Value

struct Value

Represents a value that can be one of the following five types:

• integer (int64_t).

• floating-point value (double).

• boolean (bool).

• string (std::string).

• empty

It is possible to convert a C++ value to a Value instance and back to a C++ value.

Value also overloads several operators such as addition and multiplication.

Public Functions

inline bool is_empty() const

Returns true if this Value is empty.

inline bool is_integer() const

Returns true if this Value is an integer.

inline bool is_string() const

Returns true if this Value is a string.

inline bool is_bool() const

Returns true if this Value is a boolean.

inline bool is_double() const

Returns true if this Value is a floating-point number.

integer_type to_integer() const

std::string to_string() const

Convert this value to a string.

bool to_bool() const

Convert this value to a bool.

double to_double() const

Convert this value to a double.

float to_float() const

Convert this value to a float.

TemplateArg to_template_arg() const

Convert this value to a TemplateArg.

template<typename T>
inline bool is() const

Returns true if this value is convertible to an instance of T.

template<typename T>
inline T to() const

Convert this Value to an instance of type T if this is possible.
