public Class QPEncoderStream

extends FilterOutputStream
Class Inheritance
Known Direct Subclasses
com.sun.mail.util.QEncoderStream
Imports
java.io.*
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.

flush()

Overrides java.io.FilterOutputStream.flush.

Implements java.io.Flushable.flush.

Flushes this output stream and forces any buffered output bytes to be encoded out to the stream.

the data.
b, int
the start offset in the data.
off, int
the number of bytes to write.
len)

Overrides java.io.FilterOutputStream.write.

Encodes len bytes from the specified byte array starting at offset off to this output stream.
public void
write(byte[]
the data to be written.
b)

Overrides java.io.FilterOutputStream.write.

Encodes b.length bytes to this output stream.

public QPEncoderStream(OutputStream out, int bytesPerLine)

Create a QP encoder that encodes the specified input stream

Parameters
out:OutputStream

the output stream

bytesPerLine:int

the number of bytes per line. The encoder inserts a CRLF sequence after this many number of bytes.
