Method Detail

getDecoratorMethods

public static java.util.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(AnnotatedType<?> type,
                                                                           java.lang.Iterable<InjectionPoint> injectionPoints)

getOuterDelegate

public static <T> T getOuterDelegate(Bean<T> bean,
                                     T instance,
                                     CreationalContext<T> creationalContext,
                                     java.lang.Class<T> proxyClass,
                                     InjectionPoint originalInjectionPoint,
                                     BeanManagerImpl manager,
                                     java.util.List<Decorator<?>> decorators)

checkDelegateType

public static void checkDelegateType(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(java.util.Set<java.lang.reflect.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(Decorator<?> decorator)

Indicates whether a Decorator is passivation capable or not.

Returns:
