public class MimeOutputStream

extends FilterOutputStream

java.io.FilterOutputStream implementation for Mime base 64. Not incredibly efficient, but it works and is small. All we need to implement are: write(int) flush()

Field Summary

private static int[]	charset Mime character set translation
private static int	pad

Method Detail

write

public void write(int c)
           throws IOException

Write the specified byte, performing mime encoding.

Override this method, since all other write methods call it.

Overrides:

write in class FilterOutputStream

Throws:

IOException - If an I/O error occurs

flush

public void flush()
           throws IOException

Flush the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another character or byte stream, flush it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams. This version does not buffer, but Mime encoding may have some trailing stuff, which needs padding.

Overrides:

flush in class FilterOutputStream

Throws:

IOException - If an I/O error occurs
