The ability to add data to exception objects after they have been passed to throw is important, because often some of the information needed to handle an exception is unavailable in the context where the failure is detected.

Boost Exception also supports N2179-style copying of exception objects, implemented non-intrusively and automatically by the boost::throw_exception function.

Data can be added to any exception object, either directly in the throw-expression (15.1), or at a later time as the exception object propagates up the call stack. The ability to add data to exception objects after they have been passed to throw is important, because often some of the information needed to handle an exception is unavailable in the context where the failure is detected.

However, the file_read function does not have the file name at the time of the throw; all it has is a FILE handle. One possible solution is to not use FILE handles directly. We could have our own class file which stores both a FILE handle and a file name, and pass that to file_read. However, this could be problematic if we communicate with 3rd party code that does not use our class file (probably because they have their own similar class.) A better solution is to make class file_read_error derive (possibly indirectly) from boost::(:link + 1 + + 0 + + -19 + + + 2 + :), and free the file_read function from the burden of storing the file name in exceptions it throws: [@#include <(:link + 1 + + 0 + + -29 + + + 2 + :)> #include <stdio.h> #include <errno.h> typedef boost::(:link + 1 + + 0 + + -20 + + + 2 + :)<struct tag_errno,int> errno_info; class file_read_error: public boost::(:link + 1 + + 0 + + -19 + + + 2 + :) { }; void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw file_read_error() << errno_info(errno); }@] If file_read detects a failure, it throws an exception which contains the information that is available at the time, namely the errno. Other relevant information, such as the file name, can be added in a context higher up the call stack, where it is known naturally: [@#include <(:link + 1 + + 0 + + -29 + + + 2 + :)> #include <boost/shared_ptr.hpp> #include <stdio.h> #include <string> typedef boost::(:link + 1 + + 0 + + -20 + + + 2 + :)<struct tag_file_name,std::string> file_name_info; boost::shared_ptr<FILE> file_open( char const * file_name, char const * mode ); void file_read( FILE * f, void * buffer, size_t size ); void parse_file( char const * file_name ) { boost::shared_ptr<FILE> f = file_open(file_name,"rb"); assert(f); try { char buf[1024]; file_read( f.get(), buf, sizeof(buf) ); } catch( boost::(:link + 1 + + 0 + + -19 + + + 2 + :) & e ) { e << file_name_info(file_name); throw; } }@] The above function is (almost) exception-neutral -- if an exception is emitted by any function call within the try block, parse_file does not need to do any real work, but it intercepts any boost::(:link + 1 + + 0 + + -19 + + + 2 + :) object, stores the file name, and re-throws using a throw-expression with no operand (15.1.6). The rationale for catching any boost::(:link + 1 + + 0 + + -19 + + + 2 + :) object is that the file name is relevant to any failure that occurs in parse_file, ''even if the failure is unrelated to file I/O''.

However, the file_read function does not have the file name at the time of the throw; all it has is a FILE handle. One possible solution is to not use FILE handles directly. We could have our own class file which stores both a FILE handle and a file name, and pass that to file_read. However, this could be problematic if we communicate with 3rd party code that does not use our class file (probably because they have their own similar class.) A better solution is to make class file_read_error derive (possibly indirectly) from boost::(:link - 1 - - 0 - - -37 - - - 2 - :), and free the file_read function from the burden of storing the file name in exceptions it throws: [@#include <(:link - 1 - - 0 - - -40 - - - 2 - :)> #include <stdio.h> #include <errno.h> typedef boost::(:link - 1 - - 0 - - -38 - - - 2 - :)<struct tag_errno,int> errno_info; class file_read_error: public boost::(:link - 1 - - 0 - - -37 - - - 2 - :) { }; void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw file_read_error() << errno_info(errno); }@] If file_read detects a failure, it throws an exception which contains the information that is available at the time, namely the errno.

The rationale for catching any boost::(:link - 1 - - 0 - - -37 - - - 2 - :) object is that the file name is relevant to any failure that occurs in parse_file, ''even if the failure is unrelated to file I/O''.

Diagnostic Information

Class boost::exception provides a virtual member function diagnostic_information, with a signature similar to the familiar std::exception::what function. The default implementation returns a string value that is not presentable as a friendly user message, but because it is generated automatically, it is useful for debugging or logging purposes. Here is an example:

#include <boost/exception.hpp>

Some exception hierarchies can not be modified to make boost::exception a base type. In this case, the enable_error_info function template can be used to make exception objects derive from boost::exception anyway. Here is an example:

Boost Exception supports transporting of exception objects between threads through cloning. This system is similar to N2179, but because Boost Exception can not rely on language support, the use of enable_current_exception at the time of the throw is required in order to use cloning.

 
Note:

 
All exceptions emitted by the familiar function boost::throw_exception are guaranteed to derive from boost::exception and to support cloning.

All exception types that derive from boost::exception can be used as type-safe containers of arbitrary data objects, while complying with the no-throw requirements (15.5.1) of the ANSI C++ standard for exception types. Data can be added to a boost::exception at the time of the throw, or at a later time.

The get_error_info function template is instantiated with the typedef from (1), and is passed an exception object of a polymorphic type. If the exception object contains the requested value, the returned shared_ptr will point to it; otherwise an empty shared_ptr is returned.

The above function is (almost) exception-neutral -- if an exception is emitted by any function call within the try block, parse_file does not need to do any real work, but it intercepts any boost::exception object, stores the file name, and re-throws using a throw-expression with no operand (15.1.6). The rationale for catching any boost::exception object is that the file name is relevant to any failure that occurs in parse_file, even if the failure is unrelated to file I/O.

 
As usual, the stored data can be retrieved using get_error_info.
