/C++std::length_error
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.
Inheritance diagram.
Member functions
| (constructor) | constructs the exception object (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
|
[virtual] | destroys the exception object (virtual public member function of std::exception) |
|
[virtual] | returns an explanatory string (virtual public member function of std::exception) |
