31 * <p>
32 * The javaType binding declaration can be used to customize the binding of
33 * an XML schema datatype to a Java datatype. Customizations can involve
34 * writing a parse and print method for parsing and printing lexical
35 * representations of a XML schema datatype respectively. However, writing
36 * parse and print methods requires knowledge of the lexical representations (
37 * <a href="http://www.w3.org/TR/xmlschema-2/"> XML Schema Part2: Datatypes
38 * specification </a>) and hence may be difficult to write.
39 * </p>
40 * <p>
41 * This class makes it easier to write parse and print methods. It defines
42 * static parse and print methods that provide access to a JAXB provider's
43 * implementation of parse and print methods. These methods are invoked by
44 * custom parse and print methods. For example, the binding of xsd:dateTime
45 * to a long can be customized using parse and print methods as follows:
46 * <blockquote>
47 * <pre>
48 * // Customized parse method
49 * public long myParseCal( String dateTimeString ) {
50 * java.util.Calendar cal = DatatypeConverter.parseDateTime(dateTimeString);
51 * long longval = convert_calendar_to_long(cal); //application specific
52 * return longval;
53 * }
54 *
55 * // Customized print method
56 * public String myPrintCal( Long longval ) {
57 * java.util.Calendar cal = convert_long_to_calendar(longval) ; //application specific
58 * String dateTimeString = DatatypeConverter.printDateTime(cal);
59 * return dateTimeString;
60 * }
61 * </pre>
62 * </blockquote>
63 * <p>
64 * There is a static parse and print method corresponding to each parse and
65 * print method respectively in the {@link DatatypeConverterInterface
66 * DatatypeConverterInterface}.
67 * <p>
68 * The static methods defined in the class can also be used to specify
69 * a parse or a print method in a javaType binding declaration.
70 * </p>
71 * <p>
72 * JAXB Providers are required to call the
73 * {@link #setDatatypeConverter(DatatypeConverterInterface)
74 * setDatatypeConverter} api at some point before the first marshal or unmarshal
75 * operation (perhaps during the call to JAXBContext.newInstance). This step is
76 * necessary to configure the converter that should be used to perform the
77 * print and parse functionality.
78 * </p>
79 *
80 * <p>
81 * A print method for a XML schema datatype can output any lexical
82 * representation that is valid with respect to the XML schema datatype.
83 * If an error is encountered during conversion, then an IllegalArgumentException,
84 * or a subclass of IllegalArgumentException must be thrown by the method.
85 * </p>
