Detailed Description

template<typename NUMERIC_TYPE, typename SIGNED_TYPE>
class ns3::SequenceNumber< NUMERIC_TYPE, SIGNED_TYPE >

Generic "sequence number" class.

This class can be used to handle sequence numbers. In networking protocols, sequence numbers are fixed precision integer numbers that are used to order events relative to each other. A sequence number is expected to increase over time but, since it has a limited number of bits, the number will "wrap around" from the maximum value that can represented with the given number of bits back to zero. For this reason, comparison of two sequence numbers, and subtraction, is non-trivial. The SequenceNumber class behaves like a number, with the usual arythmetic operators implemented, but knows how to correctly compare and subtract sequence numbers.

This is a templated class. To use it you need to supply two fundamental types as template parameters: NUMERIC_TYPE and SIGNED_TYPE. For instance, SequenceNumber<uint32_t, int32_t> gives you a 32-bit sequence number, while SequenceNumber<uint16_t, int16_t> is a 16-bit one. For your convenience, these are typedef'ed as SequenceNumber32 and SequenceNumber16, respectively.
