# Interface EventListenerProvider

All Known Implementing Classes:
  `EventListenerParameters`

public interface EventListenerProvider

Definition of an interface that is evaluated by a `ConfigurationBuilder` to initialize event listeners.

This interface allows a convenient initialization of a configuration builder with event listeners to be registered at the managed configuration object. The `configure()` method of `BasicConfigurationBuilder` checks whether a parameters object passed to it implements this interface. If this is the case, all event listeners defined by the object are added to the internal list managed by the builder. They are then automatically registered at the managed configuration when it is created. When using a corresponding implementation the configuration of event listeners can be done in the same fluent API style as the other initialization of the configuration builder.
