std::logic_error: std::logic_error

NAME

std::logic_error - std::logic_error

Synopsis


Defined in header <stdexcept>
class logic_error;


Defines a type of object to be thrown as exception. It reports errors that are a consequence of faulty logic within the program such as violating logical preconditions or class invariants and may be preventable.
No standard library components throw this exception directly, but the exception types std::invalid_argument, std::domain_error, std::length_error, std::out_of_range, std::future_error, and std::experimental::bad_optional_access are derived from std::logic_error.

Member functions


              constructs the exception object
constructor (public member function)


 std::logic_error::logic_error


explicit logic_error( const std::string& what_arg ); (1)
explicit logic_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::logic_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

May throw std::bad_alloc


Inherited from std::exception
