  ptolemy.backtrack.ui.BacktrackTransformer

public class BacktrackTransformer
extends java.lang.Object

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.
