                Detailed Description

                Duplicate all data passed by the stream operator to two output streams.

                Can be used as replacement for any OutputStream – for example, forwarding the DBG output simultaneously to screen (TextStream) and serial console (SerialStream).

                By using template programming, two generic methods are sufficient (which simply forward the input to both).

                Constructor & Destructor Documentation

                CopyStream::CopyStream ( OutputStream *  first,
                OutputStream *  second 
                )
                inline

                Constructor.

                Parameters
                firstFirst recipient for output passed to this object
                secondSecond recipient for output passed to this object

                Member Function Documentation

                template<typename T >
                CopyStream & CopyStream::operator<< ( T  value)
                inline

                Generic stream operator for any data type.

                Forwards all input to both recipients.

                Uses template meta programming for a generic & short solution

                Template Parameters
                TType of data to be forwarded
                Parameters
                valuedata to be forwarded
                Returns
                Reference to the CopyStream object allowing concatenation of operators
                Optional:
                Implement method
                template<typename T >
                CopyStream & CopyStream::operator<< ( T &(*)(T &)  f)
                inline

                Deal with [OutputStream] manipulator functions.

                Template Parameters
                TManipulator type
                Parameters
                fpointer to manipulator function
                Returns
                Reference to the CopyStream object allowing concatenation of operators
