Detailed Description

A GTouchable acts as a compact “address” for sensitive detector elements during hit processing and digitization. It is commonly used as a key when deciding whether a newly produced hit should:

merge into an existing hit collection entry, or
create a new entry.

Comparison semantics

The equality operator implements a two-stage comparison:

Compare the identity vector values positionally (same size and same identifier values).
If identities match, apply a type-specific discriminator:
- readout compares stepTimeAtElectronicsIndex
- flux compares trackId
- dosimeter compares trackId
- particleCounter always matches once identities match

The identity vector size mismatch is considered an exceptional situation and is logged at debug level.

Constructor & Destructor Documentation

◆ GTouchable() [1/4]

GTouchable::GTouchable ( const GTouchable & )

default

◆ GTouchable() [2/4]

GTouchable::GTouchable	(	const std::shared_ptr< GOptions > &	gopt,
		const std::string &	digitization,
		const std::string &	gidentityString,
		const std::vector< double > &	dimensions )

This constructor is used when a module options object is available and a module-scoped logger should be created/used by the base class.

Called from detector construction code when building the sensitive detector registry.

Parameters

gopt	Options container used to configure logging and module behavior.
digitization	Digitization type string (e.g. `"readout"`, `FLUXNAME`, `COUNTERNAME`).
gidentityString	Identity specification string, e.g. `"sector: 2, layer: 4, wire: 33"`.
dimensions	Physical dimensions of the detector element (module-defined convention).

Definition at line 16 of file gtouchable.cc.

◆ GTouchable() [3/4]

GTouchable::GTouchable	(	const std::shared_ptr< GLogger > &	logger,
		const std::string &	digitization,
		const std::string &	gidentityString,
		const std::vector< double > &	dimensions )

This constructor is useful when a caller already owns a configured logger instance (for example in tests or in code that wants to share a logger across multiple objects).

Parameters

logger	Logger instance used for diagnostics.
digitization	Digitization type string (e.g. `"readout"`, `FLUXNAME`, `COUNTERNAME`).
gidentityString	Identity specification string, e.g. `"sector: 2, layer: 4, wire: 33"`.
dimensions	Physical dimensions of the detector element (module-defined convention).

Definition at line 52 of file gtouchable.cc.

◆ GTouchable() [4/4]

GTouchable::GTouchable	(	const std::shared_ptr< GTouchable > &	base,
		int	newTimeIndex )

inline

This is used to create a new hit key when the identity matches but the time-cell differs, i.e. when a hit must be split by electronics time window.

The copy uses the base class copy constructor and then copies the data members from base, replacing only stepTimeAtElectronicsIndex with newTimeIndex.

Parameters

base	Existing touchable to copy from.
newTimeIndex	The updated electronics time-cell index.

Definition at line 191 of file gtouchable.h.

◆ ~GTouchable()

GTouchable::~GTouchable ( )

inline

The destructor logs the type and getIdentityString() at debug level, which can be useful when diagnosing object lifetimes.

Definition at line 207 of file gtouchable.h.

Member Function Documentation

◆ assignStepTimeAtElectronicsIndex()

void GTouchable::assignStepTimeAtElectronicsIndex ( int timeIndex )

inline

Parameters

timeIndex Electronics time-cell index that represents the readout time window.

Definition at line 241 of file gtouchable.h.

◆ assignTrackId()

void GTouchable::assignTrackId ( int tid )

inline

This value is typically set during hit processing when the simulation step is known.

Parameters

tid	Track id to store in the touchable.

◆ create() [1/2]

static std::shared_ptr< GTouchable > GTouchable::create ( const std::shared_ptr< GLogger > & logger )

inlinestatic

The generated identity uses a deterministic pattern based on a process-wide atomic counter:

sector cycles in [1..6]
paddle cycles in [1..20]

Parameters

logger Logger instance used for diagnostics.

Returns: A newly created test touchable.

Definition at line 331 of file gtouchable.h.

◆ create() [2/2]

static std::shared_ptr< GTouchable > GTouchable::create ( const std::shared_ptr< GOptions > & gopt )

inlinestatic

The generated identity uses a deterministic pattern based on a process-wide atomic counter:

sector cycles in [1..6]
paddle cycles in [1..20]

Parameters

gopt	Options container used to configure logging and module behavior.

Returns: A newly created test touchable.

Definition at line 311 of file gtouchable.h.

◆ exists_in_vector()

bool GTouchable::exists_in_vector ( const std::vector< GTouchable > & v ) const

inline

This is a convenience helper mainly used for diagnostics and validation logic. It logs level-2 informational messages indicating whether the touchable was found.

Parameters

v	Vector of touchables to scan.

Returns: True if a matching touchable is found, false otherwise.

Definition at line 289 of file gtouchable.h.

◆ getDetectorDimensions()

std::vector< double > GTouchable::getDetectorDimensions ( ) const

inline

Dimensions are stored verbatim and interpreted by module-specific digitization logic.

Returns: A vector containing the dimensions.

Definition at line 278 of file gtouchable.h.

◆ getEnergyMultiplier()

double GTouchable::getEnergyMultiplier ( ) const

inline

The multiplier is typically set by digitization logic (for example when distributing energy across multiple readout cells). The default is 1.

Returns: The energy multiplier.

Definition at line 234 of file gtouchable.h.

◆ getIdentity()

std::vector< GIdentifier > GTouchable::getIdentity ( ) const

inline

Returns: The identity vector as a std::vector of GIdentifier.

Definition at line 255 of file gtouchable.h.

◆ getIdentityString()

std::string GTouchable::getIdentityString ( ) const

inline

The returned string is constructed by concatenating each identifier as: "<name>: <value> " (note the trailing space).

Returns: A human-readable identity string.

Definition at line 265 of file gtouchable.h.

◆ getStepTimeAtElectronicsIndex()

int GTouchable::getStepTimeAtElectronicsIndex ( ) const

inline

Returns: The stored time-cell index, or GTOUCHABLEUNSETTIMEINDEX if not assigned yet.

Definition at line 248 of file gtouchable.h.

◆ operator=()

GTouchable & GTouchable::operator= ( const GTouchable & )

default

◆ operator==()

bool GTouchable::operator== ( const GTouchable & gtouchable ) const

Parameters

gtouchable The touchable to compare with.

Returns: True if the objects are considered equal (same identity and same type-specific discriminator).
