Detailed Description

The impl_utils namespace contains implementation-utilities. Helpers for implementation code, not part of the public API.

Function Documentation

void fei::impl_utils::find_offsets ( const std::vector< int > &  sources,
const std::vector< int > &  targets,
std::vector< int > &  offsets 

Given a vector of sources and a vector of targets, fill the offsets vector such that if offsets[i] >= 0, then sources[i] == targets[offsets[i]]. For any i such that sources[i] is not found in targets, then offsets[i] == -1. The offsets vector will have length equal to the length of sources.

For efficiency, it is assumed that both sources and targets are sorted.

void fei::impl_utils::pack_FillableMat ( const fei::FillableMat mat,
std::vector< int > &  intdata,
std::vector< double > &  doubledata 

pack an fei::FillableMat object into a pair of std::vector objects.

void fei::impl_utils::unpack_FillableMat ( const std::vector< int > &  intdata,
const std::vector< double > &  doubledata,
fei::FillableMat mat,
bool  clear_mat_on_entry = true,
bool  overwrite_entries = true 

unpack a pair of std::vector objects into an fei::FillableMat object. The std::vector objects are assumed to have been produced by the function pack_FillableMat(...).
