Detailed Description

Function Documentation

◆ lookupLHAPDFID()

int LHAPDF::lookupLHAPDFID ( const std::string &  setname,
int  nmem 
)

Look up the member's LHAPDF index from the set name and member ID.

If lookup fails, -1 is returned, otherwise the LHAPDF ID code. NB. This function is relatively slow, since it requires std::map reverse lookup.

◆ lookupPDF() [1/2]

std::pair<std::string, int> LHAPDF::lookupPDF ( int  lhaid)

Look up a PDF set name and member ID by the LHAPDF ID code

The set name and member ID are returned as an std::pair. If lookup fails, a pair ("", -1) is returned.

Examples:
/tests/testindex.cc.

◆ lookupPDF() [2/2]

std::pair<std::string, int> LHAPDF::lookupPDF ( const std::string &  pdfstr)

Decode a single PDF member ID string into a setname,memid pair.

Note
A trivial <SET,MEM> decoding rather than a "real lookup", for convenience & uniformity.
