Class ReifiedType

java.lang.Object
space.arim.dazzleconf.reflect.ReifiedType
Direct Known Subclasses:
ReifiedType.Annotated
public class ReifiedType extends Object
A possibly generic type, with its arguments fully specified.

This type is a runtime stand-in for fully reified generic information. Given that Java discards generic type data at runtime, this type exists to retain that data. Lastly, while this class itself contains the raw generic data, it is designed for low-level usage. See TypeToken for an ergonomic high-level version.

This class should be considered sealed and not subclassed. Equality is defined for any two reified types based on whether the raw type and arguments match, or annotations if ReifiedType.Annotated is used.

This class and its subtype ReifiedType.Annotated are both immutable.
