Class Weld

java.lang.Object

org.jboss.weld.environment.se.Weld

public class Weld
extends Object

The preferred method of booting Weld SE.

Typical usage of this API looks like this:

 Weld weld = new Weld();
 WeldContainer container = weld.initialize();
 container.instance().select(Foo.class).get();
 container.event().select(Bar.class).fire(new Bar());
 weld.shutdown();

Method Detail

addExtension

public void addExtension(Extension extension)

Add extension explicitly.

Parameters:

extension - an extension

initialize

public WeldContainer initialize()

Boots Weld and creates and returns a WeldContainer instance, through which beans and events can be accessed.

Returns:

weld container

createDeployment

protected Deployment createDeployment(ResourceLoader resourceLoader,
                          Bootstrap bootstrap)

Extensions to Weld SE can subclass and override this method to customise 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()
    {
       Deployment deployment = super.createDeployment();
       deployment.getServices().add(ResourceLoader.class, new MyResourceLoader());
       return deployment;
    }
 }
 

This could then be used as normal:

 WeldContainer container = new MyWeld().initialize();
 

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

shutdown

public void shutdown()

Shuts down Weld.
