- Summary
- Use this function to get the dynamic type of a caught C++-UNO exception;
completes the above function throwing exceptions generically.
- Description
- try
{
...
}
catch (::com::sun::star::uno::RuntimeException &)
{
// you ought not handle RuntimeExceptions:
throw;
}
catch (::com::sun::star::uno::Exception &)
{
::com::sun::star::uno::Any caught( ::cppu::getCaughtException() );
...
}
Restrictions:
- use only for caught C++-UNO exceptions (UNOIDL defined)
- only as first statement in a catch block!
- don't do a C++ rethrow (throw;) after you have called this function
- call getCaughtException() just once in your catch block!
(function internally uses a C++ rethrow)
- Return
-
caught UNO exception
- ATTENTION!
- Caution!
This function is limited to the same C++ compiler runtime library.
E.g. for MSVC, this means that the catch handler code (the one
that calls getCaughtException()) needs to use the very same
C++ runtime library, e.g. msvcrt.dll as cppuhelper, e.g.
cppuhelper3MSC.dll and the bridge library, e.g. msci_uno.dll.
This is the case if all of them are compiled with the same
compiler version.
Background: The msci_uno.dll gets a rethrown exception out
of the internal msvcrt.dll thread local storage (tls).
Thus you _must_ not use this function if your code needs to run
in newer UDK versions without being recompiled, because those
newer UDK (-> OOo versions) potentially use newer C++ runtime
libraries which most often become incompatible!
But this function ought to be usable for most OOo internal C++-UNO
development, because the whole OOo code base is compiled using the
same C++ compiler (and linking against one runtime library).
