Constructor and Description |
---|
OutputStream(OutputStream out)
Constructs a
Base64.OutputStream in ENCODE mode. |
OutputStream(OutputStream out,
int options)
Constructs a
Base64.OutputStream in
either ENCODE or DECODE mode. |
Modifier and Type | Method and Description |
---|---|
void |
close()
Flushes and closes (I think, in the superclass) the stream.
|
void |
flushBase64()
Method added by PHIL.
|
void |
resumeEncoding()
Resumes encoding of the stream.
|
void |
suspendEncoding()
Suspends encoding of the stream.
|
void |
write(byte[] theBytes,
int off,
int len)
Calls
write(int) repeatedly until len
bytes are written. |
void |
write(int theByte)
Writes the byte to the output stream after
converting to/from Base64 notation.

public OutputStream(OutputStream out)
Base64.OutputStream

- the java.io.OutputStream to which data will be written.public OutputStream(OutputStream out, int options)
Base64.OutputStream
in
either ENCODE or DECODE mode.
Valid options:
ENCODE or DECODE: Encode or Decode as data is read. DONT_BREAK_LINES: don't break lines at 76 characters (only meaningful when encoding) Note: Technically, this makes your encoding non-compliant.
Example: new Base64.OutputStream( out, Base64.ENCODE )
