hasDoneChanges

public boolean hasDoneChanges()

Description copied from interface: IFeature

Is queried by the framework after a feature has been executed to find out if this feature should appear in the undo stack of e.g. an editor. By default all features should appear there (see implementation in AbstractFeature), but features may decide to override this behavior. Note that this is a dynamic attribute of the feature that is queried each time after the feature has been executed.

IMPORTANT NOTE: The implementor of the feature is responsible for correctly implementing this method! It might lead to inconsistencies in the command stack if this method returns false although the feature did changes.

Specified by:

hasDoneChanges in interface IFeature

Overrides:

hasDoneChanges in class AbstractFeature

Returns:

true if the feature should appear in the undo stack, false otherwise
