public class BacktrackTransformer
Model transformer for backtracking. This class parses the MoML of the given
model, and applies a renaming filter to the MoML. The actors with their
backtracking versions will be replaced. Actors without existing backtracking
versions will remain unchanged. Other entities in the model, such as
relations between ports, are kept. The resulting model supports backtracking
for the transformed actors.
Transform a model by replacing the actors with existing backtracking
versions, and return the resulting model.
Each transformed actor has a "_decorate" attribute. It adds a small
backtracking decoration to the actor's icon.
