@Vetoed public class Weld extends Object implements org.jboss.weld.environment.ContainerInstanceFactory
This builder is a preferred method of booting Weld SE container.
Typical usage looks like this:
WeldContainer container = new Weld().initialize(); container.select(Foo.class).get(); container.event().select(Bar.class).fire(new Bar()); container.shutdown();
The WeldContainer implements AutoCloseable:
try (WeldContainer container = new Weld().initialize()) {
container.select(Foo.class).get();
}
By default, the discovery is enabled so that all beans from all discovered bean archives are considered. However, it's possible to define a "synthetic" bean archive, or the set of bean classes and enablement respectively:
WeldContainer container = new Weld().beanClasses(Foo.class, Bar.class).alternatives(Bar.class).initialize()) {
Moreover, it's also possible to disable the discovery completely so that only the "synthetic" bean archive is considered:
WeldContainer container = new Weld().disableDiscovery().beanClasses(Foo.class, Bar.class).initialize()) {
In the same manner, it is possible to explicitly declare interceptors, decorators, extensions and Weld-specific options (such as relaxed construction) using the builder.
Weld builder = new Weld()
.disableDiscovery()
.packages(Main.class, Utils.class)
.interceptors(TransactionalInterceptor.class)
.property("org.jboss.weld.construction.relaxed", true);
WeldContainer container = builder.initialize();
The builder is reusable which means that it's possible to initialize multiple Weld containers with one builder. However, note that containers must have a unique identifier assigned when running multiple Weld instances at the same time.

The container must be shut down properly when an application is stopped. Applications are encouraged to use the try-with-resources statement or invoke
WeldContainer.shutdown() explicitly.
However, a shutdown hook is also registered during initialization so that all running containers are shut down automatically when a program exits or VM
is terminated. This means that it's not necessary to implement the shutdown logic in a class where a main method is used to start the container.initialize in interface org.jboss.weld.environment.ContainerInstanceFactoryenableDiscovery(),

ClassLoader. The given ClassLoader will be scanned automatically for bean archives if scanning is enabled.classLoader - public Weld setResourceLoader(org.jboss.weld.resources.spi.ResourceLoader resourceLoader)
ResourceLoader used to scan the application for bean archives. If you only want to use a specific ClassLoader for scanning, use

Extensions to Weld SE can subclass and override this method to customize the deployment before weld boots up. For example, to add a custom ResourceLoader, you would subclass Weld like so:
public class MyWeld extends Weld {
protected Deployment createDeployment(ResourceLoader resourceLoader, CDI11Bootstrap bootstrap) {
return super.createDeployment(new MyResourceLoader(), bootstrap);
}
}
This could then be used as normal:
WeldContainer container = new MyWeld().initialize();
