Member Function Documentation

◆ findInfo()

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

Find a base by type_info.

Parameters
tinfoThe type_info to find.

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

119 {
120 // We don't expect there to be many entries, so just use a linear search.

122 if (i.first == &tinfo)
123 return &i.second;
124 }
125
126 // Sometimes type_info's are not actually unique, depending on how libraries
127 // get loaded. Try again, comparing names.
128 for (const auto& i : m_timap) {
