public class ChunkedOutputStream extends OutputStream
Note that this class NEVER closes the underlying stream, even when close gets called. Instead, the stream will be marked as closed and no further output will be permitted.

void |
close()
Finishes writing to the underlying stream, but does NOT close the underlying stream.
|
void |
finish()
Must be called to ensure the internal cache is flushed and the closing
chunk is written.
|
void |
flush()
Flushes the content buffer and the underlying stream.
|
protected void |
flushCache()
Writes the cache out onto the underlying stream
|
protected void |
flushCacheWithAppend(byte[] bufferToAppend,

Writes the cache and bufferToAppend to the underlying stream
as one large chunk
|
