public class Base64EncoderStream
extends FilterOutputStream

This class implements a BASE64 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 Detail

Base64EncoderStream

public Base64EncoderStream(OutputStream out)

Base64EncoderStream

public Base64EncoderStream(XMLStreamWriter outWriter,
                           OutputStream out)
Create a BASE64 encoder that encodes the specified input stream

Method Detail

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

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 Closeable
Overrides:
close in class FilterOutputStream
Throws:
IOException
