Searching for PDF data

Search path handling functions
std::vector< std::string >	LHAPDF::paths ()
	Get the ordered list of search paths, from $LHAPDF_DATA_PATH and the install location.
void	LHAPDF::setPaths (const std::string &pathstr)
	Set the search paths list as a colon-separated string.
void	LHAPDF::setPaths (std::vector< string > paths)
	Set the search paths list.
void	LHAPDF::pathsPrepend (const std::string &p)
	Prepend to the search paths list.
void	LHAPDF::pathsAppend (const std::string &p)
	Append to the search paths list.
std::string	LHAPDF::findFile (const std::string &target)
std::vector< std::string >	LHAPDF::findFiles (const std::string &target)
	Return all locations in which a file is found.

PDF-specific path functions
std::string	LHAPDF::pdfmempath (const std::string &setname, int member)
	Build the form of a PDF member-data file path relative to the search dir.
std::string	LHAPDF::findpdfmempath (const std::string &setname, int member)
	Find a PDF member-data file path in the search paths.
std::string	LHAPDF::pdfsetinfopath (const std::string &setname)
	Build the form of a PDF info file path relative to the search dir.
std::string	LHAPDF::findpdfsetinfopath (const std::string &setname)
	Find a PDF info file path in the search paths.
const std::vector< std::string > &	LHAPDF::availablePDFSets ()
	Get the names of all available PDF sets in the search path.

Detailed Description

Function Documentation

availablePDFSets()

const std::vector< std::string > & LHAPDF::availablePDFSets

(

)

Get the names of all available PDF sets in the search path.

Note

Taken from scanning the directories in the search path (i.e. LHAPDF_DATA_PATH) for viable PDF sets.

The result is cached when first called, to avoid repeated filesystem walking. It's assumed that new PDFs will not appear on the filesystem during a run: please let the authors know if that's not a good assumption!

Examples

/tests/testinfo.cc, and /tests/testpaths.cc.

findFile()

std::string LHAPDF::findFile

(

const std::string &

target

)

Return the first location in which a file is found

If no matching file is found, return an empty path.

Examples

/tests/testpaths.cc.

findpdfsetinfopath()

std::string LHAPDF::findpdfsetinfopath ( const std::string & setname )

inline

Find a PDF info file path in the search paths.

Todo

Check that set info and mem=0 file are in same dir?

paths()

std::vector< std::string > LHAPDF::paths

(

)

Get the ordered list of search paths, from $LHAPDF_DATA_PATH and the install location.

Note

The install prefix will be appended unless $LHAPDF_DATA_PATH ends with a double colon, i.e. '::'

Examples

/tests/testgrid.cc, and /tests/testpaths.cc.
