      • getSuperType

        public ItemType getSuperType​(TypeHierarchy th)
        Description copied from interface: ItemType
        Get the type from which this item type is derived by restriction. This is the supertype in the XPath type heirarchy, as distinct from the Schema base type: this means that the supertype of xs:boolean is xdt:anyAtomicType, whose supertype is item() (rather than xs:anySimpleType).

        In fact the concept of "supertype" is not really well-defined, because the types form a lattice rather than a hierarchy. The only real requirement on this function is that it returns a type that strictly subsumes this type, ideally as narrowly as possible.

        Specified by:
        getSuperType in interface ItemType
        Returns:
        the supertype, or null if this type is item()

        getDisplayName in interface SchemaType
        Returns:
        a lexical QName identifying the type
