Interface SchemaType

    • Method Detail

      • getName

        java.lang.String getName()
        Get the local name of this type
        Returns:
        the local name of this type definition, if it has one. Return null in the case of an anonymous type.
      • getTargetNamespace

        java.lang.String getTargetNamespace()
        Get the target namespace of this type
        Returns:
        the target namespace of this type definition, if it has one. Return null in the case of an anonymous type, and in the case of a global type defined in a no-namespace schema.
      • getFingerprint

        int getFingerprint()
        Get the fingerprint of the name of this type
        Returns:
        the fingerprint. Returns an invented fingerprint for an anonymous type.
      • getDisplayName

        java.lang.String getDisplayName()
        Get the display name of the type: that is, a lexical QName with an arbitrary prefix
        Returns:
        a lexical QName identifying the type. In the case of an anonymous type, an internally-generated name is returned
      • getStructuredQName

        StructuredQName getStructuredQName()
        Get the name of the type as a StructuredQName
        Returns:
        a StructuredQName identifying the type. In the case of an anonymous type, an internally-generated name is returned
      • getEQName

        java.lang.String getEQName()
        Get the name of this type as an EQName, that is, a string in the format Q{uri}local.
        Returns:
        an EQName identifying the type. In the case of an anonymous type, an internally-generated name is returned
      • isComplexType

        boolean isComplexType()
        Test whether this SchemaType is a complex type
        Returns:
        true if this SchemaType is a complex type
      • isSimpleType

        boolean isSimpleType()
        Test whether this SchemaType is a simple type
        Returns:
        true if this SchemaType is a simple type
      • isAtomicType

        boolean isAtomicType()
        Test whether this SchemaType is an atomic type
        Returns:
        true if this SchemaType is an atomic type

        Returns:
        true if this SchemaType is an anonymous type
      • getBlock

        int getBlock()
        Returns the value of the 'block' attribute for this type, as a bit-significant integer with fields such as Derivation.DERIVATION_LIST and Derivation.DERIVATION_EXTENSION. This corresponds to the property "prohibited substitutions" in the schema component model.
        Returns:
        the value of the 'block' attribute for this type
      • getBaseType

        SchemaType getBaseType()
        Returns the base type that this type inherits from. This method can be used to get the base type of a type that is known to be valid. If this type is a Simpletype that is a built in primitive type then null is returned.
        Returns:
        the base type, or null if this is xs:anyType (the root of the type hierarchy)
      • getDerivationMethod

        int getDerivationMethod()
        Gets the integer code of the derivation method used to derive this type from its parent. Returns zero for primitive types.
        Returns:
        a numeric code representing the derivation method, for example Derivation.DERIVATION_RESTRICTION
      • getFinalProhibitions

        int getFinalProhibitions()
        Get the types of derivation that are not permitted, by virtue of the "final" property.
        Returns:
        the types of derivation that are not permitted, as a bit-significant integer containing bits such as Derivation.DERIVATION_EXTENSION
      • allowsDerivation

        boolean allowsDerivation​(int derivation)
        Determines whether derivation (of a particular kind) from this type is allowed, based on the "final" property
        Parameters:
        derivation - the kind of derivation, for example Derivation.DERIVATION_LIST
        Returns:
        true if this kind of derivation is allowed
      • analyzeContentExpression

        void analyzeContentExpression​(Expression expression,
                                      int kind)
                               throws XPathException
        Analyze an XPath expression to see whether the expression is capable of delivering a value of this type. This method is called during static analysis of a query or stylesheet to give compile-time warnings when "impossible" paths are used.
        Parameters:
        expression - the expression that delivers the content
        kind - the node kind whose content is being delivered: Type.ELEMENT, Type.ATTRIBUTE, or Type.DOCUMENT
        Throws:
        XPathException - if the expression will never deliver a value of the correct type
      • atomize

        AtomicSequence atomize​(NodeInfo node)
                        throws XPathException
        Get the typed value of a node that is annotated with this schema type.
        Parameters:
        node - the node whose typed value is required
        Returns:
        the typed value.
        Throws:
        XPathException - if the node cannot be atomized, for example if this is a complex type with element-only content
        Since:
        8.5. Changed in 9.5 to return the new type AtomicSequence
      • isSameType

        boolean isSameType​(SchemaType other)
        Test whether this is the same type as another type. They are considered to be the same type if they are derived from the same type definition in the original XML representation (which can happen when there are multiple includes of the same file)
        Parameters:
        other - the other type
        Returns:
        true if this is the same type as other
      • getDescription

        java.lang.String getDescription()
        Get a description of this type for use in error messages. This is the same as the display name in the case of named types; for anonymous types it identifies the type by its position in a source schema document.
        Returns:
        text identifing the type, for use in a phrase such as "the type XXXX".
      • checkTypeDerivationIsOK

        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.
        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
      • getSystemId

        java.lang.String getSystemId()
        Get the URI of the schema document where the type was originally defined.
        Returns:
        the URI of the schema document. Returns null if the information is unknown or if this is a built-in type
      • isIdType

        boolean isIdType()
                  throws MissingComponentException
        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
        Returns:
        true if this type is an ID type
        Throws:
        MissingComponentException
      • isIdRefType

        boolean isIdRefType()
                     throws MissingComponentException
        Ask whether this type is an IDREF or IDREFS type. This is defined to be any simple type who typed value may contain atomic values of type xs:IDREF: that is, it includes types derived from IDREF or IDREFS by restriction, list, or union
        Returns:
        true if this type is an IDREF type
        Throws:
        MissingComponentException
