produceResponse
public void produceResponse(ResponseChannel channel, HttpContext httpContext) throws HttpException, IOException Description copied from interface:AsyncPushProducer
Triggered to signal the ability of the underlying response channel to accept response messages. The data producer can choose to send a final response message immediately inside the call or asynchronously at some later point. The final response can be preceded by a number of intermediate messages.- Specified by:
produceResponse
in interfaceAsyncPushProducer
- Parameters:
channel
- the response channel capable to accepting response messages.httpContext
- the actual execution context.- Throws:
HttpException
IOException
-
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
Triggered to signal the ability of the underlying data channel to accept more data. The data producer can choose to write data immediately inside the call or asynchronously at some later point.- Specified by:
produce
in interfaceAsyncDataProducer
- Parameters:
channel
- the data channel capable to accepting more data.- Throws:
IOException
-
failed
Description copied from interface:AsyncPushProducer
Triggered to signal a failure in data generation.- Specified by:
failed
in interfaceAsyncPushProducer
- Parameters:
cause
- the cause of the failure.
