public Class Base64EncoderStream

extends FilterOutputStream
Class Inheritance
Imports
java.io.*, java.util.logging.Level, .Logger, javax.xml.stream.XMLStreamException, .XMLStreamWriter
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.

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 void
write(int
the byte.
c)

Overrides java.io.FilterOutputStream.write.

Encodes the specified byte to this output stream.
