public class AsyncEntityProducerWrapper
extends Object
implements AsyncEntityProducer
Base class for wrapping entity producers that delegates all calls to the wrapped producer.

available
public int available()Description copied from interface:AsyncDataProducer
Returns the number of bytes immediately available for output. This method can be used as a hint to control output events of the underlying I/O session.- Specified by:
available
in interfaceAsyncDataProducer
- Returns:
- the number of bytes immediately available for output
-
produce
Description copied from interface:AsyncDataProducer

produce
in interfaceAsyncDataProducer
- Parameters:
channel
- the data channel capable to accepting more data.- Throws:
IOException
-
failed
Description copied from interface:AsyncEntityProducer
Triggered to signal a failure in data generation.- Specified by:
failed
in interfaceAsyncEntityProducer
- Parameters:
cause
- the cause of the failure.
