Class ConstructorInjectionPoint<T>

java.lang.Object

org.jboss.weld.injection.ConstructorInjectionPoint<T>

Type Parameters:

T -

All Implemented Interfaces:

InjectionPoint, WeldInjectionPointAttributes<T,Constructor<T>>

Direct Known Subclasses:

ProxyClassConstructorInjectionPointWrapper

public class ConstructorInjectionPoint<T>
extends Object

High-level representation of an injected constructor. This class does not need to be serializable because it is never injected.

Constructor Detail

ConstructorInjectionPoint

protected ConstructorInjectionPoint(EnhancedAnnotatedConstructor<T> constructor,
                         Bean<T> declaringBean,
                         Class<?> declaringComponentClass,
                         InjectionPointFactory factory,
                         BeanManagerImpl manager)

Method Detail

newInstance

public T newInstance(BeanManagerImpl manager,
            CreationalContext<?> ctx)

newInstance

protected T newInstance(Object[] parameterValues)

getParameterValues

public Object[] getParameterValues(BeanManagerImpl manager,
                          CreationalContext<?> ctx,
                          CreationalContext<?> invocationContext)

Helper method for getting the current parameter values from a list of annotated parameters.

Parameters:

parameters - The list of annotated parameter to look up

manager - The Bean manager

Returns:

The object array of looked up values

getAnnotated

public AnnotatedConstructor<T> getAnnotated()

Description copied from interface: InjectionPoint

Obtain an instance of AnnotatedField or AnnotatedParameter, depending upon whether the injection point is an injected field or a constructor/method parameter.

Specified by:

getAnnotated in interface InjectionPoint

Returns:

an AnnotatedField or AnnotatedParameter

getSignature

public ConstructorSignature getSignature()

getComponentConstructor

public AnnotatedConstructor<T> getComponentConstructor()

hashCode

public int hashCode()

equals

public boolean equals(Object obj)

getType

public Type getType()

Description copied from interface: InjectionPoint

Get the required type of injection point.

Specified by:

getType in interface InjectionPoint

Returns:

the required type

getQualifiers

public Set<Annotation> getQualifiers()

Description copied from interface: InjectionPoint

Get the required qualifiers of the injection point.

Specified by:

getQualifiers in interface InjectionPoint

Returns:

the required qualifiers

getBean

public Bean<?> getBean()

Description copied from interface: InjectionPoint

Get the Bean object representing the bean that defines the injection point. If the injection point does not belong to a bean, return a null value.

Specified by:

getBean in interface InjectionPoint

Returns:

the Bean object representing bean that defines the injection point, of null if the injection point does not belong to a bean

isDelegate

public boolean isDelegate()

Description copied from interface: InjectionPoint

Determines if the injection point is a decorator delegate injection point.

Specified by:

isDelegate in interface InjectionPoint

Returns:

true if the injection point is a decorator delegate injection point, and false otherwise

isTransient

public boolean isTransient()

Description copied from interface: InjectionPoint

Determines if the injection is a transient field.

Specified by:

isTransient in interface InjectionPoint

Returns:

true if the injection point is a transient field, and false otherwise

getQualifier

public <A extends Annotation> A getQualifier(Class<A> annotationType)

Description copied from interface: WeldInjectionPointAttributes

Returns an instance of a given qualifier annotation or null if a given qualifier is not present on the injection point.

Specified by:

getQualifier in interface WeldInjectionPointAttributes<T,S extends Member>

getMember

public Member getMember()

Description copied from interface: InjectionPoint

Get the Field object in the case of field injection, the Method object in the case of method parameter injection or the Constructor object in the case of constructor parameter injection.

Specified by:

getMember in interface InjectionPoint

Returns:

the member

getParameterInjectionPoints

public List<ParameterInjectionPoint<?,X>> getParameterInjectionPoints()

getInjectionPoints

public Set<InjectionPoint> getInjectionPoints()

Returns a set of InjectionPoint instances of this constructor/method. This set never contains a SpecialParameterInjectionPoint and is therefore suitable for use outside of Weld. The returned set is immutable.

toString

public String toString()

Overrides:

toString in class Object
