示例1: row
void c4_Differ::ApplyDiff(int id_, c4_Column &col_)const {
d4_assert(0 <= id_ && id_ < _diffs.GetSize());
c4_View diff = pDiff(_diffs[id_]);
t4_i32 offset = 0;
for (int n = 0; n < diff.GetSize(); ++n) {
c4_RowRef row(diff[n]);
offset += pKeep(row);
c4_Bytes data;
pBytes(row).GetData(data);
// the following code is a lot like c4_MemoRef::Modify
const t4_i32 change = pResize(row);
if (change < 0)
col_.Shrink(offset, - change);
else if (change > 0)
col_.Grow(offset, change);
col_.StoreBytes(offset, data);
offset += data.Size();
}
if (offset > col_.ColSize())
col_.Shrink(offset, offset - col_.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_);
_memos.InsertAt(index_, 0, count_);
// insert the appropriate number of bytes
t4_i32 n = count_ * (t4_i32) m;
if (n > 0) {
_data.Grow(off, n);
// store as many copies as needed, but may have to do it in chunks
int spos = 0;
c4_ColIter iter (_data, off, off + n);
while (iter.Next(m - spos)) {
memcpy(iter.BufSave(), buf_.Contents() + spos, iter.BufLen());
spos += iter.BufLen();
if (spos >= m)
spos = 0;
}
d4_assert(spos == 0); // must have copied an exact multiple of the data
}
// define offsets of the new entries
_offsets.InsertAt(index_, 0, count_);
d4_assert(_offsets.GetSize() <= _memos.GetSize() + 1);
while (--count_ >= 0) {
_offsets.SetAt(index_++, off);
off += m;
}
d4_assert(index_ < _offsets.GetSize());
// adjust all following entries
while (index_ < _offsets.GetSize())
_offsets.ElementAt(index_++) += n;
d4_assert((t4_i32) _offsets.GetAt(index_ - 1) == _data.ColSize());
d4_assert(index_ <= _memos.GetSize() + 1);
