Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 123]

▼NFMI
▼NComm
CChannel	Interface that defines channel operations. Only provides a few default implementations, the rest is implemented in the specific ClientServer or PeerToPeer channel types
CClientServer	Client-Server channel type
CData	Small data wrapper around a generic type T with some helper utilities
CData< std::vector< A > >	Wrapper around an arbitrary STL vector
CData< void * >	Instantiate data with a pointer to memory and an arbitrary size. Should only be used in exceptional cases, the native types should be used otherwise
CDirect	Channel that uses the TCPunch TCP NAT Hole Punching Library for connection establishment
CPeerToPeer	Peer-To-Peer channel type
CRedis	Channel that uses Redis with the Hiredis client library as storage backend
CS3	Channel that uses AWS S3 as backend and uses the AWS SDK for C++ to access S3
▼NUtils	Contains various utilities that are used in FMI
CChannelPolicy	Default channel policy that either selects the fastest or cheapest channel according to the performance model, based on the currently set hint
CConfiguration	Configuration parser for the FMI JSON configuration file
CFunction	Small wrapper around an arbitrary C++ binary function with signature T(T,T), i.e. accepting two arguments of type T and returning one of type T
COperationInfo	All the information about an operation, passed to the Channel Policy for its decision on which channel to use
CTimeout	Custom exception that is thrown on timeouts
CCommunicator	Interface that is exposed to the user for interaction with the FMI system
Cchannel_data	Data that is passed to and from channels
Craw_function	Struct with functions that is passed to channels, additionally contains information on associativitiy / commutativity (provided by the user)
