Detailed Description

The brio generic reader class.

Constructor & Destructor Documentation

◆ reader() [1/3]

brio::reader::reader ( )

Default constructor.

◆ reader() [2/3]

brio::reader::reader	(	const std::string &	filename_,
		datatools::logger::priority	p_ = `datatools::logger::PRIO_FATAL`
	)

Constructor.

◆ reader() [3/3]

brio::reader::reader	(	const std::string &	filename_,
		const std::string &	format_str_,
		datatools::logger::priority	p_ = `datatools::logger::PRIO_FATAL`
	)

Constructor.

◆ ~reader()

virtual brio::reader::~reader ( )

virtual

Destructor.

Member Function Documentation

◆ _at_load()

template<class T >

int brio::reader::_at_load	(	T &	data_,
		store_info *	ptr_si_,
		int64_t	nentry_
	)

protected

◆ _at_open()

virtual void brio::reader::_at_open ( const std::string & filename_ )

protectedvirtual

Implements brio::detail::base_io.

◆ _set_default()

void brio::reader::_set_default ( )

protected

◆ has_next()

bool brio::reader::has_next ( const std::string & label_ = "" ) const

Check if some next entry exists relatively to the current entry

◆ has_previous()

bool brio::reader::has_previous ( const std::string & label_ = "" ) const

Check if some previous entry exists relatively to the current entry

◆ is_check_serial_tag()

bool brio::reader::is_check_serial_tag ( ) const

◆ load() [1/2]

template<typename T >

int brio::reader::load	(	T &	data_,
		int64_t	nentry_ = `-1`
	)

Load template method for arbitrary entry.

◆ load() [2/2]

template<typename T >

int brio::reader::load	(	T &	data_,
		const std::string &	label_,
		int64_t	nentry_ = `-1`
	)

Load template method for arbitrary store and entry.

◆ load_next()

template<typename T >

int brio::reader::load_next	(	T &	data_,
		const std::string &	label_ = `""`
	)

Load template method for next entry.

◆ load_previous()

template<typename T >

int brio::reader::load_previous	(	T &	data_,
		const std::string &	label_ = `""`
	)

Load template method for previous entry.

◆ print_info()

void brio::reader::print_info ( std::ostream & out_ = std::clog ) const

Print.

◆ rewind_store()

void brio::reader::rewind_store ( const std::string & label_ = "" )

Position current entry of store 'label' just before the first serialized object

◆ set_check_serial_tag()

void brio::reader::set_check_serial_tag ( bool new_value_ = true )

By default, serialization tag are checked each time an object is deserialized. This behaviour can be changed:

brio::reader a_reader; a_reader.open("file.root"); a_reader.set_check_serial_tag(false);

◆ tree_dump()

virtual void brio::reader::tree_dump	(	std::ostream &	out_ = `std::clog`,
		const std::string &	title_ = `""`,
		const std::string &	indent_ = `""`,
		bool	inherit_ = `false`
	)		const

virtual

Smart print.

Reimplemented from brio::detail::base_io.

◆ unwind_store()

void brio::reader::unwind_store ( const std::string & label_ = "" )

Position current entry of store 'label' just after the last serialized object
