Method Detail

iterator

org.reactivestreams.Publisher<V> iterator(int count)

Returns an iterator over elements in this set. Elements are loaded in batch. Batch size is defined by count param.

Parameters:

count - - size of elements batch

Returns:

iterator

iterator

org.reactivestreams.Publisher<V> iterator(String pattern,
                                          int count)

Returns an iterator over elements in this set. Elements are loaded in batch. Batch size is defined by count param. If pattern is not null then only elements match this pattern are loaded.

Parameters:

pattern - - search pattern

count - - size of elements batch

Returns:

iterator

iterator

org.reactivestreams.Publisher<V> iterator(String pattern)

Returns iterator over elements in this set matches pattern.

Parameters:

pattern - - search pattern

Returns:

iterator

removeRandom

org.reactivestreams.Publisher<Set<V>> removeRandom(int amount)

Removes and returns random elements from set in async mode

Parameters:

amount - of random values

Returns:

random values

removeRandom

org.reactivestreams.Publisher<V> removeRandom()

Removes and returns random element from set in async mode

Returns:

value

random

org.reactivestreams.Publisher<V> random()

Returns random element from set in async mode

Returns:

value

move

org.reactivestreams.Publisher<Boolean> move(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
