                    | BufferedReader | 
                    
                       Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.

                       This class implements a character buffer that can be used as a character-input stream.

                       Reads text from character files using a default buffer size.

                    | InputStreamReader | 
                    
                       An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified .

                       A buffered character-input stream that keeps track of line numbers.

                       A character-stream reader that allows characters to be pushed back into the stream.

                    | StringReader | 
                    
                       A character stream whose source is a string.

    A Readable is a source of characters. Characters from a Readable are made available to callers of the read method via a CharBuffer.

    Public methods
    
      read
      
      abstract fun read(cb: CharBuffer!): Int
      Attempts to read characters into the specified character buffer. The buffer is used as a repository of characters as-is: the only changes made are the results of a put operation. No flipping or rewinding of the buffer is performed.
      
        
          
            | Parameters | 
          
          
            cb | 
            CharBuffer!: the buffer to read characters into | 
          
        
      
      
        
          
            | Return | 
          
          
            Int | 
            The number of char values added to the buffer, or -1 if this source of characters is at its end | 
          
        
      
      
        
          
            | Exceptions |

            if an I/O error occurs | 
          
          
            java.lang.NullPointerException | 
            if cb is null | 
          
          
            java.nio.ReadOnlyBufferException |
