public class ChunkedNioStream extends Object implements ChunkedInput
ChunkedInput
that fetches data from a ReadableByteChannel
chunk by chunk. Please note that the ReadableByteChannel
must
operate in blocking mode. Non-blocking mode channels are not supported.Constructor and Description |
---|
ChunkedNioStream(ReadableByteChannel in)
Creates a new instance that fetches data from the specified channel.
|
ChunkedNioStream(ReadableByteChannel in,
int chunkSize)
Creates a new instance that fetches data from the specified channel.

Modifier and Type | Method and Description |
---|---|
void |
close()
Releases the resources associated with the stream.
|
long |
getTransferredBytes()
Returns the number of transferred bytes.
|
boolean |
hasNextChunk()
Returns
true if and only if there is any data left in the
stream. |
boolean |
isEndOfInput()
Return
true if and only if there is no data left in the stream
and the stream has reached at its end. |
Object |
nextChunk()
Fetches a chunked data from the stream.

, but you could extend an existing implementation
to convert the ChannelBuffer
into a different type that your
handler or encoder understands. Once this method returns the last chunk
and thus the stream has reached at its end, any subsequent ChunkedInput.isEndOfInput()
call must return false

null
if there is no data left in the stream.
Please note that null
does not necessarily mean that the
stream has reached at its end. In a slow stream, the next chunk
might be unavailable just momentarily.Exception
