Public Member Functions
	MilleData (bool doublePrecision=false, bool absFilePaths=false)
	Constructor. Set doublePrecision to true to write binary files with doubles instead of floats.
virtual	~MilleData ()
	Destructor.
virtual void	merge (const MergeableNamed *other) override
	Implementation of merging.
virtual void	clear () override
	Implementation of clearing.
void	open (std::string filename)
	Open a new file and remember it. Filename should encode also process id!
bool	isOpen ()
	Is some file already open?
void	fill (gbl::GblTrajectory &trajectory)
	Write a GBL trajectory to the binary file.
void	close ()
	Close current mille binary if opened.
const std::vector< std::string > &	getFiles () const
	Get the list of all created files.
MilleData &	operator= (const MilleData &other)
	Copy by assignment (if some file on LHS is opened, it is closed during this operation; file pointers not transferred - new file to be opened)
	MilleData (const MilleData &other)
	Construct from other object (pointer to binary file is not transferred - new file has to be opened by new object)
virtual MilleData *	Clone (const char *newname="") const override
	Clone object (with optionally a new name)
int	getNumRecords ()
	Get number of records (trajectories) written to binary files.
bool	hasDoublePrecision ()
	Are files written with double precision?
void	addFile (const std::string &path)
	Add a filename (path) to the file list manually.
virtual Long64_t	Merge (TCollection *hlist)
	Allow merging using TFileMerger if saved directly to a file.
virtual void	Reset ()
	Root-like Reset function for "template compatibility" with ROOT objects. More...
virtual void	SetDirectory (TDirectory *)
	Root-like Clone function for "template compatibility" with ROOT objects. More...

Private Member Functions
	ClassDef (MergeableNamed, 0)
	Abstract base class for objects that can be merged and named.

Private Attributes
bool	m_doublePrecision {false}
	Use double-precision for binary files.
bool	m_absFilePaths {false}
	Use absolute file paths to binary files Default is False - so you have to move the binaries to working dir of the algorithm If True, the original location of binaries is remembered in datastore and Millepede will take them from there.
std::vector< std::string >	m_files {}
	List of already created file names.
gbl::MilleBinary *	m_binary {nullptr}
	Pointer to current binary file.
int	m_numRecords {0}
	Pointer to opened binary file (not streamed) More...
