Method Detail

removeRandom

V removeRandom()

Removes and returns random element from set

Returns:

move

boolean move(String destination,
           V member)

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

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

readAll
