Interface ExecChainHandler

All Known Implementing Classes:

BackoffStrategyExec, ConnectExec, ContentCompressionExec, HttpRequestRetryExec, MainClientExec, ProtocolExec, RedirectExec

@Contract(threading=STATELESS)
public interface ExecChainHandler

Abstract request execution handler in a classic client side request execution chain. Handlers can either be a decorator around another element that implements a cross cutting aspect or a self-contained executor capable of producing a response for the given request.

Important: please note it is required for decorators that implement post execution aspects or response post-processing of any sort to release resources associated with the response by calling Closeable.close() methods in case of an I/O, protocol or runtime exception, or in case the response is not propagated to the caller.
