◆ initialize()

void marlinmt::StdHepFileSource::initialize ( )

overridevirtual

Init data source.

Reimplemented from marlinmt::DataSourcePlugin.

Definition at line 66 of file StdHepFileSource.cc.

References _fileName, _fileReader, marlinmt::ParameterBase< T >::get(), and marlinmt::DataSourcePlugin::initialize().

◆ readOne()

bool marlinmt::StdHepFileSource::readOne ( )

overridevirtual

Read one record from the input stream.

Users must call processRunHeader() or processEvent() to forward it to the framework. Returns true on success. If the end of the stream is reached, return false.
