Example 16 with Multibinder

use of com.google.inject.multibindings.Multibinder in project druid by druid-io.

the class InitializationTest method testCreateInjectorWithNodeRoleFilterUsingInject_moduleLoaded.

@Test
public void testCreateInjectorWithNodeRoleFilterUsingInject_moduleLoaded() {
    final Set<NodeRole> nodeRoles = ImmutableSet.of(new NodeRole("role1"), new NodeRole("druid"));
    final DruidNode expected = new DruidNode("test-inject", null, false, null, null, true, false);
    Injector startupInjector = GuiceInjectors.makeStartupInjectorWithModules(ImmutableList.of(binder -> {
        Multibinder<NodeRole> selfBinder = Multibinder.newSetBinder(binder, NodeRole.class, Self.class);
        nodeRoles.forEach(nodeRole -> selfBinder.addBinding().toInstance(nodeRole));
    }));
    Injector injector = Initialization.makeInjectorWithModules(nodeRoles, startupInjector, ImmutableList.of((com.google.inject.Module) binder -> JsonConfigProvider.bindInstance(binder, Key.get(DruidNode.class, Self.class), expected), new NodeRolesInjectTestModule()));
