Examples of org.apache.poi.poifs.storage.BlockAllocationTableReader

org.apache.poi.poifs.storage.BlockAllocationTableReader
This class manages and creates the Block Allocation Table, which is basically a set of linked lists of block indices.
Each block of the filesystem has an index. The first block, the header, is skipped; the first block after the header is index 0, the next is index 1, and so on.
A block's index is also its index into the Block Allocation Table. The entry that it finds in the Block Allocation Table is the index of the next block in the linked list of blocks making up a file, or it is set to -2: end of list. @author Marc Johnson (mjohnson at apache dot org)
