        Ask whether this type is an ID type. This is defined to be any simple type who typed value may contain atomic values of type xs:ID: that is, it includes types derived from ID by restriction, list, or union. Note that for a node to be treated as an ID in XSD 1.0, its typed value must be a *single* atomic value of type ID; the type of the node, however, can still allow a list. But in XSD 1.1, a list of IDs is permitted
        Specified by:
        isIdType in interface SchemaType
        Overrides:

        Specified by:
        isIdRefType in interface SchemaType

      • getRedefinitionLevel

        public int getRedefinitionLevel()
        Get the redefinition level. This is zero for a component that has not been redefined; for a redefinition of a level-0 component, it is 1; for a redefinition of a level-N component, it is N+1. This concept is used to support the notion of "pervasive" redefinition: if a component is redefined at several levels, the top level wins, but it is an error to have two versions of the component at the same redefinition level.
        Specified by:
        getRedefinitionLevel in interface SchemaComponent
        Returns:
        the redefinition level

      • toExportString

        public java.lang.String toExportString()
        Return a string representation of this ItemType suitable for use in stylesheet export files. This differs from the result of toString() in that it will not contain any references to anonymous types. Note that it may also use the Saxon extended syntax for union types and tuple types. The default implementation returns the result of calling toString().
        Specified by:
        toExportString in interface ItemType

        public java.lang.String toString()
        Description copied from class: LocalUnionType
        Produce a string representation of the type name. If the type is anonymous, an internally-allocated type name will be returned.
        Specified by:
        toString in interface ItemType
        Overrides:
        toString in class LocalUnionType
        Returns:

      • checkTypeDerivationIsOK

        public void checkTypeDerivationIsOK​(SchemaType base,
                                    int block)
                             throws SchemaException
        Check that this type is validly derived from a given type, following the rules for the Schema Component Constraint "Is Type Derivation OK (Simple)" (3.14.6) or "Is Type Derivation OK (Complex)" (3.4.6) as appropriate.
        Specified by:
        checkTypeDerivationIsOK in interface SchemaType
        Parameters:
        base - the base type; the algorithm tests whether derivation from this type is permitted
        block - the derivations that are blocked by the relevant element declaration
        Throws:
        SchemaException - if the derivation is not allowed

      • getComponentAsFunction

        public Function getComponentAsFunction()
        Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".
        Specified by:
        getComponentAsFunction in interface SchemaComponent
        Returns:
        the schema component represented as a function from property names to property values.
