All Implemented Interfaces:

AsyncExecChainHandler

@Contract(threading=STATELESS)
@Internal
public final class AsyncProtocolExec
extends Object
implements AsyncExecChainHandler

Request execution handler in the asynchronous request execution chain that is responsible for implementation of HTTP specification requirements.

Further responsibilities such as communication with the opposite endpoint is delegated to the next executor in the request execution chain.

Description copied from interface: AsyncExecChainHandler

Executes the actual HTTP request. The handler can choose to return a response message immediately inside the call or asynchronously at some later point or delegate request execution to the next element in the execution chain.

Specified by:

Parameters:

userRequest - the actual request.

entityProducer - the request entity producer or null if the request does not enclose an entity.

scope - the execution scope .

chain - the next element in the request execution chain.

asyncExecCallback - the execution callback.

Throws:

org.apache.hc.core5.http.HttpException - If a protocol error occurs.

IOException - If an I/O error occurs.
