{
int rows = Owner().NumRows();
if (sizes_.RowCount() != rows) {
sizes_.SetRowCount(rows);
}
_memos.SetSize(rows);

t4_i32 total = 0;
for (int r = 0; r < rows; ++r) {
int n = sizes_.GetInt(r);
d4_assert(n >= 0);
total += n;
_offsets.SetAt(r + 1, total);
}
d4_assert(total == _data.ColSize());
}
}示例2: iter
void c4_FormatB::Insert(int index_, const c4_Bytes& buf_, int count_)
{
d4_assert(count_ > 0);
_recalc = true;
int m = buf_.Size();
t4_i32 off = Offset(index_);
