T - entity representation.public abstract class AbstractClassicEntityConsumer<T> extends Object implements AsyncEntityConsumer<T>
AsyncEntityConsumer implementation that acts as a compatibility
 layer for classic InputStream based interfaces. Blocking input
 processing is executed through an Executor.| Constructor and Description |

| Modifier and Type | Method and Description | 
|---|---|
| void | consume(ByteBuffer src)Triggered to pass incoming data to the data consumer. | 
| protected abstract T | consumeData(ContentType contentType,
           InputStream inputStream)Processes entity data from the given stream. | 
| void | failed(Exception cause)Triggered to signal a failure in data processing. | 
| T | getContent()Returns the result of entity processing when it becomes available or  nullif the entity is still being received. | 
| Exception | getException() | 
| void | releaseResources() | 
| void | streamEnd(List<? extends Header> trailers)Triggered to signal termination of the data stream. | 
| void | streamStart(EntityDetails entityDetails,
           FutureCallback<T> resultCallback)Signals beginning of an incoming request entity stream. | 
| void | updateCapacity(CapacityChannel capacityChannel)Triggered to signal ability of the underlying data stream to receive
 data capacity update. |
