Class Base64EncodeStream

java.lang.Object

java.io.OutputStream

org.apache.xmlgraphics.util.io.Base64EncodeStream

All Implemented Interfaces:

Closeable, Flushable

public class Base64EncodeStream
extends OutputStream

This class implements a Base64 Character encoder as specified in RFC1113. Unlike some other encoding schemes there is nothing in this encoding that indicates where a buffer starts or ends. This means that the encoded text will simply start with the first line of encoded text and end with the last line of encoded text.

public Base64EncodeStream(OutputStream out,
                  boolean closeOutOnClose)

Method Detail

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException

flush

public void flush()
           throws IOException

This can't really flush out output since that may generate '=' chars which would indicate the end of the stream. Instead we flush out. You can only be sure all output is writen by closing this stream.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException

write

public void write(int b)
           throws IOException

Specified by:

write in class OutputStream

Throws:

IOException

write

public void write(byte[] data)
           throws IOException

Overrides:

write in class OutputStream

Throws:

IOException

write

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

Overrides:

Throws:

IOException
