Class Base64OutputStream
FilterOutputStreamgnu.mail.util.Base64OutputStream
public class Base64OutputStream
extends FilterOutputStream
A Base64 content transfer encoding filter stream.
From RFC 2045, section 6.8:
The Base64 Content-Transfer-Encoding is designed to represent
arbitrary sequences of octets in a form that need not be humanly
readable. The encoding and decoding algorithms are simple, but the
encoded data are consistently only about 33 percent larger than the
unencoded data.
void | close()- Closes this output stream and releases any system resources
associated with this stream.
|
void | flush()- Flushes this output stream and forces any buffered output bytes to be
written out.
|
void | write(b[] )- Writes
b.length bytes from the specified byte array
to this output stream.
|
void | write(b[] , int off, int len)- Writes
len bytes from the specified byte array
starting at offset off to this output stream.
|
void | write(int c)- Writes the specified byte to this output stream.
