- ## Method Details

  - ### addOldVariableMethodNode

    public static void addOldVariableMethodNode(ClassNode classNode)
    Creates a synthetic method handling generation of the `old` variable map. If a super class declares the same synthetic method it will be called and the results will be merged.
    Parameters:
      `classNode` - which contains postconditions, so an old variable generating method makes sense here.
