NAME

       dnsjit.core.object.dns.label - Container of a DNS label

DESCRIPTION

       The  object  that  describes a DNS label.  To extract a domain name label first check that
       have_dn is set, then use offset + 1 to indicate where in the payload the label  start  and
       length for how many bytes long it is.

   Attributes
       is_end

       have_length
              Set if there is a length.

       have_offset
              Set if there is an offset.

       have_extension_bits
              Set if there is extension bits.

       have_dn
              Set if the label contained a domain name.

       extension_bits
              The extension bits.

       length The length of the domain name.

       offset If  have_dn  is  set then this contains the offset within the payload to where this
              label start otherwise it contains the offset to another label.

   Functions
       Label.new(size)
              Create a new array of labels.

       Label.tostring(dns, labels, num_labels, offset_labels)
              Returns labels as a string and an offset to the next label.  The string may be  nil
              if  the  first label was an offset.  The offset may be nil if the last label was an
              extension bits or end marker.

       Label.tooffstr(dns, labels, num_labels, offset_labels)
              Returns labels as a string which also includes a textual notation of the offset  in
              the form of <offset>label.
