java.lang.Objectjava.io.OutputStream
org.apache.http.impl.io.ChunkedOutputStream
public class ChunkedOutputStream
Implements chunked transfer coding. The content is sent in small chunks. Entities transferred using this output stream can be of unlimited length. Writes are buffered to an internal buffer (2048 default size).
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.
Constructor Summary | |
---|---|
ChunkedOutputStream(SessionOutputBuffer out)
Wraps a session output buffer and chunks the output. |
|
ChunkedOutputStream(SessionOutputBuffer out,
int bufferSize)
Wraps a session output buffer and chunk-encodes the output. |
Method Summary | |
---|---|
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,
int off,
int len)
Writes the cache and bufferToAppend to the underlying stream as one large chunk |
void |
write(byte[] b)
Writes the array. |
void |
write(byte[] src,
int off,
int len)
Writes the array. |
void |
write(int b)
|
protected void |
writeClosingChunk()
