    • add

      public void add​(Block block, Object key)
      Adds a block and a key which can be used to determine the position of the block in the arrangement. This method is called by the container (you don't need to call this method directly) and gives the arrangement an opportunity to record the details if they are required.
      Specified by:
      add in interface Arrangement
      Parameters:
      block - the block.
      key - the key (null permitted).
