boolean	hasNextChunk() Returns true if and only if there is any data left in the stream.

Object	nextChunk() Fetches a chunked data from the stream.

Method Detail

hasNextChunk

boolean hasNextChunk()
                     throws Exception

Returns 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.

Throws:

Exception

nextChunk

Object nextChunk()
                 throws Exception

Fetches a chunked data from the stream. The returned chunk is usually a 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 isEndOfInput() call must return false.

Returns:

the fetched chunk, which is usually ChannelBuffer. 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.

Throws:

Exception

isEndOfInput

boolean isEndOfInput()
                     throws Exception

Return true if and only if there is no data left in the stream and the stream has reached at its end.

Throws:

Exception

close

void close()
           throws Exception

Releases the resources associated with the stream.

Throws:
