      • getConversionRules

        public ConversionRules getConversionRules()
        Get the conversion rules implemented by this type. The conversion rules reflect variations between different versions of the W3C specifications, for example XSD 1.1 allows "+INF" as a lexical representation of xs:double, while XSD 1.0 does not.
        Specified by:
        getConversionRules in class ItemType
        Returns:
        the conversion rules
      • matches

        public boolean matches​(XdmItem item)
        Determine whether this item type matches a given item.
        Specified by:
        matches in class ItemType
        Parameters:
        item - the item to be tested against this item type
        Returns:

      • subsumes

        public boolean subsumes​(ItemType other)
