An object that supports editing zero or more properties of a bean. By implementing IsEditor , the Widgets need only implement the single asEditor method, which isolates the Widgets from any API changes that may occur in the component Editor logic.

HasEditorErrors indicates that the Editor wishes to receive any unconsumed errors reported by sub-Editors through EditorDelegate.
