Inheritance diagram for Error:
Public Member Functions | |
Error (const Error ©_from) | |
Copy constructor. | |
Error () | |
Create a default Error object. | |
Error (string msg) | |
Create an instance with the unknown_error code. | |
Error (ErrorCode ec, string msg) | |
Create an instance with an error code and a message. | |
ErrorCode | get_error_code () const |
Get the error code. | |
string | get_error_message () const |
Get the error message. | |
bool | OK () const |
Class invariant. | |
Error & | operator= (const Error &rhs) |
bool | parse (FILE *fp) |
Deserialize object from the wire. | |
void | print (FILE *out) const |
Print the Error object on the given output stream. | |
void | set_error_code (ErrorCode ec=undefined_error) |
Set the error code. | |
void | set_error_message (string msg="") |

This class is used on both clients and servers. The print() and parse() methods are used to send the object back and forth.

Here is the call graph for this function:
string Error::get_error_message | ( | ) | const |
Return the current error message.

Here is the call graph for this function:
bool Error::OK | ( | ) | const |
Use this function to determine whether an Error object is valid. To be a valid, an Error object must either be: 1) empty or contain a message and a code.

References _error_code, _error_message, _program, _program_type, and OK().
Here is the call graph for this function:
bool Error::parse | ( | FILE * | fp | ) |
Given an input stream (FILE *) fp
, parse an Error object from stream. Values for fields of the Error object are parsed and this
is set accordingly. This is how a client program receives an error object from a server.
fp | A valid file pointer to an input stream. |

Here is the call graph for this function:
void Error::print | ( | FILE * | out | ) | const |
Creates a printable representation of the Error object. It is suitable for framing, and also for printing and sending over a network.
The printed representation produced by this function can be parsed by the parse() member function. Thus parse and print form a symmetrical pair that can be used to send and receive an Error object over the network in a MIME document.
out | A pointer to the output stream on which the Error object is to be rendered. |
