Just wanted to ask if there were commonly accepted solutions to the
following problem:
typedef boost::error_info f1_descr;
and then
throw f1exception() << f1_descr("blah blah blah").
and later
catch(f1exception & ex){...}
The constructor of std::string may throw an exception in which case
f1exception will never be thrown.
This is not necessarily the desired outcome as the intention was
obviously to indicate f1exception error,
not the string() error.
This problem pertains to any type that throws exceptions in its
constructor and is used with error_info idiom.
What may be more appropriate is something like this
typedef boost::error_info
f1_descr
...
error condition is detected
shared_ptr<string> pErrStr;
try
{
pErrStr = new string("Error description");
}
catch(bad_alloc & ex)
{
}
throw f1exception() << f1_descr(pErrStr);
Meaning that if string fails to allocate memory, I'm willing to forgo
the
error description but still throw the intended exception.
Is there a cleaner way to do that?
Thanks,
Andy.
