Detailed Description

The base class for all SWORD exceptions. It contains a textual message, which you can access using the what() method. It implements the std::exception interface.

When you build an exception, the content of the stream "sword::estream" is automatically used as the message, and then the stream is cleared. The exception message stream is thread-local, so different exception messages can be built simultaneously in different threads.

     sword::estream << "The error context is : value=" << value;
     throw sword::Exception();
  

You can also define your own exception classes by deriving from sword::Exception:

     class MyException : public sword::Exception {};
