Weld (Weld SE (Uber Jar) 2.3.2.Final API)

java.lang.Object
- org.jboss.weld.environment.se.Weld

All Implemented Interfaces:

ContainerInstanceFactory
```
@Vetoed
public class Weld
extends Object
implements 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.

  - initialize
```
public WeldContainer initialize()
```
    Bootstraps a new Weld SE container with the current containerId.
    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.
    
    Specified by:
    
    initialize in interface ContainerInstanceFactory
    
    Returns:
    
    the Weld container
    
    See Also:
    
    enableDiscovery(), WeldContainer.shutdown()
  - shutdown
```
public void shutdown()
```
    Shuts down all the containers initialized by this builder.
  - setClassLoader
```
public Weld setClassLoader(ClassLoader classLoader)
```
    Set a ClassLoader. The given ClassLoader will be scanned automatically for bean archives if scanning is enabled.
    
    Parameters:
    
    classLoader -
    
    Returns:
    
    self
  - setResourceLoader
```
public Weld setResourceLoader(ResourceLoader resourceLoader)
```
    Set a ResourceLoader used to scan the application for bean archives. If you only want to use a specific ClassLoader for scanning, use setClassLoader(ClassLoader) instead.
    
    Parameters:
    
    resourceLoader -
    
    Returns:
    
    self
    
    See Also:
    
    isDiscoveryEnabled()
  - createDeployment
```
protected Deployment createDeployment(ResourceLoader resourceLoader,
                                      CDI11Bootstrap bootstrap)
```
    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();
 
```
    Parameters:
    
    resourceLoader -
    
    bootstrap -
  - getInstanceByType
```
protected <T> T getInstanceByType(BeanManager manager,
                                  Class<T> type,
                                  Annotation... bindings)
```
    Utility method allowing managed instances of beans to provide entry points for non-managed beans (such as WeldContainer). Should only called once Weld has finished booting.
    
    Parameters:
    
    manager - the BeanManager to use to access the managed instance
    
    type - the type of the Bean
    
    bindings - the bean's qualifiers
    
    Returns:
    
    a managed instance of the bean
    
    Throws:
    
    IllegalArgumentException - if the given type represents a type variable
    
    IllegalArgumentException - if two instances of the same qualifier type are given
    
    IllegalArgumentException - if an instance of an annotation that is not a qualifier type is given
    
    UnsatisfiedResolutionException - if no beans can be resolved * @throws AmbiguousResolutionException if the ambiguous dependency resolution rules fail
    
    IllegalArgumentException - if the given type is not a bean type of the given bean
