Multimap ist ein assoziativer Container, die eine sortierte Liste von Schlüssel-Wert-Paare enthält. Die Sortierung erfolgt nach der Vergleichsfunktion Compare, angewendet auf die Tasten durchgeführt. Suchen, Einfügen und Entfernen Operationen haben logarithmische Komplexität .

Original:

Multimap is an associative container that contains a sorted list of key-value pairs. Sorting is done according to the comparison function Compare, applied to the keys. Search, insertion, and removal operations have logarithmic complexity.
