        Description copied from interface: CuckooCommands
        Execute the command CF.ADD. Summary: Adds the specified element to the specified Cuckoo filter. Group: cuckoo

        If the cuckoo filter does not exist, it creates a new one.

        Specified by:
        cfadd in interface CuckooCommands<K,​V>

        key - the key
        value - the value, must not be null

                               V value)
        Description copied from interface: CuckooCommands
        Execute the command CF.ADDNX. Summary: Adds an item to a cuckoo filter if the item did not exist previously. Group: cuckoo

        If the cuckoo filter does not exist, it creates a new one.

        Specified by:
        cfaddnx in interface CuckooCommands<K,​V>
        Parameters:
        key - the key
