Public Types

Public Member Functions
constexpr	version (version_element major=0, version_element minor=0) noexcept
	Initialize an instance with the given major and minor version info.
constexpr bool	empty () const noexcept
	Check if this version is an "empty" value – meaning major and minor are both 0.
constexpr	operator std::uint64_t () const
	Convert this instance into a uint64_t.
constexpr bool	operator== (const version &other) const
	Test for equality with other.
constexpr bool	operator!= (const version &other) const
	Test for inequality with other.
constexpr bool	operator< (const version &other) const
	Check that this version is less than other. The comparison is done lexicographically.
constexpr bool	operator<= (const version &other) const
	Check that this version is less than or equal to other. The comparison is done lexicographically.
constexpr bool	operator> (const version &other) const
	Check that this version is greater than other. The comparison is done lexicographically.
constexpr bool	operator>= (const version &other) const
	Check that this version is greater than or equal to other. The comparison is done lexicographically.

Detailed Description

Represents a version used to extract and encode JSON objects from C++ classes.

This is useful for API versioning: if you need certain fields to be serialized only after a certain version or only before a different one.

Constructor & Destructor Documentation

version()

constexpr jsonv::version::version ( version_element  major = 0, version_element  minor = 0  )

inlineconstexprnoexcept

Initialize an instance with the given major and minor version info.

Definition at line 30 of file version.hpp.

Member Function Documentation

empty()

constexpr bool jsonv::version::empty ( ) const

inlineconstexprnoexcept

Check if this version is an "empty" value – meaning major and minor are both 0.

Definition at line 36 of file version.hpp.

operator std::uint64_t()

constexpr jsonv::version::operator std::uint64_t ( ) const

inlineexplicitconstexpr

Convert this instance into a uint64_t.

The major version will be in the higher-order bits, while minor will be in the lower-order bits.

Definition at line 43 of file version.hpp.

operator!=()

constexpr bool jsonv::version::operator!= ( const version &  other ) const

inlineconstexpr

Test for inequality with other.

Definition at line 56 of file version.hpp.

operator<()

constexpr bool jsonv::version::operator< ( const version &  other ) const

inlineconstexpr

Check that this version is less than other. The comparison is done lexicographically.

Definition at line 62 of file version.hpp.

operator<=()

constexpr bool jsonv::version::operator<= ( const version &  other ) const

inlineconstexpr

Check that this version is less than or equal to other. The comparison is done lexicographically.

Definition at line 68 of file version.hpp.

operator==()

constexpr bool jsonv::version::operator== ( const version &  other ) const

inlineconstexpr

Test for equality with other.

Definition at line 50 of file version.hpp.

operator>()

constexpr bool jsonv::version::operator> ( const version &  other ) const

inlineconstexpr

Check that this version is greater than other. The comparison is done lexicographically.

Definition at line 74 of file version.hpp.

operator>=()

constexpr bool jsonv::version::operator>= ( const version &  other ) const

inlineconstexpr

Check that this version is greater than or equal to other. The comparison is done lexicographically.
