std::map ist ein sortierter assoziativer Container, welcher Schlüssel-Wert-Paare mit einzigartigen Schlüssel enthält. Schlüssel werden mithilfe der Vergleichsfunktion Compare sortiert. Operationen zum Suchen, Entfernen und Einfügen haben logarithmische Komplexität. Paare sind in der Regel als Rot-Schwarz-Bäume umgesetzt .
Original:
std::map is a sorted associative container that contains key-value pairs with unique keys. Keys are sorted by using the comparison function Compare. Search, removal, and insertion operations have logarithmic complexity. Maps are usually implemented as Rot-Schwarz-Bäume.
