public interface Property
Interface for a property of an event of type BeanEventType (JavaBean event). Properties are designed to handle the different types of properties for such events: indexed, mapped, simple, nested, or a combination of those.

  • Method Details

    • getPropertyType

      EPTypeClass getPropertyType(BeanEventType eventType, BeanEventTypeFactory beanEventTypeFactory)
      Returns the property type.
      Parameters:
      eventType - is the event type representing the JavaBean

      Returns:
      property type class

    • getGetter

      EventPropertyGetterSPI getGetter(BeanEventType eventType, EventBeanTypedEventFactory eventBeanTypedEventFactory, BeanEventTypeFactory beanEventTypeFactory)
      Returns value getter for the property of an event of the given event type.
      Parameters:
      eventType - is the type of event to make a getter for
      eventBeanTypedEventFactory - factory for event beans and event types
      beanEventTypeFactory - bean factory
