java.lang.Objectorg.jboss.netty.handler.stream.ChunkedNioStream
public class ChunkedNioStream
A 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 Summary | |
---|---|
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. |
Method Summary | |

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()

true
if and only if there is any data left in the
stream. Please note that false
does not necessarily mean that
the stream has reached at its end. In a slow stream, the next chunk
might be unavailable just momentarily.

ChannelBuffer
, 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.
