      • updateCapacity

        public void updateCapacity​(CapacityChannel capacityChannel)
                            throws java.io.IOException
        Description copied from interface: AsyncDataConsumer
        Triggered to signal ability of the underlying data stream to receive data capacity update. The data consumer can choose to write data immediately inside the call or asynchronously at some later point.
        Specified by:
        updateCapacity in interface AsyncDataConsumer
        Parameters:
        capacityChannel - the channel for capacity updates.
        Throws:
        java.io.IOException
      • consume

        public void consume​(java.nio.ByteBuffer src)
                     throws java.io.IOException
        Description copied from interface: AsyncDataConsumer
        Triggered to pass incoming data to the data consumer. The consumer must consume the entire content of the data buffer. The consumer must stop incrementing its capacity on the capacity channel if it is unable to accept more data. Once the data consumer has handled accumulated data or allocated more intermediate storage it can update its capacity information on the capacity channel.
        Specified by:
        consume in interface AsyncDataConsumer
        Parameters:
        src - data source.
        Throws:
        java.io.IOException
      • failed

        public void failed​(java.lang.Exception cause)
        Description copied from interface: AsyncEntityConsumer
        Triggered to signal a failure in data processing.
        Specified by:
        failed in interface AsyncEntityConsumer<T>
        Parameters:
        cause - the cause of the failure.
      • getContent

        public T getContent()
        Description copied from interface: AsyncEntityConsumer
        Returns the result of entity processing when it becomes available or null if the entity is still being received.
        Specified by:
        getContent in interface AsyncEntityConsumer<T>
        Returns:
        the response processing result.
      • getTrailers

        public java.util.List<Header> getTrailers()
        List of trailers sent with the data stream.
        Returns:
        the list of trailers sent with the data stream
      • getDigest

        public byte[] getDigest()
        Returns digest hash.
        Returns:
        the digest hash value.
