GenericApplicationListener (Spring Framework 5.2.12.RELEASE API)

All Superinterfaces:
ApplicationListener<ApplicationEvent>, EventListener, Ordered
All Known Implementing Classes:
ApplicationListenerMethodAdapter, GenericApplicationListenerAdapter, SourceFilteringListener
```
public interface GenericApplicationListener
extends ApplicationListener<ApplicationEvent>, Ordered
```
Extended variant of the standard ApplicationListener interface, exposing further metadata such as the supported event and source type.
As of Spring Framework 4.2, this interface supersedes the Class-based SmartApplicationListener with full handling of generic event types.
Since:
4.2

- Method Detail
  - supportsEventType
```
boolean supportsEventType(ResolvableType 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
