| /** |
| * <p> |
| * The javaType binding declaration can be used to customize the binding of |
| * an XML schema datatype to a Java datatype. Customizations can involve |
| * writing a parse and print method for parsing and printing lexical |
| * representations of a XML schema datatype respectively. However, writing |
| * parse and print methods requires knowledge of the lexical representations ( |
| * <a href="http://www.w3.org/TR/xmlschema-2/"> XML Schema Part2: Datatypes |
| * specification </a>) and hence may be difficult to write. |
| * </p> |
| * <p> |
| * This class makes it easier to write parse and print methods. It defines |
| * static parse and print methods that provide access to a JAXB provider's |
| * implementation of parse and print methods. These methods are invoked by |
| * custom parse and print methods. For example, the binding of xsd:dateTime |
| * to a long can be customized using parse and print methods as follows: |
| * <blockquote> |
| * <pre> |
| * // Customized parse method |
| * public long myParseCal( String dateTimeString ) { |
| * java.util.Calendar cal = DatatypeConverter.parseDateTime(dateTimeString); |
| * long longval = convert_calendar_to_long(cal); //application specific |
| * return longval; |
| * } |
| * |
| * // Customized print method |
| * public String myPrintCal( Long longval ) { |
| * java.util.Calendar cal = convert_long_to_calendar(longval) ; //application specific |
| * String dateTimeString = DatatypeConverter.printDateTime(cal); |
| * return dateTimeString; |
| * } |
| * </pre> |
| * </blockquote> |
| * <p> |
| * There is a static parse and print method corresponding to each parse and |
| * print method respectively in the {@link DatatypeConverterInterface |
| * DatatypeConverterInterface}. |
| * <p> |
| * The static methods defined in the class can also be used to specify |
| * a parse or a print method in a javaType binding declaration. |
| * </p> |
| * <p> |
| * JAXB Providers are required to call the |
| * {@link #setDatatypeConverter(DatatypeConverterInterface) |
| * setDatatypeConverter} api at some point before the first marshal or unmarshal |
| * operation (perhaps during the call to JAXBContext.newInstance). This step is |
| * necessary to configure the converter that should be used to perform the |
| * print and parse functionality. |
| * </p> |
| * |
| * <p> |
| * A print method for a XML schema datatype can output any lexical |
| * representation that is valid with respect to the XML schema datatype. |
| * If an error is encountered during conversion, then an IllegalArgumentException, |
| * or a subclass of IllegalArgumentException must be thrown by the method. |
| * </p> |
