def seqLitType(tree: SeqLiteral, elemType: Type)(using Context): Type

Inherited methods

def accessibleType(tpe: Type, superAccess: Boolean)(using Context): Type

If tpe is a named type, return the type with those alternatives as denotations which are accessible (or NoType, if no alternatives are accessible).

If tpe is a named type, return the type with those alternatives as denotations which are accessible (or NoType, if no alternatives are accessible).

Also performs the following normalizations on the type tpe. (1) if the owner of the denotation is a package object, it is assured that the package object shows up as the prefix. (2) in Java compilation units, Object is replaced by defn.FromJavaObjectType
