Package org.apache.hc.client5.http.classic

Interface ExecRuntime

All Known Implementing Classes:

InternalExecRuntime

@Internal
public interface ExecRuntime

Execution runtime that provides access to the underlying connection endpoint and helps manager its life cycle.

This interface is considered internal and generally ought not be used or accessed by custom request exec handlers.

Since:

5.0

void	upgradeTls(HttpClientContext context)	Upgrades transport security of the active connection by using the TLS security protocol.

Method Detail

isExecutionAborted

boolean isExecutionAborted()

Determines of the request execution has been aborted.

Returns:

true if the request execution has been acquired, false otherwise.

isEndpointAcquired

boolean isEndpointAcquired()

Determines of a connection endpoint has been acquired.

Returns:

true if an endpoint has been acquired, false otherwise.

acquireEndpoint

void acquireEndpoint(java.lang.String id,
                     HttpRoute route,
                     java.lang.Object state,
                     HttpClientContext context)
              throws java.io.IOException

Acquires a connection endpoint. Endpoints can leased from a pool or unconnected new endpoint can be created.

Parameters:

id - unique operation ID or null.

route - the connection route.

state - the expected connection state. May be null if connection can be state-less or its state is irrelevant.

context - the execution context.

Throws:

java.io.IOException

releaseEndpoint

void releaseEndpoint()

Releases the acquired endpoint potentially making it available for re-use.

discardEndpoint

void discardEndpoint()

Shuts down and discards the acquired endpoint.

isEndpointConnected

boolean isEndpointConnected()

Determines of there the endpoint is connected to the initial hop (connection target in case of a direct route or to the first proxy hop in case of a route via a proxy or multiple proxies).

Returns:

true if the endpoint is connected, false otherwise.

disconnectEndpoint

void disconnectEndpoint()
                 throws java.io.IOException

Disconnects the local endpoint from the initial hop in the connection route.

Throws:

java.io.IOException

connectEndpoint

void connectEndpoint(HttpClientContext context)
              throws java.io.IOException

Connect the local endpoint to the initial hop (connection target in case of a direct route or to the first proxy hop in case of a route via a proxy or multiple proxies).

Parameters:

context - the execution context.

Throws:

java.io.IOException

upgradeTls

void upgradeTls(HttpClientContext context)
         throws java.io.IOException

Upgrades transport security of the active connection by using the TLS security protocol.

Parameters:

context - the execution context.

Throws:

java.io.IOException

execute

org.apache.hc.core5.http.ClassicHttpResponse execute(java.lang.String id,
                                                     org.apache.hc.core5.http.ClassicHttpRequest request,
                                                     HttpClientContext context)
                                              throws java.io.IOException,
                                                     org.apache.hc.core5.http.HttpException

Executes HTTP request using the given context.

Parameters:

id - unique operation ID or null.

request - the request message.

context - the execution context.

Throws:

java.io.IOException

org.apache.hc.core5.http.HttpException

isConnectionReusable

boolean isConnectionReusable()

Determines of the connection is considered re-usable.

Returns:

true if the connection is re-usable, false otherwise.

markConnectionReusable

void markConnectionReusable(java.lang.Object state,
                            org.apache.hc.core5.util.TimeValue validityTime)

Marks the connection as potentially re-usable for the given period of time and also marks it as stateful if the state representation is given.

Parameters:

state - the connection state representation or null if stateless.

validityTime - the period of time this connection is valid for.

markConnectionNonReusable

void markConnectionNonReusable()

Marks the connection as non re-usable.

fork

ExecRuntime fork(org.apache.hc.core5.concurrent.CancellableDependency cancellableAware)

Forks this runtime for parallel execution.

Returns:

another runtime with the same configuration.
