Public constructors
Base64OutputStream
public Base64OutputStream (OutputStream out,
int flags)
Performs Base64 encoding on the data written to the stream,
writing the encoded data to another OutputStream.
Parameters |
out |
OutputStream : the OutputStream to write the encoded data to |
flags |
int : bit flags for controlling the encoder; see the
constants in Base64 |
Public methods
close
public void close ()
Closes this output stream and releases any system resources
associated with the stream.
When not already closed, the close
method of FilterOutputStream
calls its flush
method, and then
calls the close
method of its underlying output stream.
write
public void write (byte[] b,
int off,
int len)
Writes 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 output stream with the same arguments. Subclasses
of FilterOutputStream
should provide a more efficient
implementation of this method.
Parameters |
b |
byte : the data. |
off |
int : the start offset in the data. |
len |
int : the number of bytes to write. |
write
public void write (int b)
Writes the specified 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
.
Parameters |
b |
int : the byte . |
