bi_by_ti_map_type

typedef std::unordered_map<const std::type_info*, BaseInfoBase*> SG::BaseInfoBaseImpl::bi_by_ti_map_type

Map of all type_info pointers to BaseInfoBase instances.

Used to canonicalize type_info instances.

Definition at line 82 of file BaseInfo.cxx.

ti_copyconversion_pair_type

typedef std::pair<const std::type_info*, const CopyConversionBase*> SG::BaseInfoBaseImpl::ti_copyconversion_pair_type

Hold copy conversion information indexed by @ type_info.

Definition at line 71 of file BaseInfo.cxx.

ti_copyconversion_type

typedef std::vector<ti_copyconversion_pair_type> SG::BaseInfoBaseImpl::ti_copyconversion_type

Definition at line 72 of file BaseInfo.cxx.

ti_map_pair_type

typedef std::pair<const std::type_info*, info> SG::BaseInfoBaseImpl::ti_map_pair_type

Member Function Documentation

findInfo()

const info* SG::BaseInfoBaseImpl::findInfo ( const std::type_info &  tinfo ) const

inline

Find a base by type_info.

Parameters

tinfo

The type_info to find.

Returns the info pointer for the base corresponding to info, or nullptr if there is no match.

Definition at line 118 of file BaseInfo.cxx.

  {
    // We don't expect there to be many entries, so just use a linear search.
    for (const auto& i : m_timap) {
      if (i.first == &tinfo)
        return &i.second;
    }
 
    // Sometimes type_info's are not actually unique, depending on how libraries
    // get loaded.  Try again, comparing names.
    for (const auto& i : m_timap) {
      if (strcmp (i.first->name(), tinfo.name()) == 0)
        return &i.second;
    }
    return nullptr;
