Constructor Detail

• Base64.Base64OutputStream

  @InterfaceAudience.Private
  @InterfaceStability.Stable
  public Base64.Base64OutputStream(OutputStream out,
                                                                               int options)

  Constructs a Base64.Base64OutputStream 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.Base64OutputStream( out, Base64.ENCODE )

  Parameters:

  out - the OutputStream to which data will be written.

  options - Specified options.

  Since:

  1.3

Method Detail

• write

  public void write(int theByte)
             throws 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.

  Overrides:

  write in class FilterOutputStream

  Parameters:

  theByte - the byte to write

  Throws:

  IOException

  Since:

  1.3

• write

  public void write(byte[] theBytes,
           int off,
           int len)
             throws IOException

  Calls write(int) repeatedly until len bytes are written.

  Overrides:

  write in class FilterOutputStream

  Parameters:

  theBytes - array from which to read bytes

  off - offset for array

  len - max number of bytes to read into array

  Throws:

  IOException

  Since:

  1.3

• flushBase64

  public void flushBase64()
                   throws IOException

  Method added by PHIL. [Thanks, PHIL. -Rob] This pads the buffer without closing the stream.

  Throws:

  IOException - e

• close

  public void close()
             throws IOException

  Flushes and closes (I think, in the superclass) the stream.

  Specified by:

  close in interface Closeable

  Specified by:

  close in interface AutoCloseable

  Overrides:

  close in class FilterOutputStream

  Throws:

  IOException
