class error_code : public error_code #

#include <error_code.hpp>

A hpx::error_code represents an arbitrary error condition.

The class hpx::error_code describes an object used to hold error code values, such as those originating from the operating system or other low-level application program interfaces.

Note

Class hpx::error_code is an adjunct to error reporting by exception

Public Functions

inline explicit error_code(throwmode mode = throwmode::plain)#

Construct an object of type error_code.

Parameters: mode – The parameter mode specifies whether the constructed hpx::error_code belongs to the error category hpx_category (if mode is plain, this is the default) or to the category hpx_category_rethrow (if mode is rethrow).
Throws: nothing –

explicit error_code(error e, throwmode mode = throwmode::plain)#

Construct an object of type error_code.

Parameters

e – The parameter e holds the hpx::error code the new exception should encapsulate.
mode – The parameter mode specifies whether the constructed hpx::error_code belongs to the error category hpx_category (if mode is plain, this is the default) or to the category hpx_category_rethrow (if mode is rethrow).

Throws

nothing –

error_code(error e, char const *func, char const *file, long line, throwmode mode = throwmode::plain)#

Construct an object of type error_code.

Parameters

e – The parameter e holds the hpx::error code the new exception should encapsulate.
func – The name of the function where the error was raised.
file – The file name of the code where the error was raised.
line – The line number of the code line where the error was raised.
mode – The parameter mode specifies whether the constructed hpx::error_code belongs to the error category hpx_category (if mode is plain, this is the default) or to the category hpx_category_rethrow (if mode is rethrow).

Throws

nothing –

error_code(error e, char const *msg, throwmode mode = throwmode::plain)#

Construct an object of type error_code.

Parameters

e – The parameter e holds the hpx::error code the new exception should encapsulate.
msg – The parameter msg holds the error message the new exception should encapsulate.
mode – The parameter mode specifies whether the constructed hpx::error_code belongs to the error category hpx_category (if mode is plain, this is the default) or to the category hpx_category_rethrow (if mode is rethrow).

Throws

std::bad_alloc – (if allocation of a copy of the passed string fails).

error_code(error e, char const *msg, char const *func, char const *file, long line, throwmode mode = throwmode::plain)#

Construct an object of type error_code.

Parameters

e – The parameter e holds the hpx::error code the new exception should encapsulate.
msg – The parameter msg holds the error message the new exception should encapsulate.
func – The name of the function where the error was raised.
file – The file name of the code where the error was raised.
line – The line number of the code line where the error was raised.
mode – The parameter mode specifies whether the constructed hpx::error_code belongs to the error category hpx_category (if mode is plain, this is the default) or to the category hpx_category_rethrow (if mode is rethrow).

Throws

std::bad_alloc – (if allocation of a copy of the passed string fails).

error_code(error e, std::string const &msg, throwmode mode = throwmode::plain)#

Construct an object of type error_code.

Parameters

e – The parameter e holds the hpx::error code the new exception should encapsulate.
msg – The parameter msg holds the error message the new exception should encapsulate.
mode – The parameter mode specifies whether the constructed hpx::error_code belongs to the error category hpx_category (if mode is plain, this is the default) or to the category hpx_category_rethrow (if mode is rethrow).

Throws

std::bad_alloc – (if allocation of a copy of the passed string fails).

error_code(error e, std::string const &msg, char const *func, char const *file, long line, throwmode mode = throwmode::plain)#

Construct an object of type error_code.

Parameters

e – The parameter e holds the hpx::error code the new exception should encapsulate.
msg – The parameter msg holds the error message the new exception should encapsulate.
func – The name of the function where the error was raised.
file – The file name of the code where the error was raised.
line – The line number of the code line where the error was raised.
mode – The parameter mode specifies whether the constructed hpx::error_code belongs to the error category hpx_category (if mode is plain, this is the default) or to the category hpx_category_rethrow (if mode is rethrow).

Throws

std::bad_alloc – (if allocation of a copy of the passed string fails).

std::string get_message() const#

Return a reference to the error message stored in the hpx::error_code.

Throws: nothing –

inline void clear()#

Clear this error_code object. The postconditions of invoking this method are.

value() == hpx::error::success and category() == hpx::get_hpx_category()

error_code(error_code const &rhs)#: Copy constructor for error_code

Note

This function maintains the error category of the left hand side if the right hand side is a success code.

error_code &operator=(error_code const &rhs)#: Assignment operator for error_code

Note

This function maintains the error category of the left hand side if the right hand side is a success code.
