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

Error::Error | ( | ErrorCode | ec, | |
string | msg | |||
) |
Create an instance with a specific code and message string. This ctor provides a way to to use any code and string you'd like. The code can be one of the standard codes or it may be specific to your server. Thus a client which can tell it's dealing with a specific type of server can use the code accordingly. In general, clients simply show the error message to users or write it to a log file.
ec | The error code | |
msg | The error message string. |
Error::Error | ( | string | msg | ) |
Error::Error | ( | ) |
Error::Error | ( | const Error & | copy_from | ) |
ErrorCode Error::get_error_code | ( | ) | const |
Get the ErrorCode for this instance.

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. |

Here is the call graph for this function:
void Error::set_error_code | ( | ErrorCode | ec = undefined_error |
) |
Set the ErrorCode. If the current error message has not been set, use ec to set the error message. The resulting error message string is the same as the ErrorCode name. If ec is not within the range of values for an OPeNDAP ErrorCode, the error message is left unchanged.
ec | The new ErrorCode value. |
