The creator and consumer of the collection have to have implicit knowledge about the index of a specific object inside of the collection. Go with a dedicated parameter or Data Transfer Object instead. There is only one exception for using Heterogenous Collection: If all objects in the collection implement a specific interface, this is acceptable.
