All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

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.

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 AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class FilterOutputStream

Throws:

IOException
