public class EventLoopGroupExtension
extends AbstractAllOrEachExtension

An Extension that provides an EventLoopGroup. For example:

 > public class MyTest {
 >     @RegisterExtension
 >     public static final EventLoopGroupExtension eventLoopGroup = new EventLoopGroupExtension(4);
 >
 >     @Test
 >     public void test() {
 >         ClientFactory f = ClientFactory.builder()
 >                                        .workerGroup(eventLoopGroup.get())
 >                                        .build();
 >         ...
 >     }
 > }

Constructor Details

EventLoopGroupExtension

public EventLoopGroupExtension(int numThreads)

Creates a new Extension that provides an EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

EventLoopGroupExtension

public EventLoopGroupExtension(int numThreads,
 boolean useDaemonThreads)

Creates a new Extension that provides an EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

useDaemonThreads - whether to create daemon threads or not

EventLoopGroupExtension

EventLoopGroupExtension

public EventLoopGroupExtension(int numThreads,
 String threadNamePrefix,
 boolean useDaemonThreads)

Creates a new Extension that provides an EventLoopGroup.

Parameters:

numThreads - the number of event loop threads

threadNamePrefix - the prefix of thread names

Method Details

get

public EventLoopGroup get()

Returns the EventLoopGroup.

before

public void before(ExtensionContext context)
            throws Exception

Description copied from class: AbstractAllOrEachExtension

A method that should be run at the beginning of a test lifecycle. If AbstractAllOrEachExtension.runForEachTest() returns false, this is run once before all tests, otherwise it is run before each test method.

Specified by:

before in class AbstractAllOrEachExtension

Throws:

Exception

after

public void after(ExtensionContext context)
           throws Exception

Shuts down all threads created by this Extension asynchronously. Call rule.get().shutdownGracefully().sync() if you want to wait for complete termination.
