Field Type Annotations

These annotations control how individual fields are rendered and what input widget is used in edit mode.

---

@Stereotype

Target: FIELD

Sets the input widget type for a field. Mateu infers a default stereotype from the Java type (e.g. String → text input, boolean → checkbox), but @Stereotype overrides that inference.

@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Stereotype {
    FieldStereotype value();
}

Attributes
