Public Functions

template<typename T> inline explicit Varying(const T &value): Generalized constructor for bool, integral- and float-types. This constructor has been specialized for std::string and std::vector<std::byte>.

explicit Varying(const std::vector<std::byte> &value): Constructor for an arbitrary sequence of bytes value.

explicit Varying(const std::string &value): Constructor for a string value.

inline explicit Varying(const char *value): Constructor for a string literal value.

Varying(const Varying &other): Copy constructor.

Varying(Varying &&other) noexcept: Move constructor.

Varying &operator=(const Varying &other): Assignment operator. i.e., type_A = type_B.

Varying &operator=(const std::vector<std::byte> &value): Assigns an arbitrary sequence of bytes value.

Varying &operator=(const std::string &value): Assigns a string value.

template<typename T, std::enable_if_t<IsBool<T>::value, bool> = true> inline Varying &operator=(const T &value): Assigns a bool value.

template<typename T, std::enable_if_t<IsInteger<T>::value, bool> = true> inline Varying &operator=(const T &value): Assigns an integer value.

template<typename T, std::enable_if_t<IsFloat<T>::value, bool> = true> inline Varying &operator=(const T &value): Assign a floating point value.

inline bool operator==(const Varying &that) const: Equality operator.

inline bool operator!=(const Varying &that) const: Inequality operator.

inline bool operator>(const Varying &that) const: Relation operators.

inline bool operator>=(const Varying &that) const: Relation operators.

template<typename T> inline UnsignedIntegerType<T> GetValue() const: Returns an unsigned integer if able.

template<typename T> inline UserDataType<T> GetValue() const: Returns user data if able.

std::string GetStringValue() const: Returns the string value if valid. Otherwise throws std::logic_error.

bool GetBoolValue() const: Returns the bool value if valid. Otherwise throws std::logic_error.

int64_t GetIntegerValue() const: Returns the integer value if valid. Otherwise throws std::logic_error.

double GetFloatValue() const: Returns the float value if valid. Otherwise throws std::logic_error.
