public class BASE64EncoderStream
extends java.io.FilterOutputStream
Constructor | Description |
---|---|
BASE64EncoderStream(java.io.OutputStream out) |
Create a BASE64 encoder that encodes the specified input stream.
|
BASE64EncoderStream(java.io.OutputStream out,
int bytesPerLine) |
Create a BASE64 encoder that encodes the specified output stream.
|
Modifier and Type | Method | Description |
---|---|---|
void |
close() |
Forces any buffered output bytes to be encoded out to the stream
and closes this output stream
|
static byte[] |
encode(byte[] inbuf) |
Base64 encode a byte array.
|
void |
flush() |
Flushes this output stream and forces any buffered output bytes
to be encoded out to the stream.
|
void |
write(byte[] b) |
Encodes
b.length bytes to this output stream. |
void |
write(byte[] b,
int off,
int len) |
Encodes
len bytes from the specified
byte array starting at offset off to
this output stream. |
void |
write(int c) |
Encodes the specified
byte to this output stream. |

out
- the output streambytesPerLine
- number of bytes per line. The encoder inserts
a CRLF sequence after the specified number of bytes,
unless bytesPerLine is Integer.MAX_VALUE, in which
case no CRLF is inserted. bytesPerLine is rounded
down to a multiple of 4.public BASE64EncoderStream(java.io.OutputStream out)
