Class ChunkedStream

    • Constructor Detail

      • ChunkedStream

        public ChunkedStream​(InputStream in)
        Creates a new instance that fetches data from the specified stream.
      • ChunkedStream

        public ChunkedStream​(InputStream in,
                             int chunkSize)
        Creates a new instance that fetches data from the specified stream.
        Parameters:
        chunkSize - the number of bytes to fetch on each nextChunk() call
    • Method Detail

      • getTransferredBytes

        public long getTransferredBytes()
        Returns the number of transferred bytes.
      • hasNextChunk

        public boolean hasNextChunk()
                             throws Exception
        Description copied from interface: ChunkedInput
        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.

        hasNextChunk in interface ChunkedInput
        Throws:
        Exception
      • isEndOfInput

        public boolean isEndOfInput()
                             throws Exception
        Description copied from interface: ChunkedInput
        Return true if and only if there is no data left in the stream and the stream has reached at its end.
        Specified by:
        isEndOfInput in interface ChunkedInput
        Throws:
        Exception
      • nextChunk

        public Object nextChunk()
                         throws Exception
        Description copied from interface: ChunkedInput
        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 ChunkedInput.isEndOfInput() call must return false.
        Specified by:
        nextChunk in interface ChunkedInput
        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
