示例1: SortedCopy
void SortedCopy(const SparseVector& in_vec, SparseVector* out_vec){
// START: Disable after debug!!
// Make sure there are no duplicate indices in input
{
std::set<uint64> prev_indices;
for (int i=0; i < in_vec.indices_size(); ++i){
uint64 cur_index = in_vec.indices(i);
CHECK(!scul::Contains(prev_indices, cur_index)) << "cur_index: " << cur_index;
prev_indices.insert(cur_index);
}
}
// END
CHECK(out_vec);
out_vec->Clear();
scul::Permutation p;
p.InitSortingPermutation(in_vec.indices());
CHECK_EQ(p.size(), in_vec.indices_size());
ResizeRepeatedField(out_vec->mutable_indices(), p.size());
ResizeRepeatedField(out_vec->mutable_values(), p.size());
p.Apply(in_vec.indices(), out_vec->mutable_indices());
