Detailed Description

RWUException is thrown by many methods in the Internationalization Module. This class is a subclass of RWxmsg in the Essential Tools Module.

An RWUException instance contains a string message and an RWUStatusCode.

As with RWxmsg, the string message contains a textual description of the error, typically in English. The inherited why() method returns the message string contained in self. The RWUStatusCode of an RWUException identifies the type of the error. Member function getStatus() returns the RWUStatusCode.

Example

#include <rw/i18n/RWUException.h>
#include <rw/i18n/RWUCollationKey.h>
#include <iostream>

using std::cout;
using std::endl;

int
main()
{
  // Attempt to use an invalid RWUCollationKey.
  try {
    RWUCollationKey invalidKey;
    cout << invalidKey.getString() << endl;

  // Catch the resulting exception.
  } catch (const RWUException& e) {
    cout << "Unable to obtain string from key:  " <<
     e.why() << endl;
  }

  return 0;
} // main

Program output:

Unable to obtain string from key:  invalid RWUCollationKey
