SmartApplicationListener (Spring Framework 5.2.12.RELEASE API)

All Superinterfaces:
ApplicationListener<ApplicationEvent>, EventListener, Ordered
All Known Implementing Classes:
DefaultSimpUserRegistry, GenericApplicationListenerAdapter, MultiServerUserRegistry, SourceFilteringListener
```
public interface SmartApplicationListener
extends ApplicationListener<ApplicationEvent>, Ordered
```
Extended variant of the standard ApplicationListener interface, exposing further metadata such as the supported event and source type.
For full introspection of generic event types, consider implementing the GenericApplicationListener interface instead.

- Method Detail
  - supportsEventType
```
boolean supportsEventType(Class<? extends ApplicationEvent> eventType)
```
    Determine whether this listener actually supports the given event type.
    Parameters:
    eventType - the event type (never null)
  - supportsSourceType
```
default boolean supportsSourceType(@Nullable
                                   Class<?> sourceType)
```
    Determine whether this listener actually supports the given source type.
    The default implementation always returns true.
    Parameters:
    sourceType - the source type, or null if no source
  - getOrder
```
default int getOrder()
```
    Determine this listener's order in a set of listeners for the same event.
    The default implementation returns Ordered.LOWEST_PRECEDENCE.
    Specified by:
    getOrder in interface Ordered
    Returns:
    the order value
