Added class for catching C++ exceptions. When using libobjc2, you can catch C++ exceptions by writing @catch(CXXException e). This will wrap the C++ exception in an Objective-C object and allow you to access it by sending a -thrownValue message to the object. This returns a pointer to the exception. For example, if the exception is an integer, you would retrieve it like this from Objective-C: @catch(CXXException e) { int i = (int)[e thrownValue]; } In ObjC++, you can also make sure that it really is an int, by doing: assert(typeid(int) == (std::type_info)[e cxx_type_info]); These interfaces are experimental and subject to change without notice. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/base/trunk@30904 72102866-910b-0410-8b05-ffd578937521 2010-06-30 13:08:22 +00:00
