Class DataObservationSupport

java.lang.Object

io.jmix.core.observation.DataObservationSupport

@Component("core_DataObservationSupport")
public class DataObservationSupport
extends Object

Support class for observing data operations such as entity loading, counting, value loading, and entity saving.

This class uses an ObservationRegistry if observation functionality is enabled in the application configuration.

Observation functionality can be turned on or off using the jmix.core.data-observation-enabled property in the application's configuration.
