- 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
