Member Function Documentation

fhicl::ParameterSet icarus::TriggerConfigurationExtractorBase::convertConfigurationDocuments ( fhicl::ParameterSet const &  container, std::string const &  configListKey, std::initializer_list< std::regex const >  components  )

static

Returns a parameter set with the content of configuration_documents key from container.

Parameters

container	parameter set including a table with key configListKey
configListKey	name of the key in container with the configuration
components	keys to be converted (as regular expressions)

Returns

a parameter set

The configuration_documents element of container is processed: for each of its keys which match at least one of the components regular expression patterns (std::regex_match()), the associated string value is parsed with FHiCL parser, and the result is set as a FHiCL table in the output parameter set. For example, if the components are { std::regex{".*pmt.*"}, std::regex{".*trigger.*"} }, the returned value is a parameter set that may have keys like icaruspmtee01, icaruspmtew02, icarustrigger etc., each one with a FHiCL table as `value.

ConfigurationData_t icarus::TriggerConfigurationExtractorBase::extract

(

fhicl::ParameterSet const &

config

)

const

Extracts all supported Trigger configuration from config.

Parameters

config

a FHiCL parameter set with component configuration

Returns

an object with the supported Trigger configuration

All Trigger-related configuration that is known to this code is extracted and returned.

This function is undefined here: it must be overridden.

template<typename RBegin , typename REnd >

bool icarus::TriggerConfigurationExtractorBase::matchKey ( std::string const &  key, RBegin  rbegin, REnd  rend  )

static

Returns whether key matches at least one of the regular expressions in the [ rbegin, rend [ range.

Definition at line 455 of file TriggerConfigurationExtractor.h.

{
  for (auto iRegex = rbegin; iRegex != rend; ++iRegex)
    if (std::regex_match(key, *iRegex)) return true;
  return false;
} // icarus::PMTconfigurationExtractorBase::matchKey()

static bool icarus::TriggerConfigurationExtractorBase::mayHaveConfiguration ( fhicl::ParameterSet const &  pset )

inlinestatic

Returns whether pset may contain the needed configuration.
