Interface XSDatatype

    • Method Detail

      • getName

        java.lang.String getName()
        gets the local name of the type. If this type is an anonymous type, then this method returns null.

        In the terminology of the spec, this method returns the name property of this simple type component. If the name property is absent, this method returns null.

      • getNamespaceUri

        java.lang.String getNamespaceUri()
        Gets the namespace URI of this simple type definition.
      • displayName

        java.lang.String displayName()
        gets the displayable name of this type. This method always return something. It is useful to provide a message to the user.

        This method is an ad-hoc method and there is no corresponding property in the spec.

      • convertToLexicalValue

        java.lang.String convertToLexicalValue​(java.lang.Object valueObject,
                                               SerializationContext context)
                                        throws java.lang.IllegalArgumentException
        converts value object back to the corresponding value in the lexical space.

        This method does the reverse operation of the createValue method. The returned string is not necessarily the canonical representation. Also note that the implementation may accept invalid values without throwing IllegalArgumentException. To make sure that the result is actually a valid representation, call the isValid method.

        Be careful not to confuse this method with The serializeJavaObject method, which is defined in the DatabindableDatatype method.

        Parameters:
        context - Context information that will be possibly used for the conversion. Currently, this object is used only by QName, but may be extended in the future.
        Throws:
        java.lang.IllegalArgumentException - if the type of the given object is not the expected one. For example, this exception is thrown if you pass a BigInteger object to the "gYear" type.
      • getVariety

        int getVariety()
        gets the variety of this simple type.
        Returns:
        VARIETY_ATOMIC, VARIETY_LIST, or VARIETY_UNION.
      • isFinal

        boolean isFinal​(int derivationType)
        checks if this type is declared as final for the specified kind of derivation.

        In the terminology of the spec, this method can be used to examine the final property of this component.

        Parameters:
        derivationType - one of pre-defined values (DERIVATION_BY_XXX).
      • isFacetApplicable

        int isFacetApplicable​(java.lang.String facetName)
        returns if the specified facet is applicable to this datatype.
        Returns:
        APPLICABLE
        if the facet is applicable
        FIXED
        if the facet is already fixed (that is,not applicable)
        NOT_ALLOWED
        if the facet is not applicable to this datatype at all. this value is also returned for unknown facets.
      • getApplicableFacetNames

        java.lang.String[] getApplicableFacetNames()
        Gets the names of all applicable facets.
      • getFacetObject

        DataTypeWithFacet getFacetObject​(java.lang.String facetName)
        gets the facet object that restricts the specified facet. This method can be used to access various details of how facets are applied to this datatype.
        Returns:
        null if no such facet object exists.
      • getBaseType

        XSDatatype getBaseType()
        gets the base type of this type. This method returns null if this object represents the simple ur-type.

        This method is intended to capture the semantics of the base type definition property of the simple type component, but there is an important difference.

        Specifically, if you derive a type D from another type B, then calling D.getBaseType() does not necessarily return B. Instead, it may return an intermediate object (that represents a facet). Calling the getBaseType method recursively will eventually return B.

      • getAncestorBuiltinType

        XSDatatype getAncestorBuiltinType()
        Gets the nearest ancestor built-in type.

        This method traverses the inheritance chain from this datatype to the root type (anySimpleType) and return the first built-in type it finds.

        For example, if you derive a type Foo from NCName and Bar from Foo, then this method returns NCName.

        Returns:
        Always return non-null valid object.
      • isDerivedTypeOf

        boolean isDerivedTypeOf​(XSDatatype baseType,
                                boolean restrictionAllowed)
        tests if this type is a derived type of the specified type.

        This method is an implementation of "Type Derivation OK (Simple)" of the spec. Therefore use caution if what you want is a casual method because this method may cause a lot of unintuitive result.

        Note to implementors Use the static version of this method defined in the XSDatatypeImpl class. You don't need to implement this method from scratch.

        Parameters:
        restrictionAllowed - This test needs "a subset of {extension,restriction,list,union} (of which only restriction is actually relevant). If this flag is set to true, this method behaves as if the empty set is passed as the set. This is usually what you want if you're simply trying to check the derivation relationship.

        If this flag is set to false, this method behaves as if {restriction} is passed as the set.

      • isAlwaysValid

        boolean isAlwaysValid()
        Returns true if this datatype is known to accept any string. This is just a hint that allows the client code to do certain optimization.

        This method can return false even if the datatype actually accepts any string. That is, it's perfectly OK for any datatype to return false from this method.
