Methods

Modifier and Type	Method and Description
protected BeanManagerImpl	ambiguousBeanManager(String callerClassName, Set<BeanManagerImpl> managers) Callback that allows to override the behavior when class that invoked CDI.current() is placed in multiple bean archives.
void	cleanup()
void	destroy(Object instance) On Instance.destroy(Object) being called, the container destroys the instance if the active context object for the scope type of the bean supports destroying bean instances.
Object	get() Provides a fully-constructed and injected instance of T.
BeanManagerProxy	getBeanManager() Get the CDI BeanManager for the current context
protected String	getCallingClassName() Examines StackTraceElements to figure out which class invoked a method on CDI.
protected Instance<Object>	getInstance()
boolean	isAmbiguous() Determines if there is more than one bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent Instance was injected.
boolean	isUnsatisfied() Determines if there is no bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent Instance was injected.
Iterator<Object>	iterator()
Instance<Object>	select(Annotation... qualifiers) Obtains a child Instance for the given additional required qualifiers.
<U> Instance<U>	select(Class<U> subtype, Annotation... qualifiers) Obtains a child Instance for the given required type and additional required qualifiers.
<U> Instance<U>	select(TypeLiteral<U> subtype, Annotation... qualifiers) Obtains a child Instance for the given required type and additional required qualifiers.
String	toString()
protected BeanManagerImpl	unsatisfiedBeanManager(String callerClassName) Callback that allows to override the behavior when CDI.current() is not called from within a bean archive.

getBeanManager

public BeanManagerProxy getBeanManager()

Description copied from class: CDI

Get the CDI BeanManager for the current context

Specified by:

getBeanManager in class CDI<Object>

Returns:

getCallingClassName

protected String getCallingClassName()

Examines StackTraceElements to figure out which class invoked a method on CDI.

iterator

public Iterator<Object> iterator()

get

public Object get()

Description copied from interface: Provider

Provides a fully-constructed and injected instance of T.

select

public Instance<Object> select(Annotation... qualifiers)

Description copied from interface: Instance

Obtains a child Instance for the given additional required qualifiers.

Parameters:

qualifiers - the additional required qualifiers

Returns:

the child Instance

select

public <U> Instance<U> select(Class<U> subtype,
                     Annotation... qualifiers)

Description copied from interface: Instance

Obtains a child Instance for the given required type and additional required qualifiers.

Type Parameters:

U - the required type

Parameters:

subtype - a Class representing the required type

qualifiers - the additional required qualifiers

Returns:

the child Instance

select

public <U> Instance<U> select(TypeLiteral<U> subtype,
                     Annotation... qualifiers)

Description copied from interface: Instance

Obtains a child Instance for the given required type and additional required qualifiers.

Type Parameters:

U - the required type

Parameters:

subtype - a TypeLiteral representing the required type

qualifiers - the additional required qualifiers

Returns:

the child Instance

isUnsatisfied

public boolean isUnsatisfied()

Description copied from interface: Instance

Determines if there is no bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent Instance was injected.

Returns:

true if there is no bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent Instance was injected, or false otherwise.

isAmbiguous

public boolean isAmbiguous()

Description copied from interface: Instance

Determines if there is more than one bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent Instance was injected.

Returns:

true if there is more than one bean that matches the required type and qualifiers and is eligible for injection into the class into which the parent Instance was injected, or false otherwise.

getInstance

protected Instance<Object> getInstance()

toString

public String toString()

Overrides:

toString in class Object

cleanup

public void cleanup()

destroy

public void destroy(Object instance)

Description copied from interface: Instance

On Instance.destroy(Object) being called, the container destroys the instance if the active context object for the scope type of the bean supports destroying bean instances. All built in contexts support destroying bean instances.

The instance passed should either be a dependent scoped bean instance, or the client proxy for a normal scoped bean instance.

Parameters:

instance - the instance to destroy
