* Constraint of a given type may be defined only once * For a given constraint type, a constraint may only be added to an event chain if it is part of the current most fine-grained decomposition. I.e., it is the lowermost event chain for which also all siblings reference a constraint of the given type. * Constraints must be removed in a bottom-up fashion, i.e. subtree spanned by an event chain containing the current constraint C may only reference C. * Adds EventChain::getRootChain() Issue-Ref: 3470 Issue-Url: https://af3-developer.fortiss.org/issues/3470 Signed-off-by: Simon Barner <barner@fortiss.org>
