Package org.btrplace.scheduler.choco.transition

Different classes to model the possible state transitions for a VM or a node. The most common entry point is TransitionFactory that will pick up the right model according to the initial and the next state of an element. Once the associated ReconfigurationProblem solved, the associated transitions will generate Action.
