.
The following example creates a feature type for a capital, as a special kind of city,
named "Utopia" by default:
FeatureTypeBuilder builder; // Create a feature type for a city, which contains a name and a population. builder = new FeatureTypeBuilder() .setName("City"); builder.addAttribute(String.class) .setName("name").setDefaultValue("Utopia"); builder.addAttribute(Integer.class).setName("population"); FeatureType city = builder.build(); // Create a subclass for a city which is also a capital. builder = new FeatureTypeBuilder().setName("Capital").setSuperTypes(city); builder.addAttribute(String.class).setName("parliament"); FeatureType capital = builder.build();A call to
System.out.println(capital)
prints the following table:
Capital ⇾ City ┌────────────┬─────────┬─────────────┬───────────────┐ │ Name │ Type │ Cardinality │ Default value │ ├────────────┼─────────┼─────────────┼───────────────┤ │ name │ String │ [1 … 1] │ Utopia │ │ population │ Integer │ [1 … 1] │ │ │ parliament │ String │ [1 … 1] │ │ └────────────┴─────────┴─────────────┴───────────────┘
