addInFlightBean

<T> void addInFlightBean(BeanIdentifier beanIdentifier,
                         T instance)

<T> void removeInFlightBean(BeanIdentifier beanIdentifier)

Removes a bean that is in the process of being created. This is used to store references to instances passed to BeanContext.inject(Object)

Type Parameters:

T - THe instance type

Parameters:

beanIdentifier - The bean identifier

getInFlightBean

@Nullable
<T> T getInFlightBean(BeanIdentifier beanIdentifier)

Obtains an inflight bean for the given identifier. An "In Flight" bean is one that is currently being created but has not finished construction and been registered as a singleton just yet. For example in the case whereby a bean as a PostConstruct method that also triggers bean resolution of the same bean.

Type Parameters:

T - The bean type

Parameters:

beanIdentifier - The bean identifier

Returns:

The bean

getCurrentQualifier

@Nullable
Qualifier<?> getCurrentQualifier()

Returns:

The current bean identifier

setCurrentQualifier

void setCurrentQualifier(@Nullable
                         Qualifier<?> qualifier)

Sets the current qualifier.

Parameters:

qualifier - The qualifier
