I use MapContainerImpl with IndexTypes.DISK_INDEX index type。
Suppose I add
for elements A, B, C, D by order, then I delete D. And then I
delete B.After
these operations, the indice is wrong.Because after I insert for
elements,
Indice is A->B->C->D. I delete D， then A->B-C。But notice in
memory, last
variable in DiskIndexLinkedList is not as same as file。The last's
next
points D. Then I delete B，codes in MapContainerImpl set A'next to
C and
C'prev to A and writes them back.Then error occurs. This is because
when
DiskIndexLinkedList find result is euqal to root or last, it's simplly
return root or last,actually, if is root, DiskIndexLinkedList
should update
the content of root object(Can not simplly root = result). If it is
last,
DiskIndexLinkedList can use last = result to update the content of
last.
