public int available()

Implements org.apache.hc.core5.http.nio.AsyncDataProducer.available.

Doc from org.apache.hc.core5.http.nio.AsyncDataProducer.available.

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.

consumeback to summary
public void consume(final ByteBuffer src) throws IOException

Implements org.apache.hc.core5.http.nio.AsyncDataConsumer.consume.

Doc from org.apache.hc.core5.http.nio.AsyncDataConsumer.consume.

Triggered to pass incoming data to the data consumer. The consumer must consume the entire content of the data buffer. The consumer must stop incrementing its capacity on the capacity channel if it is unable to accept more data. Once the data consumer has handled accumulated data or allocated more intermediate storage it can update its capacity information on the capacity channel.

Parameters
src:ByteBuffer

data source.

Implements org.apache.hc.core5.http.nio.AsyncDataExchangeHandler.failed.

Doc from org.apache.hc.core5.http.nio.AsyncDataExchangeHandler.failed.

Triggered to signal a failure in data processing.

Parameters
cause:Exception

the cause of the failure.

Implements org.apache.hc.core5.http.nio.AsyncServerExchangeHandler.handleRequest.

Doc from org.apache.hc.core5.http.nio.AsyncServerExchangeHandler.handleRequest.

Processes the actual HTTP request. The handler can choose to send response messages immediately inside the call or asynchronously at some later point.

Parameters
request:HttpRequest

the actual request.

entityDetails:EntityDetails

the request entity details or null if the request does not enclose an entity.

responseChannel:ResponseChannel

the response channel.

context:HttpContext

Implements org.apache.hc.core5.http.nio.AsyncDataProducer.produce.

Doc from org.apache.hc.core5.http.nio.AsyncDataProducer.produce.

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.

Parameters
channel:DataStreamChannel

the data channel capable to accepting more data.
