Method Detail

getDecoratorMethods

public static Set<InvokableAnnotatedMethod<?>> getDecoratorMethods(BeanManagerImpl beanManager,
                                                                   WeldDecorator<?> decorator)

Determines the set of InvokableAnnotatedMethods representing decorated methods of the specified decorator. A decorated method is any method declared by a decorated type which is implemented by the decorator.

Parameters:

beanManager - the bean manager

decorator - the specified decorator

Returns:

the set of InvokableAnnotatedMethods representing decorated methods of the specified decorator

findDelegateInjectionPoint

public static WeldInjectionPointAttributes<?,?> findDelegateInjectionPoint(javax.enterprise.inject.spi.AnnotatedType<?> type,
                                                                           Iterable<javax.enterprise.inject.spi.InjectionPoint> injectionPoints)

getOuterDelegate

public static <T> T getOuterDelegate(javax.enterprise.inject.spi.Bean<T> bean,
                                     T instance,
                                     javax.enterprise.context.spi.CreationalContext<T> creationalContext,
                                     Class<T> proxyClass,
                                     javax.enterprise.inject.spi.InjectionPoint originalInjectionPoint,
                                     BeanManagerImpl manager,
                                     List<javax.enterprise.inject.spi.Decorator<?>> decorators)

checkDelegateType

public static void checkDelegateType(javax.enterprise.inject.spi.Decorator<?> decorator)

Check whether the delegate type implements or extends all decorated types.

Parameters:

decorator -

Throws:

DefinitionException - If the delegate type doesn't implement or extend all decorated types

checkAbstractMethods

public static <T> void checkAbstractMethods(Set<Type> decoratedTypes,
                                            EnhancedAnnotatedType<T> type,
                                            BeanManagerImpl beanManager)

Check all abstract methods are declared by the decorated types.

Parameters:

type -

beanManager -

delegateType -

Throws:

DefinitionException - If any of the abstract methods is not declared by the decorated types

isPassivationCapable

public static boolean isPassivationCapable(javax.enterprise.inject.spi.Decorator<?> decorator)

Indicates whether a Decorator is passivation capable or not.

Returns:
