Class Base64.OutputStream
java.io.FilterOutputStream
jonelo.sugar.util.Base64.OutputStream
- Base64
public static class Base64.OutputStream
extends java.io.FilterOutputStream
A Base64.OutputStream
will write data to another
java.io.OutputStream, given in the constructor,
and encode/decode to/from Base64 notation on the fly.
OutputStream(java.io.OutputStream out) - Constructs a
Base64.OutputStream in ENCODE mode.
|
OutputStream(java.io.OutputStream out, int options) - Constructs a
Base64.OutputStream in
either ENCODE or DECODE mode.
|
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.

OutputStream
public OutputStream(java.io.OutputStream out)
Constructs a Base64.OutputStream
in ENCODE mode.
out
- the java.io.OutputStream to which data will be written.
OutputStream
public OutputStream(java.io.OutputStream out,
int options)
Constructs a
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 )
out
- the java.io.OutputStream to which data will be written.options
- Specified options.
Base64.ENCODE
, Base64.DECODE
, Base64.DONT_BREAK_LINES
close
public void close()
throws java.io.IOException
Flushes and closes (I think, in the superclass) the stream.
flushBase64
public void flushBase64()
throws java.io.IOException
Method added by PHIL. [Thanks, PHIL. -Rob]
This pads the buffer without closing the stream.
resumeEncoding
public void resumeEncoding()
Resumes encoding of the stream.
May be helpful if you need to embed a piece of
base640-encoded data in a stream.
suspendEncoding
public void suspendEncoding()
throws java.io.IOException
Suspends encoding of the stream.
May be helpful if you need to embed a piece of
base640-encoded data in a stream.
write
public void write(byte[] theBytes,
int off,
int len)
throws java.io.IOException
Calls
write(int)
repeatedly until
len
bytes are written.
theBytes
- array from which to read bytesoff
- offset for arraylen
- max number of bytes to read into array
write
public void write(int theByte)
throws java.io.IOException
Writes the byte to the output stream after
converting to/from Base64 notation.
When encoding, bytes are buffered three
at a time before the output stream actually
gets a write() call.
When decoding, bytes are buffered four
at a time.
theByte
- the byte to write
