public class Base64OutputStream extends FilterOutputStream
Base64
for an explanation of the rationale
for creating the variants in this package.
Provides Base64 encoding and decoding in a streaming fashion (unlimited size).
The behaviour of the Base64OutputStream is to ENCODE, whereas the behaviour of the Base64InputStream is to DECODE.
This class implements section 6.8. Base64 Content-Transfer-Encoding from RFC 2045 Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies by Freed and Borenstein.
Since this class operates directly on byte streams, and not character streams, it is hard-coded to only encode/decode character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, UTF-8, etc).

Constructor and Description |
---|
Base64OutputStream(OutputStream out)
Creates a Base64OutputStream such that all data written is either Base64-encoded to the
original provided OutputStream.
|
Modifier and Type | Method and Description |
---|---|
void |
close()
Closes this output stream and releases any system resources associated with the stream.
|
void |
flush()
Flushes this output stream and forces any buffered output bytes to be written out to the stream.
|
void |
write(byte[] b,
int offset,
int len)
Writes
len bytes from the specified b array starting at offset to this
output stream. |
void |
write(int i)
Writes the specified
byte to this output stream. |
