      Specified by:
      visit in class Printer

      superName - the internal of name of the super class (see Type.getInternalName()). For interfaces, the super class is Object. May be null, but only for the Object class.
      interfaces - the internal names of the class's interfaces (see Type.getInternalName()). May be null.

    • visitSource

      public void visitSource(String file, String debug)

      Parameters:
      file - the name of the source file from which the class was compiled. May be null.

    • visitNestHost

      public void visitNestHost(String nestHost)
      Description copied from class: Printer
      Visits the nest host class of the class. A nest is a set of classes of the same package that share access to their private members.

This method must be called only once and only if the visited class is a non-host member of a nest. A class is implicitly its own nest, so it's invalid to call this method with the visited class name as argument.
      Overrides:
      visitNestHost in class Printer
      Parameters:
      nestHost - the internal name of the host class of the nest (see Type.getInternalName()).
