Detailed Description

Interface for a state collection.

From a state collection you can retrieve the specific state you want. A state collection has one general state (usually the model state) and many other states comining from state modifiers. This interface only provides functions to gather states from the collection. The only thing you need is to call getState with the specific state properties object. Therefore state properties object pointer serves as the "ID" of the state in the collection, so it doesn't work to transfer a properties object with just the same properties but which is another instance. If the getState method is called without parameter, the "general" state is calculated.

Implementations of CStateCollections are CStateCollectionImpl and CState itself. The CState class can be seen as state collection only containing the CState object itself. This implentation was choosen in order to provide more generality for many functions.
