Interface EntityEditor.EditorValue.Propagator<T>

Type Parameters:

T - the source attribute value type

Enclosing interface:

EntityEditor.EditorValue<T>

public static interface EntityEditor.EditorValue.Propagator<T>

Propagates derived attribute values when a source attribute value changes.

A EntityEditor.EditorValue.Propagator provides a unified mechanism for updating associated attribute values, replacing the need to separately handle value propagation in the editor (via EntityEditor.EditorValue.edited() listeners) and in entities (via overriding).

The EntityEditor.EditorValue.Propagator.Setter provided to propagate(Object, Setter) routes to the appropriate target depending on context:

• When editing via the editor (Value.set(Object)), values are set via the respective EntityEditor.EditorValue instances, triggering edit events.
• When setting values in an entity (EntityEditor.EditorValue.set(Entity, Object)), values are set directly on the entity via Entity.set(Attribute, Object).
