      • visitNestHost

        public void visitNestHost​(java.lang.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. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest. 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.

        Parameters:

        name - the name of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.
        descriptor - the descriptor of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.

        public void visitNestMember​(java.lang.String nestMember)
        Description copied from class: Printer
        Visits a member of the nest. A nest is a set of classes of the same package that share access to their private members. One of these classes, called the host, lists the other members of the nest, which in turn should link to the host of their nest. This method must be called only if the visited class is the host of a nest. A nest host is implicitly a member of its own nest, so it's invalid to call this method with the visited class name as argument.
