Class AsyncHttpRequestRetryExec
- All Implemented Interfaces:
AsyncExecChainHandler
HttpRequestRetryStrategy.getRetryInterval(HttpResponse, int, org.apache.hc.core5.http.protocol.HttpContext)
.
Further responsibilities such as communication with the opposite endpoint is delegated to the next executor in the request execution chain.
If this handler is active, pay particular attention to the placement
of other handlers within the handler chain relative to the retry handler.
Use ChainElement.RETRY
as name when referring to this handler.
If a custom handler is placed before the retry handler, the handler will see the initial request and the final outcome after the last retry. Elapsed time will account for any delays imposed by the retry handler.
A custom handler which is placed after the retry handler will be invoked for each individual retry. Elapsed time will measure each individual http request, without the delay imposed by the retry handler.

execute
public void execute(org.apache.hc.core5.http.HttpRequest request, org.apache.hc.core5.http.nio.AsyncEntityProducer entityProducer, AsyncExecChain.Scope scope, AsyncExecChain chain, AsyncExecCallback asyncExecCallback) throws org.apache.hc.core5.http.HttpException, IOException 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:
execute
in interfaceAsyncExecChainHandler
- Parameters:
request
- the actual request.entityProducer
- the request entity producer ornull
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:
