The basetype of this type with given class symbol.
The basetype of this type with given class symbol.
Returns NoType
if this type does not have base
in any of its base
types.
Is this type exactly Nothing (no vars, aliases, refinements etc allowed)?
Is this type exactly Nothing (no vars, aliases, refinements etc allowed)?
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.
This is the same as matches
except that it also matches => T
with T
and vice versa.

The normalized prefix of this type is:
The normalized prefix of this type is:
- For a type alias, the normalized prefix of its alias.
- For all other named type and class infos: the prefix.
- Inherited by all other type proxies.
None
for all other types.
