Typedef Documentation

typedef AbstractValue<DataBase, RawData> Protocols::Generics::Data

Protocol data exchanged between parties. Data encapsulates a logical (in regard to a communication protocol) piece of data that communicating parties could exchange. The concrete protocol data object will be an instance of a class derived from DataBase. A DataBase reference to the encapsulated object is returned by object(). This reference could be casted to access the data fields of the object. Definition at line 41 of file Data.h.

typedef AbstractValue<PacketBase, BadPacket, DataBase> Protocols::Generics::Packet

PacketBase Value Object wrapper. Check the docs of AbstractValue for a description of the underlying concept. Todo: There was the idea to define Packet for each protocol. The problem was that that would require each protocol to also define a BadPacket or NullPacket class. If the one from Generics (i.e. here) is used, then there might be a problem at runtime - casting BadPacket which is derived from Generics::PacketBase to DataBase (that's fine) and then casing is to e.g. BitTorrent::Packets::PacketBase, which is unrelated to BadPacket! How to solve that? Definition at line 45 of file Packet.h.
