        public void add​(Block block,
                        Object key)
        Adds a block to be managed by this instance. This method is usually called by the BlockContainer, you shouldn't need to call it directly.
        Specified by:
        add in interface Arrangement
        Parameters:
        block - the block.
        key - a key that controls the position of the block.
