struct BadOptionalAccess : public std::exception

Defines a type of object to be thrown by TRAP::Optional::Value() when accessing an optional object that does not contain a value.

Public Functions

BadOptionalAccess() noexcept = default

Constructs a new BadOptionalAccess object with an implementation-defined null-terminated byte string which is accessible through what().

Default constructor.

constexpr BadOptionalAccess(const BadOptionalAccess &other) noexcept = default

Constructs a new BadOptionalAccess object with an implementation-defined null-terminated byte string which is accessible through what().

Copy constructor. If *this and other both have dynamic type TRAP::BadOptionalAccess then std::strcmp(what(), other.what()) == 0.

Parameters:

other – Another exception object to copy.

BadOptionalAccess &operator=(const BadOptionalAccess &other) noexcept = default

Assigns the contents with those of other. If *this and other both have dynamic type TRAP::BadOptionalAccess then std::strcmp(what(), other.what()) == 0 after assignment.

Parameters:

other – Another exception object to assign with.

Returns:

*this.

inline constexpr const char *what() const noexcept override

Returns the explanatory string.

Returns:

Pointer to a null-terminated string with explanatory information. The string is suitable for conversion and display as a std::wstring. The pointer is guaranteed to be valid at least until the exception object from which it is obtained is destroyed, or until a non-const member function (e.g. copy assignment operator) on the exception object is called.
