Class DefaultConnectingIOReactor

java.lang.Object

org.apache.hc.core5.reactor.AbstractIOReactorBase

org.apache.hc.core5.reactor.DefaultConnectingIOReactor

All Implemented Interfaces:

Closeable, AutoCloseable, ModalCloseable, ConnectionInitiator, IOReactor, IOReactorService

public class DefaultConnectingIOReactor
extends AbstractIOReactorBase

Multi-core I/O reactor that can act as ConnectionInitiator Internally this I/O reactor distributes newly created I/O session equally across multiple I/O worker threads for a more optimal resource utilization and a better I/O performance. Usually it is recommended to have one worker I/O reactor per physical CPU core.

Since:

4.0

Method Details

start

public void start()

Description copied from interface: IOReactorService

Starts I/O reactor.

getStatus

public IOReactorStatus getStatus()

Description copied from interface: IOReactor

Returns the current status of the reactor.

Returns:

reactor status.

getWorkerSelector

IOWorkers.Selector getWorkerSelector()

Specified by:

getWorkerSelector in class AbstractIOReactorBase

initiateShutdown

public void initiateShutdown()

Description copied from interface: IOReactor

Initiates shutdown of the reactor without blocking. The reactor is expected to terminate all active connections, to shut down itself and to release system resources it currently holds

awaitShutdown

public void awaitShutdown(TimeValue waitTime)
                   throws InterruptedException

Description copied from interface: IOReactor

Blocks for the given period of time in milliseconds awaiting the completion of the reactor shutdown.

Parameters:

waitTime - wait time.

Throws:

InterruptedException

close

public void close(CloseMode closeMode)

Description copied from interface: IOReactor

Shuts down the I/O reactor either gracefully or immediately. During graceful shutdown individual I/O sessions should be informed about imminent termination and be given a grace period to complete the ongoing I/O sessions. During immediate shutdown all ongoing I/O sessions get aborted immediately.

Parameters:

closeMode - How to close the receiver.

close

public void close()
           throws IOException

Throws:

IOException
