How do you create a Collection of GenuineVariableDescriptors?

Question

I'm trying to implement my own MoveListFactory and don't know how to access / create the variable descriptors for the move I want to instantiate. The createMoveList method (from the MoveListFactory interface) takes a single argument of an instance of my Solution class. From this I can access all the planning variables that I need to create a ChainSwapMove. What I'm unsure about is how to create the first argument that the ChainSwapMove constructor requires (e.g. the Collection<GenuineVariableDescriptor>). The example in the documentation doesn't shed any light on this process since the custom move used in the NQueens example doesn't require this Collection of GenuineVariableDescriptors. I've not come across any examples of how someone can access these from only the information contained in a Solution object.

Answer 1

Anything ending with *Descriptor is very internal API, not the kind of classes I want users to be using. The docs presume you build your own move (which is difficult indeed to build a valid move on chained variables that leaves the chain in a valid state).

That being said, here's a clue: InnerScoreDirector.getSolutionDescriptor().getEntityDescripor(MyCustomer.class).getVariableDescriptor("myPreviousStandstill") ...
