final def matches(that: Type)(using Context): Boolean

Is this type close enough to that type so that members with the two types would override each other?

Is this type close enough to that type so that members with the two types would override each other?

This means:

  • Either both types are polytypes with the same number of type parameters and their result types match after renaming corresponding type parameters
  • Or both types are method types with =:=-equivalent(*) parameter types and matching result types after renaming corresponding parameter types if the method types are dependent.
  • Or both types are =:=-equivalent
  • Or neither type takes term or type parameters.

(*) when matching with a Java method, we also regard Any and Object as equivalent parameter types. (TODO)

This function will always use unsafe-nulls semamtics to check the types. This is because we are using a relaxed rule (ignoring Null types) to check overriding Java methods.

  • For all other named type and class infos: the prefix.
  • Inherited by all other type proxies.
  • None for all other types.

final def typeParams(using Context): List[TypeConstructorParam]

The type parameters of this type, if it is a type constructor.

The type parameters of this type, if it is a type constructor.

If this type is a type constructor, returns a non-empty list of its type parameters.

For all other types (proper types, any-kinded types, methodic types and package refs), returns Nil.

Special case: for Nothing, returns Nil as well (although Nothing is universally-kinded, so it is a type constructor for all possible type constructor signatures).
