Method Detail

beanInstance

public <T> T beanInstance(Class<T> beanType,
                          Annotation... beanQualifiers)

Description copied from interface: BeanContainer

Resolves a bean instance for given bean type and qualifiers.

Performs standard CDI resolution meaning it either returns a bean instance or throws a corresponding exception if the dependency is either unsatisfied or ambiguous.

Specified by:

beanInstance in interface BeanContainer

Parameters:

beanType - type of the bean

beanQualifiers - bean qualifiers

Returns:

a bean instance; never null

beanInstanceFactory

public <T> BeanContainer.Factory<T> beanInstanceFactory(Class<T> type,
                                                        Annotation... qualifiers)

Description copied from interface: BeanContainer

Returns an instance factory for given bean type and qualifiers.

This method performs CDI ambiguous dependency resolution and throws and exception if there are two or more beans with given type and qualifiers.

If no matching bean is found, uses a default fallback factory that will attempt to instantiate a non-CDI object of the given class via no-args constructor.

If you need custom factory behavior, take a look at BeanContainer.beanInstanceFactory(Supplier, Class, Annotation...)

Specified by:

beanInstanceFactory in interface BeanContainer

Parameters:

type - bean type

qualifiers - bean qualifiers

Returns:

a bean instance factory, never null

beanInstanceFactory

public <T> BeanContainer.Factory<T> beanInstanceFactory(Supplier<BeanContainer.Factory<T>> fallbackSupplier,
                                                        Class<T> type,
                                                        Annotation... qualifiers)

Description copied from interface: BeanContainer

Returns an instance factory for given bean type and qualifiers.

This method performs CDI ambiguous dependency resolution and throws and exception if there are two or more beans with given type and qualifiers.

If no matching bean is found, delegates all calls to the supplied factory fallback.

Specified by:

beanInstanceFactory in interface BeanContainer

Parameters:

fallbackSupplier - supplier to delegate to if there is no bean

type - bean type

qualifiers - bean qualifiers

Returns:

a bean instance factory, never null

requestContext

public ManagedContext requestContext()

Description copied from interface: BeanContainer

 ManagedContext requestContext = beanContainer.requestContext();
 if (requestContext.isActive()) {
     // Perform action
 } else {
     try {
         requestContext.activate();
         // Perform action
     } finally {
         requestContext.terminate();
     }
 }
 

Specified by:

requestContext in interface BeanContainer

Returns:

the context for RequestScoped
