Class UUEncoderStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

com.sun.mail.util.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.

Constructor Detail

UUEncoderStream

public UUEncoderStream(java.io.OutputStream out)

Create a UUencoder that encodes the specified input stream

Parameters:

out - the output stream

UUEncoderStream

public UUEncoderStream(java.io.OutputStream out,
                       java.lang.String name)

Create a UUencoder that encodes the specified input stream

Parameters:

out - the output stream

name - Specifies a name for the encoded buffer

UUEncoderStream

public UUEncoderStream(java.io.OutputStream out,
                       java.lang.String name,
                       int mode)

Create a UUencoder that encodes the specified input stream

Parameters:

out - the output stream

name - Specifies a name for the encoded buffer

mode - Specifies permission mode for the encoded buffer

Method Detail

setNameMode

public void setNameMode(java.lang.String name,
                        int mode)

Set up the buffer name and permission mode. This method has any effect only if it is invoked before you start writing into the output stream

Parameters:

name - the buffer name

mode - the permission mode

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Overrides:

write in class java.io.FilterOutputStream

Throws:

java.io.IOException

write

public void write(byte[] data)
           throws java.io.IOException

Overrides:

write in class java.io.FilterOutputStream

Throws:

java.io.IOException

write

public void write(int c)
           throws java.io.IOException

Overrides:

write in class java.io.FilterOutputStream

Throws:

java.io.IOException

flush

public void flush()
           throws java.io.IOException

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.FilterOutputStream

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.FilterOutputStream

Throws:

java.io.IOException

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
