ca.phon.util.Base64.OutputStream
All Implemented Interfaces:

Enclosing class:
Base64
public static class Base64.OutputStream extends FilterOutputStream
A
invalid @link 
Base64#OutputStream
will write data to another OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.

1.3

      public OutputStream(OutputStream out)
      Constructs a
      invalid @link 
      Base64#OutputStream
      in ENCODE mode.
      Parameters:
      out - the OutputStream to which data will be written.
      Since:
      1.3

    • OutputStream

      public OutputStream(OutputStream out, int options)
      Constructs a
      invalid @link 
      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 )

      Parameters:
      out - the OutputStream to which data will be written.
      options - Specified options.

  • Method Details

    • 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

    • close

      public void close() throws IOException
      Flushes and closes (I think, in the superclass) the stream.
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Closeable
      Overrides:
      close in class FilterOutputStream
      Throws:
      IOException
      Since:
      1.3

    • suspendEncoding

      public void suspendEncoding() throws IOException
      Suspends encoding of the stream. May be helpful if you need to embed a piece of base640-encoded data in a stream.
      Throws:
      IOException
      Since:
      1.5.1

    • 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.
      Since:
      1.5.1
