Method Details

sendResponse

public void sendResponse(ResponseChannel responseChannel,
 HttpContext httpContext)
                  throws HttpException,
IOException

Description copied from interface: AsyncResponseProducer

Triggered to signal the ability of the underlying response channel to accept response messages. The data producer can choose to send response messages immediately inside the call or asynchronously at some later point.

Specified by:

sendResponse in interface AsyncResponseProducer

Parameters:

responseChannel - 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 interface AsyncDataProducer

Returns:

the number of bytes immediately available for output

produce

public void produce(DataStreamChannel channel)
             throws IOException

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 interface AsyncDataProducer

Parameters:

channel - the data channel capable to accepting more data.

Throws:

IOException

failed

public void failed(Exception cause)

Description copied from interface: AsyncResponseProducer

Triggered to signal a failure in data generation.

Specified by:

failed in interface AsyncResponseProducer

Parameters:

cause - the cause of the failure.

releaseResources

public void releaseResources()

Specified by:

releaseResources in interface ResourceHolder
