Detailed Description

A TableEntry stores the value of a table entry. It can either be of type int, unsigned int, std::uint64_t, double or std::string. In essence, this structure is the same as std::variant<int,unsigned int,std::uint64_t,double,std::string> but we wrap this object in a structure for which we can write a function that can serialize it. This is also why the function is not in fact of type std::any.

value_type

using internal::TableEntry::value_type = std_cxx17::variant<int, unsigned int, std::uint64_t, double, std::string>

private

Abbreviation for the data type stored by this object.

Constructor & Destructor Documentation

TableEntry() [1/2]

internal::TableEntry::TableEntry ( )

default

Default constructor.

TableEntry() [2/2]

template<typename T >

internal::TableEntry::TableEntry

(

const T &

t

)

Constructor. Initialize this table element with the value t.

Member Function Documentation

get()

template<typename T >

T internal::TableEntry::get

Return the value stored by this object. The template type T must be one of int,unsigned int,std::uint64_t,double,std::string and it must match the data type of the object originally stored in this TableEntry object.

Definition at line 817 of file table_handler.h.

get_numeric_value()

double internal::TableEntry::get_numeric_value

(

)

const

Return the numeric value of this object if data has been stored in it either as an integer, an unsigned integer,std::uint64_t, or a double.

Returns

double

Definition at line 35 of file table_handler.cc.

cache_string()

void internal::TableEntry::cache_string	(	bool	scientific,
		unsigned int	precision
	)		const

Cache the contained value with the given formatting and return it. The given parameters from the column definition are used for the formatting. The value is cached as a string internally in cached_value. The cache needs to be invalidated with this routine if the formatting of the column changes.

Definition at line 83 of file table_handler.cc.

get_cached_string()

const std::string & internal::TableEntry::get_cached_string

(

)

const

Return the value cached using cache_string(). This is just a wrapper around cached_value.

Definition at line 106 of file table_handler.cc.

get_default_constructed_copy()

TableEntry internal::TableEntry::get_default_constructed_copy

(

)

const

Return a TableEntry object that has the same data type of the stored value but with a value that is default constructed for this data type. This is used to pad columns below previously set ones.

Definition at line 130 of file table_handler.cc.

save()

template<class Archive >

void internal::TableEntry::save	(	Archive &	ar,
		const unsigned int	version
	)		const

Write the data of this object to a stream for the purpose of serialization using the BOOST serialization library.

Definition at line 842 of file table_handler.h.

load()

template<class Archive >

void internal::TableEntry::load	(	Archive &	ar,
		const unsigned int	version
	)

Read the data of this object from a stream for the purpose of serialization using the BOOST serialization library.

Definition at line 885 of file table_handler.h.

serialize()

template<class Archive >

void internal::TableEntry::serialize	(	Archive &	archive,
		const unsigned int	version
	)

Write and read the data of this object from a stream for the purpose of serialization using the BOOST serialization library.
