- <string>(:auto !!!:) Traditionally, when using exceptions to report failures, the throw site: *creates an exception object of the appropriate type, and *stuffs it with data relevant to the detected error. A higher context in the program contains a catch statement which: *selects failures based on exception types, and *inspects exception objects for data required to deal with the problem. The main issue with this "traditional" approach is that often, the data available at the point of the throw is insufficient for the catch site to handle the failure. Here is an example of a catch statement: [@catch( file_read_error & e ) { std::cerr << e.file_name(); }@] And here is a possible matching throw: [@void read_file( FILE * f ) { .... size_t nr=fread(buf,1,count,f); if( ferror(f) ) throw file_read_error(???); ....&#
10; }@] Clearly, the problem is that the handler requires a file name but the read_file function does not have a file name to put in the exception object; all it has is a FILE pointer! In an attempt to deal with this problem, we could modify read_file to accept a file name: [@void read_file( FILE * f, char const * name ) { .... size_t nr=fread(buf,1,count,f); if( ferror(f) ) throw file_read_error(name); .... }@] This is not a real solution: it simply shifts the burden of supplying a file name to the immediate caller of the read_file function. ->''In general, the data required to handle a given library-emitted exception depends on the program that links to it. Many contexts between the throw and the catch may have relevant information which must be transported to the exception handler.'' !!!Exception wrapping The idea of exception wrapping is to catch an exce
ption from a lower level function (such as the read_file function above), and throw a new exception object that contains the original exception (and also carries a file name.) This method seems to be particularly popular with C++ programmers with Java background. Exception wrapping leads to the following problems: *To wrap an exception object it must be copied, which may result in slicing. *Wrapping is practically impossible to use in generic contexts. The second point is actually special case of violating the exception neutrality principle. Most contexts in a program can not handle exceptions; such contexts should not interfere with the process of exception handling. !!!The boost::exception solution *Simply derive your exception types from boost::(:link </string>

- <string>(:auto !!:) Some exception hierarchies can not be modified to make boost::(:link </string>
+ <string>(:auto !!!:) Traditionally, when using exceptions to report failures, the throw site: *creates an exception object of the appropriate type, and *stuffs it with data relevant to the detected error. A higher context in the program contains a catch statement which: *selects failures based on exception types, and *inspects exception objects for data required to deal with the problem. The main issue with this "traditional" approach is that often, the data available at the point of the throw is insufficient for the catch site to handle the failure. Here is an example of a catch statement: [@catch( file_read_error & e ) { std::cerr << e.file_name(); }@] And here is a possible matching throw: [@void read_file( FILE * f ) { .... size_t nr=fread(buf,1,count,f); if( ferror(f) ) throw file_read_error(???); ....&#
10; }@] Clearly, the problem is that the handler requires a file name but the read_file function does not have a file name to put in the exception object; all it has is a FILE pointer! In an attempt to deal with this problem, we could modify read_file to accept a file name: [@void read_file( FILE * f, char const * name ) { .... size_t nr=fread(buf,1,count,f); if( ferror(f) ) throw file_read_error(name); .... }@] This is not a real solution: it simply shifts the burden of supplying a file name to the immediate caller of the read_file function. ->''In general, the data required to handle a given library-emitted exception depends on the program that links to it. Many contexts between the throw and the catch may have relevant information which must be transported to the exception handler.'' !!!Exception wrapping The idea of exception wrapping is to catch an exce
ption from a lower level function (such as the read_file function above), and throw a new exception object that contains the original exception (and also carries a file name.) This method seems to be particularly popular with C++ programmers with Java background. Exception wrapping leads to the following problems: *To wrap an exception object it must be copied, which may result in slicing. *Wrapping is practically impossible to use in generic contexts. The second point is actually special case of violating the exception neutrality principle. Most contexts in a program can not handle exceptions; such contexts should not interfere with the process of exception handling. !!!The boost::exception solution *Simply derive your exception types from boost::(:link </string>

- <string>(:auto !!!:) Sometimes the throw site does not have all the information that is needed at the catch site to make sense of what went wrong. Let's say we have an exception type file_read_error, which takes a file name in its constructor. Consider the following function: [@void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw file_read_error(????); }@] How can the file_read function pass a file name to the exception type constructor?

- <string>(:auto !!!:) Exception types should use virtual inheritance when deriving from other exception types. This insight is due to Andrew Koenig. Using virtual inheritance prevents ambiguity problems in the exception handler: [@#include <iostream> struct my_exc1 : std::exception { char const* what() const throw(); }; struct my_exc2 : std::exception { char const* what() const throw(); }; struct your_exc3 : my_exc1, my_exc2 {}; int main() { try { throw your_exc3(); } catch(std::exception const& e) {} catch(...) { std::cout << "whoops!" << std::endl; } }@] The program above outputs "whoops!" because the conversion to std::exception is ambiguous. The overhead introduced by virtual inheritance is always negligible in the context of exception handling. Note that virtual bases are initialized directly by the constructor of the most-derived-type (the type pass
