Class BlueprintSpringInterfaceHelper

java.lang.Object

com.predic8.membrane.annot.parser.BlueprintSpringInterfaceHelper

public class BlueprintSpringInterfaceHelper
extends Object

Helper class for simulating the Spring context startup order:

1. Call constructor
2. Set properties (possibly child beans, themselves fully initialized)
3. call ApplicationContextAware.setApplicationContext(org.springframework.context.ApplicationContext), if the bean implements ApplicationContextAware
4. call Lifecycle.start(), if the bean implements Lifecycle.

To avoid calling ApplicationContextAware.setApplicationContext(org.springframework.context.ApplicationContext) on a bean A before all other properties have been set on it (step 2), an instance B of this class is created. "B.client = A" and "A depends on B" are the relationships modeled using Blueprint. This causes "B.setClient(A)" to be executed

• after all other properties have been set on A
• before A is returned by BlueprintContainer.getComponentInstance(String) or used as a child bean

which fulfills our requirements.
