  class Foundation_API TeeStreamBuf: public UnbufferedStreamBuf

This stream buffer copies all data written to or read from it to one or multiple output streams. { public: TeeStreamBuf(); Creates an unconnected CountingStreamBuf. Use addStream() to attach output streams. TeeStreamBuf(std::istream& istr); Creates the CountingStreamBuf and connects it to the given input stream.


          TeeStreamBuf(std::ostream& ostr);

Creates the CountingStreamBuf and connects it to the given output stream.


          ~TeeStreamBuf();

Destroys the CountingStream.


          void addStream(std::ostream& ostr);

Adds the given output stream.

  class Foundation_API TeeIOS: public virtual std::ios

The base class for TeeInputStream and TeeOutputStream. This class is needed to ensure the correct initialization order of the stream buffer and base classes. { public: TeeIOS(); Creates the basic stream and leaves it unconnected.


          TeeIOS(std::istream& istr);

Creates the basic stream and connects it to the given input stream.


          TeeIOS(std::ostream& ostr);

Creates the basic stream and connects it to the given output stream.


          ~TeeIOS();

Destroys the stream.


          void addStream(std::ostream& ostr);

Adds the given output stream.


          TeeStreamBuf* rdbuf();

Returns a pointer to the underlying streambuf.


  protected:
          TeeStreamBuf _buf;
  };
  
  class Foundation_API TeeInputStream: public TeeIOS, public std::istream

This stream copies all characters read through it to one or multiple output streams. { public: TeeInputStream(std::istream& istr); Creates the TeeInputStream and connects it to the given input stream.


          ~TeeInputStream();

Destroys the TeeInputStream. };


  class Foundation_API TeeOutputStream: public TeeIOS, public std::ostream

This stream copies all characters written to it to one or multiple output streams. { public: TeeOutputStream(); Creates an unconnected TeeOutputStream. TeeOutputStream(std::ostream& ostr); Creates the TeeOutputStream and connects it to the given input stream.


          ~TeeOutputStream();

Destroys the TeeOutputStream. };
