Net::Frame::Layer::UDP - User Datagram Protocol layer object

srcdst Source and destination ports.

       length
           The length in bytes of the datagram, including layer 7 payload (that is, layer 4 + layer 7).

       checksum
           Checksum of the datagram.

       The following are inherited attributes. See Net::Frame::Layer for more information.

       This modules implements the encoding and decoding of the UDP layer.

       See also Net::Frame::Layer for other attributes and methods.

newnew (hash)
           Object  constructor.  You  can  pass  attributes  that  will overwrite default ones. See SYNOPSIS for
           default values.

       computeLengths
           Computes various lengths contained within this layer.

       computeChecksums ({ type => PROTO, src => IP, dst => IP })
           In order to compute checksums of TCP, you need to pass the protocol type (IPv4, IPv6), the source and
           destination IP addresses (IPv4 for IPv4, IPv6 for IPv6).

       getKeygetKeyReverse
           These  two  methods  are  basically  used  to  increase  the  speed  when  using  recv  method   from
           Net::Frame::Simple. Usually, you write them when you need to write match method.

       match (Net::Frame::Layer::UDP object)
           This method is mostly used internally. You pass a Net::Frame::Layer::UDP layer as a parameter, and it
           returns true if this is a response corresponding for the request, or returns false if not.

       The  following  are  inherited methods. Some of them may be overridden in this layer, and some others may
       not be meaningful in this layer. See Net::Frame::Layer for more information.
