(:include synopsis:)

!!!!Requirements:

* T must be a class with an accessible no-throw copy constructor.
* If T has any virtual base types, those types must have an accessible default constructor.

!!!!Returns:

An object of ''unspecified'' type which derives publicly from T. That is, the returned object can be intercepted by a catch(T &).

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. There are no observable degrading effects on the library functionality, except for the following:

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? All it has is a FILE handle.

Bjarne Stroustrup, The C++ Programming Language, 3rd Edition, page 371:

->''"Throwing an exception requires an object to throw.  A C++ implementation is required to have enough spare memory to be able to throw bad_alloc in case of memory exhaustion.  However, it is possible that throwing some other exception will cause memory exhaustion."''

So, an attempt to throw any exception may already result in propagating std::bad_alloc instead.

The purpose of Boost Exception is to ease the design of exception class hierarchies and to help write exception handling and error reporting code.

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. 

Boost Exception also supports (:link http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html|N2179:)-style (:link </string>

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>
+													<variant>1</variant>
+													<weak_ptr>
+														<expired>0</expired>
+														<shared_ptr>
+															<id>-11</id>
+														</shared_ptr>
+													</weak_ptr>
+													<variant>2</variant>
+													<string>:).
*Confidently limit the throw site to provide only data that is available naturally.
*Use exception-neutral contexts between the throw and the catch to augment exceptions with more relevant data as they bubble up.

For example, in the throw statement below we only add the errno code, since this is the only failure-relevant information available in this context:

[@struct exception_base: virtual std::exception, virtual boost::(:link </string>

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
ed to the throw statement, in case of exceptions.) However, typically this detail is of no concern when boost::(:link </string>
+													<string>:) which refers to an instance of (:link </string>

`#include <(:link </string>

struct io_error: virtual exception_base { };
struct file_error: virtual io_error { };
struct read_error: virtual io_error { };
struct file_read_error: virtual file_error, virtual read_error { };@]

Using this approach, exception types become a simple tagging system for categorizing errors and selecting failures in exception handlers.

The code snippet below demonstrates how boost::(:link http://www.boost.org/libs/tuple/doc/tuple_users_guide.html|tuple:) can be used to bundle the name of the function that failed, together with the reported errno so that they can be added to exception objects more conveniently together:

[@#include <(:link </string>
+													<variant>1</variant>
+													<weak_ptr>
+														<expired>0</expired>
+														<shared_ptr>
+															<id>-41</id>

                                                                                                         <variant>2</variant>
-													<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>:)>
#include <(:link </string>
                                                                                                         <variant>1</variant>

-													<string>:).
*Confidently limit the throw site to provide only data that is available naturally.
*Use exception-neutral contexts between the throw and the catch to augment exceptions with more relevant data as they bubble up.

For example, in the throw statement below we only add the errno code, since this is the only failure-relevant information available in this context:

When you catch an exception, you can call (: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? All it has is a FILE handle.

->''"Throwing an exception requires an object to throw.  A C++ implementation is required to have enough spare memory to be able to throw bad_alloc in case of memory exhaustion.  However, it is possible that throwing some other exception will cause memory exhaustion."''

So, an attempt to throw any exception may already result in propagating std::bad_alloc instead.

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
ed to the throw statement, in case of exceptions.) However, typically this detail is of no concern when boost::(:link </string>
