◆ keysIn()

std::vector< std::string > o2::framework::NativeAODInputFile::keysIn ( std::string const &  dir)
overridevirtual

Names of the keys inside the top-level directory dir, empty if there is none.

◆ monitoringDetails()

std::string o2::framework::NativeAODInputFile::monitoringDetails ( ) const
overridevirtual

Extra key=value pairs for the file monitoring metrics, starting with a comma.

Reimplemented from o2::framework::AODInputFile.

Definition at line 361 of file NativeAOD.cxx.

◆ name()

std::string o2::framework::NativeAODInputFile::name ( ) const
inlineoverridevirtual

◆ open() [1/2]

std::shared_ptr< NativeAODInputFile > o2::framework::NativeAODInputFile::open ( std::string const &  url,
RootObjectReadingFactory &  factory,
o2::aod::native::Options const &  options,
std::string const &  name = {} 
)
static

Opens url and parses its header, keys, maps and the trees of its first DF, so that layouts and versions we cannot read are found here, when the file can still go to ROOT. Throws o2::aod::native::FormatError. name is what the file is called (an LFN for a grid file); url by default.

Definition at line 328 of file NativeAOD.cxx.
