Annotation Type ExtensionHolder

@Retention(RUNTIME)
@Target(FIELD)
public @interface ExtensionHolder

An annotation to indicate that a field is intended to hold “extensions”. Such a field will store any unknown property that is associated with the object the field belongs to.

This is how the LinkML-Java runtime supports LinkML’s extra_slots.allowed: True feature.

Only a field typed as a Map<String, Object> should be annotated with this annotation.
