Constructor Detail

InterceptorBeanBuilder

protected InterceptorBeanBuilder(WebBeansContext webBeansContext,
                                 javax.enterprise.inject.spi.AnnotatedType<T> annotatedType,

Method Detail

isInterceptorEnabled

public abstract boolean isInterceptorEnabled()

If this method returns false the getBean() method must not get called.

Returns:

true if the Interceptor is enabled and a Bean should get created

checkInterceptorConditions

protected void checkInterceptorConditions()

defineInterceptorMethods

public boolean defineInterceptorMethods()

Grab all methods which act as interceptors for the various InterceptionTypes.

This method will also check some rules, e.g. that there must not be more than a single AroundInvoke method on a class.

For the interceptors where multiple are allowed, the following rules apply:

• Superclass methods first
• Non-private methods override and derogates their superclass counterparts.
• Private methods with the same signature stack (superclass first).
• There must only be a single method for each InterceptorType in the same class.

Returns:

true if we found some interceptor methods

createBean

protected abstract B createBean(Class<T> beanClass,
                                boolean enabled,
                                Map<javax.enterprise.inject.spi.InterceptionType,Method[]> interceptionMethods)

getBean

public B getBean()
