Class UUEncoderStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    public class UUEncoderStream
extends java.io.FilterOutputStream
    This class implements a UUEncoder. It is implemented as a FilterOutputStream, so one can just wrap this class around any output stream and write bytes into this filter. The Encoding is done as the bytes are written out.

        Throws:
        java.io.IOException

      • close

        public void close()
           throws java.io.IOException
        Specified by:

        Overrides:
        close in class java.io.FilterOutputStream
        Throws:

      • writePrefix

        private void writePrefix()
                  throws java.io.IOException
        Write out the prefix: "begin "
        Throws:
        java.io.IOException

      • writeSuffix

        private void writeSuffix()
                  throws java.io.IOException
        Write a single line containing space and the suffix line containing the single word "end" (terminated by a newline)
        Throws:
        java.io.IOException

      • encode

        private void encode()
             throws java.io.IOException
        Encode a line. Start off with the character count, followed by the encoded atoms and terminate with LF. (or is it CRLF or the local line-terminator ?) Take three bytes and encodes them into 4 characters If bufsize if not a multiple of 3, the remaining bytes are filled with '1'. This insures that the last line won't end in spaces and potentiallly be truncated.
        Throws:
        java.io.IOException
