Method Detail

addAsync

RFuture<Boolean> addAsync(V value,
                          long ttl,
                          TimeUnit unit)

Stores value with specified time to live. Value expires after specified time to live.

Parameters:

value - to add

ttl - - time to live for key\value entry. If 0 then stores infinitely.

unit - - time unit

Returns:

true if value has been added. false if value already been in collection.

sizeAsync

RFuture<Integer> sizeAsync()

Returns the number of elements in cache. This number can reflects expired elements too due to non realtime cleanup process.

Specified by:

sizeAsync in interface RCollectionAsync<V>

Returns:

size of set

readAllAsync

RFuture<Set<V>> readAllAsync()

Read all elements at once

Returns:

values

tryAddAsync

RFuture<Boolean> tryAddAsync(V... values)

Tries to add elements only if none of them in set.

Parameters:

values - - values to add

Returns:

true if elements successfully added, otherwise false.

tryAddAsync

RFuture<Boolean> tryAddAsync(long ttl,
                             TimeUnit unit,
                             V... values)

Tries to add elements only if none of them in set.

Parameters:

values - - values to add

ttl - - time to live for value. If 0 then stores infinitely.

unit - - time unit

Returns:

true if elements successfully added, otherwise false.
