Package org.openhab.core.model.yaml

Interface YamlModelListener<T extends YamlElement>

@NonNullByDefault public interface YamlModelListener<T extends YamlElement>
The YamlModelListener interface is responsible for managing a particular model type with data processed from YAML configuration files.

Implementors are notified whenever a YAML model changed that contains elements of the given type. They MUST declare at least YamlModelListener as service to automatically register them with the repository.
