public class Base64OutputStream extends FilterOutputStream
out
Constructor and Description |
---|
Base64OutputStream(OutputStream out,
int flags)
Performs Base64 encoding on the data written to the stream,
writing the encoded data to another OutputStream.
|
Base64OutputStream(OutputStream out,
int flags,
boolean encode)
Performs Base64 encoding or decoding on the data written to the
stream, writing the encoded/decoded data to another
OutputStream.

close()
Closes this output stream and releases any system resources
associated with the stream.

void |
write(byte[] b,
int off,
int len)
Writes
len bytes from the specified
byte array starting at offset off to
this output stream. |

write(int b)
Writes the specified
byte to this output stream. |

byte
to this output stream.
The write
method of FilterOutputStream
calls the write
method of its underlying output stream,
that is, it performs out.write(b).
Implements the abstract write method of OutputStream.

FilterOutputStream
len
bytes from the specified
byte
array starting at offset off
to
this output stream.
The write
method of FilterOutputStream
calls the write
method of one argument on each
byte
to output.
Note that this method does not call the write
method
of its underlying input stream with the same arguments. Subclasses
of FilterOutputStream
should provide a more efficient
implementation of this method.

FilterOutputStream
The close
method of FilterOutputStream
calls its flush
method, and then calls the
close
method of its underlying output stream.
