Method Detail

getQualifiers

public java.util.Set<java.lang.annotation.Annotation> getQualifiers()

Returns the bean's binding types

Specified by:

getQualifiers in interface Bean<T>

getStereotypes

public java.util.Set<java.lang.Class<? extends java.lang.annotation.Annotation>> getStereotypes()

Returns the bean's deployment type

Specified by:

getStereotypes in interface Bean<T>

getName

public java.lang.String getName()

Returns the bean's name or null if the bean does not have a primary name.

Specified by:

getName in interface Bean<T>

isNullable

public boolean isNullable()

Returns true if the bean can be null

Specified by:

isAlternative

public boolean isAlternative()

Returns true if the bean can be null

Specified by:

isAlternative in interface Bean<T>

getScope

public java.lang.Class<? extends java.lang.annotation.Annotation> getScope()

create

public T create(CreationalContext<T> creationalContext)

Description copied from interface: Contextual

Creates a new instance for the Contextual's type. If the instance already exists in the CreationalContext, create will return it instead of creating a new instance.

1. create an instance of the bean
2. create interceptor and decorator stacks
3. inject dependencies
4. set any XML-configured values
5. call @PostConstruct

Specified by:

create in interface Contextual<T>

Parameters:

creationalContext - the creation context used to support circular references.

Returns:

the new instance

getInjectionPoints

public java.util.Set<InjectionPoint> getInjectionPoints()

Returns the set of injection points, for validation.

Specified by:

getInjectionPoints in interface Bean<T>
