This Java library provides a factory to create generic java.lang.reflect.Type variations, such as Map<Number, Point>.
All currently required feature are implemented. This project is in maintenance mode.
// Map<Number, Point>
final Type type = GenericTypes.generic(Map.class, Number.class, Point.class);
// List<Number>
final Type type = GenericTypes.generic(List.class, Number.class);Super- and subtypes such as List<? super Point> or List<? extends Number> can be created in the following way:
// List<? super Point>
final Type type = GenericTypes.generic(List.class, GenericTypes.supertype(Point.class));
// List<? extends Number>
final Type type = GenericTypes.generic(List.class, GenericTypes.subtype(Number.class));Use static imports to shorten the above calls to:
// List<? super Point>
final Type type = generic(List.class, supertype(Point.class));
// List<? extends Number>
final Type type = generic(List.class, subtype(Number.class));and then go crazy with this:
// List<Map<? extends Number, ? super Point>>
final Type type = generic(List.class, generic(Map.class, subtype(Number.class), supertype(Point.class)));To use this project just declare the following dependency inside your POM:
