class out_of_range; |
Defines a type of object to be thrown as exception. It reports errors that are consequence of attempt to access elements out of defined range.
It may be thrown by the member functions of std::bitset
and std::basic_string
, by std::stoi
and std::stod
families of functions, and by the bounds-checked member access functions (e.g. std::vector::at
and std::map::at
).
Inheritance diagram.
(constructor) | constructs the exception object (public member function) |
explicit out_of_range( const std::string& what_arg ); | (1) | |
explicit out_of_range( const char* what_arg ); | (2) | (since C++11) |
Constructs the exception object with what_arg
as explanatory string that can be accessed through what()
.
Because copying std::out_of_range
is not permitted to throw exceptions, this message is typically stored internally as a separately-allocated reference-counted string. This is also why there is no constructor taking std::string&&
: it would have to copy the content anyway.
what_arg | - | explanatory string |
May throw std::bad_alloc
.
[virtual] | destroys the exception object (virtual public member function of std::exception ) |
[virtual] | returns an explanatory string (virtual public member function of std::exception ) |
The standard error condition std::errc::result_out_of_range
typically indicates the condition where the result, rather than the input, is out of range, and is more closely related to std::range_error
and ERANGE
.
accesses the specified character with bounds checking (public member function of std::basic_string<CharT,Traits,Allocator> ) |
