Class Overview

A Base64Harder.OutputStream will write data to another java.io.OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.

Public Constructors

public Base64Harder.OutputStream (OutputStream out)

Constructs a Base64Harder.OutputStream in ENCODE mode.

Parameters
out the java.io.OutputStream to which data will be written.

public Base64Harder.OutputStream (OutputStream out, int options)

Constructs a Base64Harder.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 Base64Harder.OutputStream( out, Base64Harder.ENCODE )

Parameters
out the java.io.OutputStream to which data will be written.
options Specified options.

Public Methods

public void close ()

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

Throws
IOException

public void flushBase64 ()

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

Throws
IOException

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.

public void suspendEncoding ()

Suspends encoding of the stream. May be helpful if you need to embed a piece of base640-encoded data in a stream.

Throws
IOException

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

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

Parameters
theBytes array from which to read bytes
off offset for array
len max number of bytes to read into array
Throws
IOException

public void write (int theByte)

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.

Parameters
theByte the byte to write
Throws
IOException
