start | an iterator which points to where the header should read from. |
This method is used by Packet::RemoveHeader to re-create a header from the byte buffer of a packet. The data read is expected to match bit-for-bit the representation of this header in real networks.
Note that data is not actually removed from the buffer to which the iterator points. Both Packet::RemoveHeader() and Packet::PeekHeader() call Deserialize(), but only the RemoveHeader() has additional statements to remove the header bytes from the underlying buffer and associated metadata.

os | output stream This method is used by Packet::Print to print the content of a header as ascii data to a c++ output stream. Although the header is free to format its output as it wishes, it is recommended to follow a few rules to integrate with the packet pretty printer: start with flags, small field values located between a pair of parens. Values should be separated by whitespace. Follow the parens with the important fields, separated by whitespace. i.e.: (field1 val1 field2 val2 field3 val3) field4 val4 field5 val5 |
