std::length_error: std::length_error

NAME

std::length_error - std::length_error

Synopsis


Defined in header <stdexcept>
class length_error;


Defines a type of object to be thrown as exception. It reports errors that result from attempts to exceed implementation defined length limits for some object.
This exception is thrown by member functions of std::basic_string and std::vector::reserve

Member functions


              constructs the exception object
constructor (public member function)


 std::length_error::length_error


explicit length_error( const std::string& what_arg ); (1)
explicit length_error( 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::length_error 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.

Parameters


what_arg - explanatory string

Exceptions


May throw std::bad_alloc


Inherited from std::exception

Member functions


destructor destroys the exception object
             (virtual public member function of std::exception)
[virtual]


what returns an explanatory string
             (virtual public member function of std::exception)
[virtual]
