Detailed Description

If a socket is attached to several ports, each port is identified by a different control code. This control code forms the variable part of the socket encoding and is defined by SocketCodeTable class.

The SocketCodeTable class contains objects that represent port control codes, namely FUPortCode, RFPortCode and IUPortCode. Because a single SocketCodeTable instance is shared by several socket encodings, it is not owned by SocketEncoding objects. Instead, socket code tables are owned by BinaryEncoding class, which provides methods to access and handle them.

Port codes consists of one or two parts: port ID and/or register index. Port IDs are aligned to the left end of the field and register indices to the right end. That is, if port ID + register index do not take all the bits of the width reserved for the table, there are unused bits between port ID and register index.
