    Configuration Macros

    Boost Exception responds to the following configuration macros:

    -

    BOOST_NO_RTTI/BOOST_NO_TYPEID

    -

    The first macro prevents Boost Exception from using dynamic_cast and dynamic typeid. If the second macro is also defined, Boost Exception does not use static typeid either. Defining either macro does not have an observable degrading effect on the library functionality, except for the following:

    +

    BOOST_NO_RTTI 
    BOOST_NO_TYPEID

    +

    The first macro prevents Boost Exception from using dynamic_cast and dynamic typeid. If the second macro is also defined, Boost Exception does not use static typeid either. There are no observable degrading effects on the library functionality, except for the following:

    By default, the get_error_info function template can be called with any exception type. If BOOST_NO_RTTI is defined, get_error_info can be used only with objects of type boost::exception.

    -

    Note: the configuration where BOOST_NO_RTTI is defined but BOOST_NO_TYPEID is not defined is specific for MSVC compilers; it reduces RTTI overhead without fully disabling std::type_info. For most (all?) other compilers, to use Boost Exception without RTTI, both BOOST_NO_RTTI and BOOST_NO_TYPEID must be defined.

    BOOST_EXCEPTION_DISABLE

    By default, enable_current_exception and enable_error_info are integrated directly in the throw_exception function. Defining BOOST_EXCEPTION_DISABLE disables this integration.

    Note that on some non-conformant compilers, for example MSVC 7.0 and older, as well as BCC, BOOST_EXCEPTION_DISABLE is implicitly defined in boost/throw_exception.hpp.

It supports transporting of arbitrary data to the catch site, which is otherwise tricky due to the no-throw requirements (15.5.1) for exception types. 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.

It supports transporting of arbitrary data to the catch site, which is otherwise tricky due to the no-throw requirements (15.5.1) for exception types. 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.

If the second macro is also defined, Boost Exception does not use static typeid either. Defining either macro does not have an observable degrading effect on the library functionality, except for the following: ->By default, the - 1 - - 0 - - -15 - - - 2 - function template can be called with any exception type. If BOOST_NO_RTTI is defined, - 1 - - 0 - - -15 - - - 2 - can be used only with objects of type boost:: - 1 - - 0 - - -11 - - - 2 - . ''Note: the configuration where BOOST_NO_RTTI is defined but BOOST_NO_TYPEID is not defined is specific for MSVC compilers; it reduces RTTI overhead without fully disabling std::type_info. For most (all?) other compilers, to use Boost Exception without RTTI, both BOOST_NO_RTTI and BOOST_NO_TYPEID must be defined.'' '''BOOST_EXCEPTION_DISABLE''' By default, - 1 - - 0 - - -18 - - - 2 - and - 1 - - 0 - - -16 - - - 2 - are integrated directly in the - 1 - - 0 - - -7 - - - 2 - function.

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.)

The returned string contains: *the string representation of all data objects added to the boost::(:link + 1 + + 0 + + -40 + + + 2 + :) through (:link + 1 + + 0 + + -32 + + + 2 + mod="/":); *the output from std::exception::what; *additional platform-specific diagnostic information. The returned string 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 <(:link + 1 + + 0 + + -25 + + + 2 + :)> #include <iostream> void f(); //throws unknown types that derive from boost::(:link + 1 + + 0 + + -40 + + + 2 + :). void g() { try { f(); } catch( boost::(:link + 1 + + 0 + + -40 + + + 2 + :) & e ) { std::cerr << (:link + 1 + + 0 + + -29 + + + 2 + :)(e); } }@] + + + + + 0 + + -40 + + + + 13 + 2 + (:auto !!!:) (:include synopsis:) Class boost::(:link + 1 + + 0 + + -40 + + + 2 + :) is designed to be used as a universal base for user-defined exception types. An object of any type deriving from boost::(:link + 1 + + 0 + + -40 + + + 2 + :) can store data of arbitrary types, using the (:link + 1 + + 0 + + -34 + + + 2 + :) wrapper and (:link + 1 + + 0 + + -32 + + + 2 + mod="/":). To retrieve data from a boost::(:link + 1 + + 0 + + -40 + + + 2 + :) object, use the (:link + 1 + + 0 + + -33 + + + 2 + :) function template. + + + + + 0 + + -41 + + + + 11 + 2 + (:auto !!!:) Here is how cloning can be enabled in a throw-expression (15.1): [@#include <(:link + 1 + + 0 + + -17 + + + 2 + :)> #include <stdio.h> #include <errno.h> typedef boost::error_info<struct tag_errno,int> errno_info; class file_read_error: public boost::(:link + 1 + + 0 + + -40 + + + 2 + :) { }; void file_read( FILE * f, void * buffer, size_t size ) { if( size!=fread(buffer,1,size,f) ) throw boost::(:link + 1 + + 0 + + -10 + + + 2 + :)(file_read_error()) << errno_info(errno); }@] Of course, (:link + 1 + + 0 + + -10 + + + 2 + :) may be used with any exception type; there is no requirement that it should derive from boost::(:link + 1 + + 0 + + -40 + + + 2 + :). + + + + + 0 + + -42 + + + + 17 + 2 + (:auto !!!:) (:include synopsis:) The (:link + 1 + + 0 + + -42 + + + 2 + :) type can be used to refer to a copy of an exception object. It is Default Constructible, Copy Constructible, Assignable and Equality Comparable; (:link + 1 + + 0 + + -42 + + + 2 + :)'s operations do not throw. Two instances of (:link + 1 + + 0 + + -42 + + + 2 + :) are equivalent and compare equal if and only if they refer to the same exception. The default constructor of (:link + 1 + + 0 + + -42 + + + 2 + :) produces the null value of the type. The null value is equivalent only to itself. !!!!Thread safety * It is legal for multiple threads to hold (:link + 1 + + 0 + + -42 + + + 2 + :) references to the same exception object. * It is illegal for multiple threads to modify the same (:link + 1 + + 0 + + -42 + + + 2 + :) object concurrently. * While calling (:link + 1 + + 0 + + -20 + + + 2 + :) makes a copy of the current exception object, it is still possible for the two copies to share internal state. Therefore, in general it is not safe to call (:link + 1 + + 0 + + -18 + + + 2 + :) concurrently to throw the same exception object into multiple threads. + + + + + 0 + + -43 + + + + 0 + + + + + 0 + + -44 + + + + 0 + + @@ -6495,51 +6486,7 @@ 0 -

    The call to enable_error_info<T> gets us an object of unspecified type which is guaranteed to derive from both boost::exception and T. This makes it possible to use operator<< to store additional information in the exception object. The exception can be intercepted as T &, so existing exception handling will not break. It can also be intercepted as boost::exception &, so that more information can be added to the exception at a later time.

    First, we instantiate the error_info template using a unique identifier -- tag_errno, and the type of the info it identifies -- int. This provides compile-time type safety for the various values stored in exception objects.

    Second, we define class my_error, which derives from boost::exception.
