namespace Poco {
class Foundation_API Exception: public std::exception
This is the base class for all exceptions defined
in the Poco class library.
{
public:
Exception(const std::string& msg, int code = 0);
Creates an exception.
Exception(const std::string& msg, const std::string& arg, int code = 0);
Creates an exception.
Exception(const std::string& msg, const Exception& nested, int code = 0);
Creates an exception and stores a clone
of the nested exception.
Exception(const Exception& exc);
Copy constructor.
~Exception() throw();
Destroys the exception and deletes the nested exception.
Exception& operator = (const Exception& exc);
Assignment operator.
virtual const char* name() const throw();
Returns a static string describing the exception.
virtual const char* className() const throw();
Returns the name of the exception class.
virtual const char* what() const throw();
Returns a static string describing the exception.
Same as name(), but for compatibility with std::exception.
const Exception* nested() const;
Returns a pointer to the nested exception, or
null if no nested exception exists.
const std::string& message() const;
Returns the message text.
int code() const;
Returns the exception code if defined.
std::string displayText() const;
Returns a string consisting of the
message name and the message text.
virtual Exception* clone() const;
Creates an exact copy of the exception.
The copy can later be thrown again by
invoking rethrow() on it.
virtual void rethrow() const;
(Re)Throws the exception.
This is useful for temporarily storing a
copy of an exception (see clone()), then
throwing it again.
protected:
Exception(int code = 0);
Standard constructor.
private:
std::string _msg;
Exception* _pNested;
int _code;
};
//
// inlines
//
inline const Exception* Exception::nested() const
{
return _pNested;
}
inline const std::string& Exception::message() const
{
return _msg;
}
inline int Exception::code() const
{
return _code;
}
//
// Macros for quickly declaring and implementing exception classes.
// Unfortunately, we cannot use a template here because character
// pointers (which we need for specifying the exception name)
// are not allowed as template arguments.
