      Modifier and Type Method Description
      void endStream​(java.util.List<? extends Header> trailers)
      Terminates the underlying data stream and optionally writes a closing sequence with the given trailers.
      void requestOutput()
      Signals intent by the data producer to produce more data.
      int write​(java.nio.ByteBuffer src)
      Writes data from the buffer through this channel into the underlying byte stream.
    • Method Detail

      • requestOutput

        void requestOutput()
        Signals intent by the data producer to produce more data. Once the channel is able to accept data its handler is expected to trigger an event to notify the data producer.
      • write

        int write​(java.nio.ByteBuffer src)
           throws java.io.IOException
        Writes data from the buffer through this channel into the underlying byte stream. If the underlying byte stream is temporarily unable to accept more data it can return zero to indicate that no data could be written to the data stream. The data producer can choose to call requestOutput() to signal its intent to produce more data.
        Specified by:
        write in interface StreamChannel<java.nio.ByteBuffer>
        Parameters:
        src - source of data
        Returns:
        The number of bytes written, possibly zero
        Throws:
        java.io.IOException
      • endStream

        void endStream​(java.util.List<? extends Header> trailers)
                throws java.io.IOException
        Terminates the underlying data stream and optionally writes a closing sequence with the given trailers.

        Please note that some data streams may not support trailers and may silently ignore the trailers parameter.

        Throws:
        java.io.IOException
