Detailed Description

Utilities for use in an environment without art.

Function Documentation

fhicl::ParameterSet lar::standalone::ParseConfiguration ( std::string  configPath, cet::filepath_maker &  lookupPolicy  )

inline

Parses a FHiCL configuration file.

Parameters

configPath	the path to the configuration file to be parsed
lookupPolicy	class performing the proper lookup for FHiCL files

Returns

a parameter set containing the whole configuration from the file

Some lookup policies are provided in cetlib (see cetlib/filepath_maker.h file).

Definition at line 106 of file StandaloneBasicSetup.h.

{
  fhicl::ParameterSet pset;
  pset = fhicl::ParameterSet::make(configPath, lookupPolicy);
  return pset;
} // ParseConfiguration(string, filepath_maker)

fhicl::ParameterSet lar::standalone::ParseConfiguration ( std::string  configPath )

inline

Parses a FHiCL configuration file.

Parameters

configPath

the path to the configuration file to be parsed

Returns

a parameter set containing the whole configuration from the file

The lookup policy for finding the FHiCL files is such that:

• configPath must be readily available: no special lookup is performed
• FHiCL files included (directly or indirectly) by configPath are searched for in the path list specified in the environment variable FHICL_FILE_PATH

Definition at line 116 of file StandaloneBasicSetup.h.

{
  cet::filepath_lookup_after1 policy("FHICL_FILE_PATH");
  return ParseConfiguration(configPath, policy);
} // ParseConfiguration(string)

void lar::standalone::SetupMessageFacility ( fhicl::ParameterSet const &  pset, std::string  applName = "standalone"  )

inline

Sets up the message facility service.

Parameters

pset	global configuration parameter set
applName	(default: "standalone") name of running the application

The configuration is read from the path services.message (as for the standard art behaviour). Any configuration working in art is expected to work here as well.

Technical details:

• "context singlet" is set to main (mf::SetContextSinglet())
• "context iteration" is set to empty (mf::SetContextIteration())

Definition at line 125 of file StandaloneBasicSetup.h.

{
  mf::StartMessageFacility(pset.get<fhicl::ParameterSet>("services.message"));
  mf::SetApplicationName(applName);
  mf::SetContextSinglet("main");
  mf::SetContextIteration("");
} // lar::standalone::SetupMessageFacility()
