size

io.reactivex.Single<Long> size()

Returns size of object in bytes

Returns:

object size

trySet

io.reactivex.Single<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

io.reactivex.Single<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

compareAndSet

io.reactivex.Single<Boolean> compareAndSet(V expect,
                                           V update)

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.

getAndSet

io.reactivex.Maybe<V> getAndSet(V newValue)

Retrieves current element in the holder and replaces it with newValue.

Parameters:

newValue - - value to set

Returns:

previous value

getAndSet

io.reactivex.Maybe<V> getAndSet(V value,
                                long timeToLive,
                                TimeUnit timeUnit)

Retrieves current element in the holder and replaces it with newValue with defined timeToLive interval.

Parameters:

value - - value to set

timeToLive - - time to live interval

timeUnit - - unit of time to live interval

Returns:

previous value

get

io.reactivex.Maybe<V> get()

Retrieves element stored in the holder.

Returns:

element

getAndDelete

io.reactivex.Maybe<V> getAndDelete()

Retrieves element in the holder and removes it.

Returns:

element

set

io.reactivex.Completable set(V value)

Stores element into the holder.

Parameters:

value - - value to set

Returns:

void

set

io.reactivex.Completable set(V value,
                             long timeToLive,
                             TimeUnit timeUnit)

Stores element into the holder with defined timeToLive interval.

Parameters:

value - - value to set

timeToLive - - time to live interval

timeUnit - - unit of time to live interval

Returns:

void
