- /* Please consider the following comments on the implementation given in this class:
- * 1. you could think of simply using SENF_PARSER_PRIVATE_VARIANT and List / Vectorparser like this:
- * SENF_PARSER_PRIVATE_VARIANT ( fbiplist, ip_version,
- * (senf::VoidPacketParser) //ip_version=0
- * (senf::VoidPacketParser) //1
- * (senf::VoidPacketParser) //2
- * (senf::VoidPacketParser) //3
- * (senf::Parse_ListB< IPv4Packet, num_of_fbips>) //4
- * (senf::VoidPacketParser) //5
- * (senf::Parse_ListB< IPv6Packet, num_of_fbips>) ); //6
- * This can't work for two reasons:
- * -SENF_PARSER_PRIVATE_VARIANT only accepts 6 templates in types but you have to start from 0.
- * -you NEVER can use templated Parsers in these macros since the macro-preprocessor won't recognize the <> brackets and will
- * interpret the ","
- *
- * The first problem is solved by using (actually inventing) SENF_PARSER_VARIANT_TRANS which has the same limitations
- * concerning the number of types but isn't limited to the values used. This is achieved by a translating function
- * as you can see.
- * The second problem is solved by introducing Helper-Parser which cover both the list and the number field. By that no
- * templates have to be used.
