Class Base64.OutputStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

org.nuxeo.client.util.Base64.OutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

Enclosing class:

Base64

public static class Base64.OutputStream
extends FilterOutputStream

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

1.3

Method Summary

Modifier and Type	Method and Description
void	close() Flushes and closes (I think, in the superclass) the stream.

Constructor Detail

OutputStream

public OutputStream(OutputStream out)

Constructs a Base64.OutputStream in ENCODE mode.

Parameters:

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

Since:

1.3

OutputStream

public OutputStream(OutputStream out,
                    int options)

Constructs a 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 java.io.OutputStream to which data will be written.

options - Specified options.

Since:

1.3

See Also:

Base64.ENCODE, Base64.DECODE, Base64.DONT_BREAK_LINES

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

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

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
