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.
+BOOST_NO_EXCEPTIONS
+This macro disables exception handling in Boost, forwarding all exceptions to a user-defined non-template version of boost::throw_exception. However, unless BOOST_EXCEPTION_DISABLE is also defined, users can still examine the exception object for any data added at the point of the throw, or use boost::diagnostic_information (of course under BOOST_NO_EXCEPTIONS, the user-defined boost::throw_exception is not allowed to return to the caller.)

- <id>-35</id>
+ <id>-37</id>

(:include synopsis:)

!!!!Requirements:

T must be a class with an accessible no-throw copy constructor as per (15.5.1).

!!!!Returns:

* If T derives from boost::(:link </string>
+ <string>:) allows this to be done directly in a throw expression:

[@throw error() (:link </string>

* Otherwise, the returned object is of an unspecified type that derives publicly from both T and boost::(:link </string>

which saves typing compared to this possible alternative:

[@error e;
e.add(foo_info(foo));
e.add(bar_info(bar));
throw e;@]

and looks better than something like:

[@throw error().add(foo_info(foo)).add(bar_info(bar));@]

!!!Why is boost::exception abstract?

To prevent exception-neutral contexts from erroneously erasing the type of the original exception when adding (:link </string>

!!!Why use operator<< overload for adding info to exceptions?

Before throwing an object of type that derives from boost::(:link </string>

[@throw error().add(foo_info(foo)).add(bar_info(bar));@]

!!!Why is boost::exception abstract?

To prevent exception-neutral contexts from erroneously erasing the type of the original exception when adding (:link </string>
+ <string>:). Such concerns are dictated by the typical strict interpretation of a common principle in C and C++, that users only pay for features they actually use.

The problem is that users of Boost Exception can't by themselves cause a library to throw types that derive from boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>
- <id>-36</id>

 </weak_ptr>
 <variant>2</variant>
- <string>:) to an active exception object:

[@catch( boost::(:link </string>
+ <string>:), and without this they can't use any of the Boost Exception facilities.

For example, if a user wants to use Boost Serialization in a separate thread, it is desirable to be able to transport exceptions emitted by that library into the main thread where they can be analyzed to generate a user-friendly message. This can be easily achieved using boost::(:link </string>
 <variant>1</variant>

+ <id>-12</id>

- <id>-35</id>

 }@]

The correct code is:

[@catch( boost::(:link </string>
+ <string>:) to throw, this behavior happens automatically and transparently.

The cost of this integration is:

* In terms of space: a pointer and 3 ints are added to the static size of exception objects.
* In terms of speed: the pointer is initialized to null at the point of the throw.
* In terms of coupling: about 400 self-contained lines of C++ with no external includes.

!!!!Requirements:

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>-35</id>
+ <id>-37</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:), or a type that derives (indirectly) from boost::(:link </string>
+ <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>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-35</id>

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.

!!!!Requirements:

T must be a class with an accessible no-throw copy constructor.

!!!!Returns:

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

!!!!Description:



This function is designed to be used directly in a throw-expression to enable the (:link </string>

 }@]

In a higher exception-neutral context, we add the file name to ''any'' exception that derives from boost::(:link </string>
+ <string>:) support in Boost Exception. For example:

[@class
my_exception:
 public std::exception
 {
 };

....
throw boost::(:link </string>
 <variant>1</variant>

 <expired>0</expired>
 <shared_ptr>

 </weak_ptr>

- <string>:):

[@typedef boost::(:link </string>

Unless (:link </string>

....
try
 {

 read_file(fp); //throws types deriving from boost::(:link </string>

Finally here is how the handler retrieves data from exceptions that derive from boost::(:link </string>

 {
