Method Detail

removeRandomAsync

RFuture<Set<V>> removeRandomAsync(int amount)

Removes and returns random elements from set in async mode

Parameters:

amount - of random values

Returns:

random values

removeRandomAsync

RFuture<V> removeRandomAsync()

Removes and returns random element from set in async mode

Returns:

value

randomAsync

RFuture<V> randomAsync()

Returns random element from set in async mode

Returns:

value

randomAsync

RFuture<Set<V>> randomAsync(int count)

Returns random elements from set limited by count

Parameters:

count - - values amount to return

Returns:

value

moveAsync

RFuture<Boolean> moveAsync(String destination,
                           V member)

Move a member from this set to the given destination set in async mode.

Parameters:

destination - the destination set

member - the member to move

Returns:

true if the element is moved, false if the element is not a member of this set or no operation was performed

readAllAsync

RFuture<Set<V>> readAllAsync()

Read all elements at once

Returns:

values

unionAsync

RFuture<Integer> unionAsync(String... names)

Union sets specified by name and write to current set. If current set already exists, it is overwritten.

Parameters:

names - - name of sets

Returns:

size of union

readUnionAsync

RFuture<Set<V>> readUnionAsync(String... names)

Union sets specified by name with current set. Without current set state change.

Parameters:

names - - name of sets

Returns:

values

diffAsync

RFuture<Integer> diffAsync(String... names)

Diff sets specified by name and write to current set. If current set already exists, it is overwritten.

Parameters:

names - - name of sets

Returns:

size of diff

readDiffAsync

RFuture<Set<V>> readDiffAsync(String... names)

Diff sets specified by name with current set. Without current set state change.

Parameters:

names - - name of sets

Returns:

values

intersectionAsync

RFuture<Integer> intersectionAsync(String... names)

Intersection sets specified by name and write to current set. If current set already exists, it is overwritten.

Parameters:

names - - name of sets

Returns:

size of intersection

readIntersectionAsync

RFuture<Set<V>> readIntersectionAsync(String... names)

Intersection sets specified by name with current set. Without current set state change.

Parameters:

names - - name of sets

Returns:

values

tryAddAsync

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

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

Parameters:
