Method Detail

executeback to summary
public <T> Future<T> execute(AsyncRequestProducer requestProducer, AsyncResponseConsumer<T> responseConsumer, HandlerFactory<AsyncPushConsumer> pushHandlerFactory, HttpContext context, FutureCallback<T> callback)

Initiates asynchronous HTTP request execution using the given context.

The request producer passed to this method will be used to generate a request message and stream out its content without buffering it in memory. The response consumer passed to this method will be used to process a response message without buffering its content in memory.

Please note it may be unsafe to interact with the context instance while the request is still being executed.

Parameters
<T>
the result type of request execution.
requestProducer:AsyncRequestProducer

request producer callback.

responseConsumer:AsyncResponseConsumer<T>

response consumer callback.

pushHandlerFactory:HandlerFactory<AsyncPushConsumer>

the push handler factory. Optional and may be null.

context:HttpContext

HTTP context. Optional and may be null.

callback:FutureCallback<T>

future callback. Optional and may be null.

Returns:Future<T>
