Method Details

attributes

ObservableValueSet<Attribute<?>> attributes()

Indicates which editor attributes are modified.

Only attributes with an associated EntityEditor.EditorValue are reported, that is, attributes which have been accessed via EntityEditor.value(Attribute), typically by binding them to a component. The columns underlying a modified foreign key are therefore absent, as is any attribute the editor never touched.

Note that modified attributes are included, regardless of whether the entity exists, and that this set may be empty while ObservableState.is() is true, since the modified state also reflects additional() states.

Returns:

an ObservableValueSet indicating the currently modified attributes

additional

ValueSet<ObservableState> additional()

Controls the 'additional' modified states for this EntityEditor.Modified instance, which are combined with the entity modified state using OR.

Returns:

the ValueSet controlling the additional modified states
