Detailed Description

Concept for reading and writing characters.

For read-only stream, no need to implement PutBegin(), Put(), Flush() and PutEnd().

For write-only stream, only need to implement Put() and Flush().

concept Stream {
   typename Ch;   //!< Character type of the stream.

   //! Read the current character from stream without moving the read cursor.
   Ch Peek() const;

   //! Read the current character from stream and moving the read cursor to next character.
   Ch Take();

   //! Get the current read cursor.
   //! \return Number of characters read from start.
   size_t Tell();

   //! Begin writing operation at the current read pointer.
   //! \return The begin writer pointer.
   Ch* PutBegin();

   //! Write a character.
   void Put(Ch c);

   //! Flush the buffer.
   void Flush();

   //! End the writing operation.
   //! \param begin The begin write pointer returned by PutBegin().
   //! \return Number of characters written.
   size_t PutEnd(Ch* begin);
