Class LineInputStream

  • All Implemented Interfaces:
    Closeable, AutoCloseable

    public class LineInputStream
    extends FilterInputStream
    This class is to support reading CRLF terminated lines that contain only US-ASCII characters from an input stream. Provides functionality that is similar to the deprecated DataInputStream.readLine(). Expected use is to read lines as String objects from a RFC822 stream. It is implemented as a FilterInputStream, so one can just wrap this class around any input stream and read bytes from this filter.

        public String readLine()
                        throws IOException
        Read a line containing only ASCII characters from the input stream. A line is terminated by a CR or NL or CR-NL sequence. A common error is a CR-CR-NL sequence, which will also terminate a line. The line terminator is not returned as part of the returned String. Returns null if no data is available.
