Method Detail

sendRequest

public void sendRequest(RequestChannel requestChannel,
                        HttpContext httpContext)
                 throws HttpException,
                        java.io.IOException

Description copied from interface: AsyncRequestProducer

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

Specified by:

sendRequest in interface AsyncRequestProducer

Parameters:

requestChannel - the request channel capable to accepting a request message.

httpContext - the actual execution context.

Throws:

HttpException

java.io.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 java.io.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:

java.io.IOException

isRepeatable

public boolean isRepeatable()

Description copied from interface: AsyncRequestProducer

Determines whether the producer can consistently produce the same content after invocation of ResourceHolder.releaseResources().

Specified by:

isRepeatable in interface AsyncRequestProducer

failed

public void failed(java.lang.Exception cause)

Description copied from interface: AsyncRequestProducer

Triggered to signal a failure in data generation.

Specified by:

failed in interface AsyncRequestProducer

Parameters:

cause - the cause of the failure.

releaseResources

public void releaseResources()

Specified by:

releaseResources in interface ResourceHolder
