Class Base64EncoderStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

org.jvnet.staxex.Base64EncoderStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public class Base64EncoderStream
extends java.io.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(javax.xml.stream.XMLStreamWriter outWriter,
                           java.io.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 java.io.IOException

Encodes len bytes from the specified byte array starting at offset off to this output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

Throws:

java.io.IOException - if an I/O error occurs.

write

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

Encodes b.length bytes to this output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

b - the data to be written.

Throws:

java.io.IOException - if an I/O error occurs.

write

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

Encodes the specified byte to this output stream.

Overrides:

write in class java.io.FilterOutputStream

Parameters:

c - the byte.

Throws:

java.io.IOException - if an I/O error occurs.

flush

public void flush()
           throws java.io.IOException

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

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.FilterOutputStream

Throws:

java.io.IOException - if an I/O error occurs.

close

public void close()
           throws java.io.IOException

Forces any buffered output bytes to be encoded out to the stream and closes this output stream

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

encode

private void encode()
             throws java.io.IOException

Throws:

java.io.IOException
