MethodInjectionPoint

protected MethodInjectionPoint(EnhancedAnnotatedCallable<T,X,java.lang.reflect.Method> callable,
                               Bean<?> declaringBean,
                               java.lang.Class<?> declaringComponentClass,
                               boolean observerOrDisposer,
                               InjectionPointFactory factory,
                               BeanManagerImpl manager)

Method Detail

invoke

public abstract T invoke(java.lang.Object receiver,
                         java.lang.Object specialValue,
                         BeanManagerImpl manager,
                         CreationalContext<?> ctx,
                         java.lang.Class<? extends java.lang.RuntimeException> exceptionTypeToThrow)

Invokes the method.

Parameters:

receiver - the instance to receive the method invocation or null if this is a static method

specialValue - value to be passed to the special parameter (observer or disposer parameter) or null if the method is not an observer or disposer

manager - the bean manager

ctx - the creational context

exceptionTypeToThrow - exception type to be used to wrap potential exceptions within

Returns:

the value returned from the method

getAnnotated

public abstract AnnotatedMethod<X> 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

getType

public java.lang.reflect.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 java.util.Set<java.lang.annotation.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 java.lang.annotation.Annotation> A getQualifier(java.lang.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 java.lang.reflect.Member>

getMember

public java.lang.reflect.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 java.util.List<ParameterInjectionPoint<?,X>> getParameterInjectionPoints()

getInjectionPoints

public java.util.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.
