Method Detail

invoke

public abstract T invoke(Object receiver,
                         Object specialValue,
                         BeanManagerImpl manager,
                         javax.enterprise.context.spi.CreationalContext<?> ctx,
                         Class<? extends 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 javax.enterprise.inject.spi.AnnotatedMethod<X> getAnnotated()

Specified by:

getAnnotated in interface javax.enterprise.inject.spi.InjectionPoint

getType

public Type getType()

Specified by:

getType in interface javax.enterprise.inject.spi.InjectionPoint

getQualifiers

public Set<Annotation> getQualifiers()

Specified by:

getQualifiers in interface javax.enterprise.inject.spi.InjectionPoint

getBean

public javax.enterprise.inject.spi.Bean<?> getBean()

Specified by:

getBean in interface javax.enterprise.inject.spi.InjectionPoint

isDelegate

public boolean isDelegate()

Specified by:

isDelegate in interface javax.enterprise.inject.spi.InjectionPoint

isTransient

public boolean isTransient()

Specified by:

isTransient in interface javax.enterprise.inject.spi.InjectionPoint

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()

Specified by:

getMember in interface javax.enterprise.inject.spi.InjectionPoint

getParameterInjectionPoints

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

getInjectionPoints

public Set<javax.enterprise.inject.spi.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.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
