Detailed Description

Runtime lookup table that maps trigger values to names and positions.

Built once after the TOML config is loaded. Config-defined triggers occupy the first slots (in declaration order); the built-in defaults follow. This ordering governs histogram bin layout when calling label_axes.

Constructor & Destructor Documentation

trigger_registry()

trigger_registry::trigger_registry ( const std::vector< trigger_config > &  config_triggers )

inlineexplicit

Build the registry from a list of config-defined triggers.

Config triggers are inserted first (preserving TOML declaration order), followed by all entries in all_default_triggers. Duplicate values are not filtered — config entries take priority by appearing first.

Parameters

config_triggers

Triggers parsed from the TOML config file.

Member Function Documentation

index_of()

int trigger_registry::index_of ( uint8_t  trigger_value ) const

inline

Returns the registry position for a given trigger value.

If the value is not found, emits a warning and falls back to the position of _TRIGGER_UNKNOWN_ in the default table.

Parameters

trigger_value

Raw 8-bit trigger value from the data stream.

Returns

Position in triggers.

label_axes()

void trigger_registry::label_axes ( TH2F *  h ) const

inline

Labels both axes of a 2D ROOT histogram with trigger names.

Bin i+1 on both X and Y axes is set to the name of the i-th trigger in the registry. Intended for trigger-vs-trigger correlation plots.

Parameters

h	Pointer to the histogram whose axes will be labelled.

name_of()

std::string trigger_registry::name_of ( uint8_t  trigger_value ) const

inline

Returns the name associated with a trigger value.

Parameters

trigger_value

Raw 8-bit trigger value from the data stream.

Returns

Name string, or "UNKNOWN" if not found.

size()

int trigger_registry::size ( ) const

inline

Returns

Total number of triggers in the registry (config + defaults).
