public class EntityAttributesFilter
extends AbstractMetadataFilter

A filter that adds EntityAttributes extension content to entities in order to drive software behavior based on them.

The entities to annotate are identified with a Predicate, and multiple attributes can be associated with each.

As of 3.4.0, another predicate can be set to validate pre-existing extension content to better protect use cases of this component.
