      public UnionType(String nsUri, String newTypeName, XSDatatype[] memberTypes) throws org.relaxng.datatype.DatatypeException
      derives a new datatype from atomic datatypes by union
      Throws:
      org.relaxng.datatype.DatatypeException
  • Method Details

    • getBaseType

      public final XSDatatype getBaseType()
      Description copied from interface: XSDatatype
      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.

    • displayName

      public final String displayName()
      Description copied from interface: XSDatatype
      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.

    • isContextDependent

      public boolean isContextDependent()
      The union type is context-dependent if one of the member types is so.
      Specified by:
      isContextDependent in interface org.relaxng.datatype.Datatype
      Overrides:
      isContextDependent in class XSDatatypeImpl
    • getVariety

      public final int getVariety()
      Variety of the UnionType is VARIETY_UNION. So this method always returns VARIETY_UNION.
      Returns:
      VARIETY_ATOMIC, VARIETY_LIST, or VARIETY_UNION.
    • isFacetApplicable

      public final int isFacetApplicable(String facetName)
      Description copied from interface: XSDatatype
      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.
    • checkFormat

      protected final boolean checkFormat(String content, org.relaxng.datatype.ValidationContext context)
      Specified by:
      checkFormat in class XSDatatypeImpl
    • _createValue

      public Object _createValue(String content, org.relaxng.datatype.ValidationContext context)
      Description copied from class: XSDatatypeImpl
      converts a whitespace-processed lexical value into the corresponding value object
      Specified by:
      _createValue in class XSDatatypeImpl
    • getJavaObjectType

      public Class getJavaObjectType()
      Description copied from interface: DatabindableDatatype
      gets the type of the objects that are created by the createJavaObject method.
    • convertToLexicalValue

      public String convertToLexicalValue(Object o, SerializationContext context)
      Description copied from interface: XSDatatype
      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.
    • _checkValid

      protected void _checkValid(String content, org.relaxng.datatype.ValidationContext context) throws org.relaxng.datatype.DatatypeException
      Description copied from class: XSDatatypeImpl
      actual 'meat' of the checkValid method
      Overrides:
      _checkValid in class ConcreteType
      Throws:
      org.relaxng.datatype.DatatypeException
