Method Summary

Modifier and Type	Method	Description
RFuture<Boolean>	compareAndSetAsync(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.
RFuture<V>	getAndDeleteAsync()	Retrieves element in the holder and removes it.
RFuture<V>	getAndSetAsync(V newValue)	Retrieves current element in the holder and replaces it with newValue.
RFuture<V>	getAsync()	Retrieves element stored in the holder.
RFuture<Void>	setAsync(V value)	Stores element into the holder.
RFuture<Void>	setAsync(V value, long timeToLive, TimeUnit timeUnit)	Stores element into the holder with defined timeToLive interval.
RFuture<Long>	sizeAsync()	Returns size of object in bytes
RFuture<Boolean>	trySetAsync(V value)	Tries to set element atomically into empty holder.
RFuture<Boolean>	trySetAsync(V value, long timeToLive, TimeUnit timeUnit)	Tries to set element atomically into empty holder with defined timeToLive interval.

Method Detail

sizeAsync

RFuture<Long> sizeAsync()

Returns size of object in bytes

Returns:

object size

getAsync

RFuture<V> getAsync()

Retrieves element stored in the holder.

Returns:

element

getAndDeleteAsync

RFuture<V> getAndDeleteAsync()

Retrieves element in the holder and removes it.

Returns:

element

trySetAsync

RFuture<Boolean> trySetAsync(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

trySetAsync

RFuture<Boolean> trySetAsync(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

compareAndSetAsync

RFuture<Boolean> compareAndSetAsync(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.

getAndSetAsync

RFuture<V> getAndSetAsync(V newValue)

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

Parameters:

newValue - - value to set

Returns:

previous value

setAsync

RFuture<Void> setAsync(V value)

Stores element into the holder.

Parameters:

value - - value to set

Returns:

void

setAsync

RFuture<Void> setAsync(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
