    • Method Detail

      • addBean

        <T> SyntheticBeanBuilder<T> addBean​(java.lang.Class<T> implementationClass)
        Creates a SyntheticBeanBuilder that allows configuring a new synthetic bean of given implementationClass. The synthetic bean will be registered at the end of the @Synthesis method.
        Type Parameters:
        T - the implementation class of the new synthetic bean
        Parameters:
        implementationClass - the implementation class of the new synthetic bean, must not be null
        Returns:
        a new SyntheticBeanBuilder, never null

      • addObserver

        <T> SyntheticObserverBuilder<T> addObserver​(java.lang.Class<T> eventType)
        Creates a SyntheticObserverBuilder that allows configuring a new synthetic observer for given eventType. The synthetic observer will be registered at the end of the @Synthesis method.
        Type Parameters:
        T - the observed event type of the new synthetic observer
        Parameters:
        eventType - the observed event type of the new synthetic observer, must not be null
        Returns:
        a new SyntheticObserverBuilder, never null

      • addObserver

        <T> SyntheticObserverBuilder<T> addObserver​(Type eventType)
        Creates a SyntheticObserverBuilder that allows configuring a new synthetic observer for given eventType. The synthetic observer will be registered at the end of the @Synthesis method.

        This method is supposed to be called with explicitly provided type arguments. For example, to define a synthetic observer of event type List<String>, one would call: 

        
 // types is of type Types
 // syntheticComponents is of type SyntheticComponents
 syntheticComponents.<List<String>>addObserver(types.parameterized(List.class, String.class))
     ...
        Type Parameters:
        T - the observed event type of the new synthetic observer
        Parameters:
        eventType - the observed event type of the new synthetic observer, must not be null
        Returns:
        a new SyntheticObserverBuilder, never null
