      • iterator

        Iterator<Field> iterator()
        Returns an iterator over the list of fields of this header.
        Specified by:
        iterator in interface Iterable<Field>

      • removeFields

        number of fields removed.

      • setField

        void setField​(Field field)
        Sets or replaces a field. This method is useful for header fields such as Subject or Message-ID that should not occur more than once in a message. If this Header does not already contain a header field of the same name as the given field then it is added to the end of the list of fields (same behavior as addField(Field)). Otherwise the first occurrence of a field with the same name is replaced by the given field and all further occurrences are removed.
        Parameters:
        field - the field to set.
