Note-se que os operadores de comparação para
shared_ptr simplesmente comparar valores de ponteiro, os objetos reais são apontou para não comparados. Tendo operator< definido para shared_ptr permite shared_ptrs a ser utilizados como chaves em recipientes associativos, gosto e std::map std::set.Original:
Note that the comparison operators for
shared_ptr simply compare pointer values; the actual objects pointed to are not compared. Having operator< defined for shared_ptr allows shared_ptrs to be used as keys in associative containers, like std::map and std::set.The text has been machine-translated via Google Translate.
