It returns either `BlockCopyData`, containing copy metadata, or `null`. A `null` return value signifies that the block is an insertion marker. This method's primary action is to prepare a block for duplication, distinguishing between regular blocks and insertion markers. The output indicates the data structure that contains the necessary information for the copy.\n"]]
