Data Structures

Here are the data structures with brief descriptions:

CGAncestorData	Initial state of one hit-producing track or one of its ancestors
CGDataCollection	Per-sensitive-detector container that owns truth and digitized data objects
CGDigitizedData	Stores digitized, electronics-level observables for one hit
CGEventDataCollection	Owns all detector-local data for one event
CGEventHeader	Stores minimal metadata for one event
CGFrameDataCollection	Owns one frame header and the list of payloads accumulated for that frame
CGFrameHeader	Stores minimal metadata for one frame-style time window
CGGeneratedParticleData	Serialization record for one generated particle in event output
CGIntegralPayload	Stores one integrated readout payload sample
CGRunDataCollection	Owns and updates the run-level detector summary map
CGRunHeader	Stores minimal run metadata and run-level event counters
CGTrueInfoData	Stores simulation-level observables for one hit
