Containment is managed by functions of the containing classes. For example, AcMapSession contains an AcMapAliases object through the AcMapSession::GetAliases function, and AcMapAliases in turn contains one or more AcMapDriveAlias objects through the AcMapAliases::GetAlias function. AcMapAliases has other functions as well for managing containment: functions to add, count, remove, and so on.
