方法详细资料

updateCapacity

void updateCapacity(CapacityChannel capacityChannel)
             throws IOException

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.

参数:

capacityChannel - the channel for capacity updates.

抛出:

IOException

consume

void consume(ByteBuffer src)
      throws IOException

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.

参数:

src - data source.

抛出:

IOException

streamEnd

void streamEnd(List<? extends Header> trailers)
        throws HttpException,
               IOException

Triggered to signal termination of the data stream.

参数:

trailers - data stream trailers.

抛出:

HttpException

IOException
