Like all OsidLists, BlockList provides a means for accessing Block elements sequentially either one at a time or many at a time. Examples:

                     
                     
                     while (bl.hasNext()) {
                          Block block = bl.getNextBlock();
                     }
                     
                                 
                     
                

                     
                     
                     while (bl.hasNext()) {
                          Block[] blocks = bl.getNextBlocks(bl.available());
                     }
