javax.enterprise.inject.spi.CDI<T>

org.jboss.weld.AbstractCDI<T>

Type Parameters:

T -

All Implemented Interfaces:

Iterable<T>, Instance<T>, Provider<T>

Direct Known Subclasses:

SimpleCDI

public abstract class AbstractCDI<T>
extends CDI<T>

Abstract implementation of CDI which forwards all Instance methods to a delegate. Furthermore, it allows the calling class to be identified using the getCallingClassName() method.

Methods

Modifier and Type	Method and Description
void	destroy(T instance) When called, the container destroys the instance if the active context object for the scope type of the bean supports destroying bean instances.
T	get() Provides a fully-constructed and injected instance of T.
protected String	getCallingClassName() Examines StackTraceElements to figure out which class invoked a method on CDI.
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<T>	iterator()
Instance<T>	select(Annotation... qualifiers) Obtains a child Instance for the given additional required qualifiers.
<U extends T> Instance<U>	select(Class<U> subtype, Annotation... qualifiers) Obtains a child Instance for the given required type and additional required qualifiers.
<U extends T> Instance<U>	select(TypeLiteral<U> subtype, Annotation... qualifiers) Obtains a child Instance for the given required type and additional required qualifiers.

public T get()

Description copied from interface: Provider

Provides a fully-constructed and injected instance of T.

select

public Instance<T> 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 extends T> 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 extends T> 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.

destroy

public void destroy(T instance)

Description copied from interface: Instance

When called, the container destroys the instance if the active context object for the scope type of the bean supports destroying bean instances. All normal scoped 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

getCallingClassName

protected String getCallingClassName()

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