Detailed Description

Metadata class for PDF members.

Constructor & Destructor Documentation

PDFInfo() [1/2]

LHAPDF::PDFInfo::PDFInfo ( )

inline

Default constructor (for container compatibility)

Note

Don't use explicitly!

Todo

Remove/delete?

PDFInfo() [2/2]

LHAPDF::PDFInfo::PDFInfo

(

const std::string &

mempath

)

Constructor from a PDF member's data path.

Todo

Bypasses standard path searching hence used by the path-based GridPDF constructor, for example.

Member Function Documentation

get_entry() [1/2]

const std::string & LHAPDF::PDFInfo::get_entry ( const std::string & key ) const

virtual
