Detailed Description

GDigitizedData represents the post-digitization view of a hit. It stores the quantities produced after detector-response and electronics logic have transformed simulation truth into readout-oriented observables.

The class is intentionally schema-flexible:

  • scalar values are stored in keyed maps
  • optional array-valued observables can represent richer payloads such as samples or waveforms
  • detector-specific content can be extended without changing the core library ABI

Stored categories:

  • intObservablesMap : integer-valued scalar observables
  • doubleObservablesMap : floating-point scalar observables
  • arrayIntObservablesMap : integer arrays
  • arrayDoubleObservablesMap : floating-point arrays

Identity:

  • the object copies the hit identity from the source GHit
  • the identity is preserved independently of the originating hit lifetime
  • a readable representation is available through getIdentityString()

Event and integration semantics:

Streaming-readout filtering: The conventional keys defined in gdataConventions.h :

  • crate
  • slot
  • channel
  • timeAtElectronics
  • chargeAtElectronics

are treated as streaming-readout identifiers and can be separated from non-SRO observables with:
