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

[detail level 123]

artdaq
coredemo	Namespace used to differentiate the artdaq_core_demo version of GetPackageBuildInfo from other versions present in the system
GetPackageBuildInfo	Wrapper around the coredemo::GetPackageBuildInfo::getPackageBuildInfo function
demo	The artdaq_demo namespace
detail	Implementation details namespace
AsciiFragment	An artdaq::Fragment overlay class designed to hold string data for pedagogical purposes
Header	The AsciiFragment::Header contains information about the payload size and the "line number" of the data contained in the AsciiFragment
Metadata	Metadata describing the contents of the AsciiFragment
AsciiFragmentWriter	Class derived from AsciiFragment which allows writes to the data (for simulation purposes)
ToyFragment	An artdaq::Fragment overlay class used for pedagogical purposes
Header	The "Header" struct is used to interpret the header information that is created by the hardware and is part of the data blob that is read from the hardware for each event. Not to be confused with the Fragment::Header or the ToyFragment::Metadata objects
Metadata	The ToyFragment::Metadata struct holds data about the readout that may not be present in the primary data stream
UDPFragment	A Fragment designed to contain data received from the network in UDP datagrams
Header	The UDPFragment::Header contains information about the payload size and the "data type" of the UDP data
Metadata	Metadata describing the contents of the UDPFragment
UDPFragmentWriter	Class derived from UDPFragment which allows writes to the data
