Examples with ExecutorServiceProvider org.glassfish.jersey.spi.ExecutorServiceProvider used on opensource projects

Example 1 with ExecutorServiceProvider

use of org.glassfish.jersey.spi.ExecutorServiceProvider in project jersey by jersey.

the class ExecutorProviders method createInjectionBindings.

/**
     * Create qualified {@link java.util.concurrent.ExecutorService} and {@link java.util.concurrent.ScheduledExecutorService}
     * injection bindings based on the registered providers implementing the
     * {@link org.glassfish.jersey.spi.ExecutorServiceProvider} and/or
     * {@link org.glassfish.jersey.spi.ScheduledExecutorServiceProvider} SPI.
     * <p>
     * This method supports creation of qualified injection bindings based on custom
     * {@link javax.inject.Qualifier qualifier annotations} attached to the registered provider implementation classes
     * as well as named injection bindings based on the {@link javax.inject.Named} qualifier annotation attached to the
     * registered provider implementation classes.
     * </p>

     * @param injectionManager application's injection manager.

Example 2 with ExecutorServiceProvider

use of org.glassfish.jersey.spi.ExecutorServiceProvider in project dropwizard by dropwizard.

the class DropwizardExecutorProviderTest method shutsDownDisposableExecutorService.

@Test
public void shutsDownDisposableExecutorService() {
    final ExecutorService executor = Executors.newSingleThreadExecutor();
    final ExecutorService disposableExecutor = new DropwizardExecutorProvider.DisposableExecutorService(executor);
    final ExecutorServiceProvider provider = new DropwizardExecutorProvider(disposableExecutor, SHUTDOWN_TIME);
    assertThat(executor.isShutdown()).isFalse();
    provider.dispose(disposableExecutor);
    assertThat(executor.isShutdown()).isTrue();
}

Example 3 with ExecutorServiceProvider

use of org.glassfish.jersey.spi.ExecutorServiceProvider in project dropwizard by dropwizard.

the class DropwizardExecutorProviderTest method doesntShutDownNonDisposableExecutorService.

@Test
public void doesntShutDownNonDisposableExecutorService() {
    final ExecutorService executor = Executors.newSingleThreadExecutor();
    final ExecutorServiceProvider provider = new DropwizardExecutorProvider(executor, SHUTDOWN_TIME);
    assertThat(executor.isShutdown()).isFalse();
    provider.dispose(executor);
    assertThat(executor.isShutdown()).isFalse();
    executor.shutdown();
