Class enthought.​traits.​ustr_trait.​HasUniqueStrings

Mixin or base class for objects containing lists with items containing string valued traits that must be unique.

List traits within the class that contain items which have string traits which must be unique should indicate this by attaching metadata of the form:

unique_string = 'trait1, trait2, ..., traitn'

where each 'traiti' value is the name of a trait within each list item that must contain unique string data.

For example:

usa = List( State, unique_string = 'name, abbreviation' )
