Class QPEncoderStream

java.lang.Object

java.io.FilterOutputStream
com.sun.xml.messaging.saaj.packaging.mime.util.QPEncoderStream
All Implemented Interfaces:
Closeable, Flushable, AutoCloseable
Direct Known Subclasses:
QEncoderStream
public class QPEncoderStream extends FilterOutputStream
This class implements a Quoted Printable Encoder. 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.

  • Constructor Details

    • QPEncoderStream

      public QPEncoderStream(OutputStream out, int bytesPerLine)
      Create a QP encoder that encodes the specified input stream
      Parameters:
      out - the output stream
      bytesPerLine - the number of bytes per line. The encoder inserts a CRLF sequence after this many number of bytes.

    • QPEncoderStream

      public QPEncoderStream(OutputStream out)
      Create a QP encoder that encodes the specified input stream. Inserts the CRLF sequence after outputting 76 bytes.
      Parameters:
      out - the output stream

  • Method Details

    • write

      public void write(byte[] b, int off, int len) throws IOException
      Encodes len bytes from the specified byte array starting at offset off to this output stream.
      Overrides:
      write in class FilterOutputStream
      Parameters:
      b - the data.
      off - the start offset in the data.
      len - the number of bytes to write.
      Throws:
      IOException - if an I/O error occurs.

    • write

      public void write(byte[] b) throws IOException
      Encodes b.length bytes to this output stream.
      Overrides:
      write in class FilterOutputStream
      Parameters:
      b - the data to be written.
      Throws:
      IOException - if an I/O error occurs.

    • write

      public void write(int c) throws IOException
      Encodes the specified byte to this output stream.
      Overrides:
      write in class FilterOutputStream
      Parameters:
      c - the byte.
      Throws:
      IOException - if an I/O error occurs.

    • flush

      public void flush() throws IOException

      Specified by:
      flush in interface Flushable
      Overrides:
      flush in class FilterOutputStream
      Throws:
      IOException - if an I/O error occurs.

    • close

      public void close() throws IOException
      Forces any buffered output bytes to be encoded out to the stream and closes this output stream
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Closeable
      Overrides:
      close in class FilterOutputStream
