30 * The DatatypeConverterInterface is for JAXB provider use only. A
31 * JAXB provider must supply a class that implements this interface.
32 * JAXB Providers are required to call the
33 * {@link DatatypeConverter#setDatatypeConverter(DatatypeConverterInterface)
34 * DatatypeConverter.setDatatypeConverter} api at
35 * some point before the first marshal or unmarshal operation (perhaps during
36 * the call to JAXBContext.newInstance). This step is necessary to configure
37 * the converter that should be used to perform the print and parse
38 * functionality. Calling this api repeatedly will have no effect - the
39 * DatatypeConverter instance passed into the first invocation is the one that
40 * will be used from then on.
41 * </p>
42 *
43 * <p>
44 * This interface defines the parse and print methods. There is one
45 * parse and print method for each XML schema datatype specified in the
46 * the default binding Table 5-1 in the JAXB specification.
47 * </p>
48 *
49 * <p>
50 * The parse and print methods defined here are invoked by the static parse
51 * and print methods defined in the {@link DatatypeConverter DatatypeConverter}
52 * class.
53 * </p>
54 *
55 * <p>
56 * A parse method for a XML schema datatype must be capable of converting any
57 * lexical representation of the XML schema datatype ( specified by the
58 * <a href="http://www.w3.org/TR/xmlschema-2/"> XML Schema Part2: Datatypes
59 * specification</a> into a value in the value space of the XML schema datatype.
60 * If an error is encountered during conversion, then an IllegalArgumentException
61 * or a subclass of IllegalArgumentException must be thrown by the method.
62 *
63 * </p>
64 *
65 * <p>
66 * A print method for a XML schema datatype can output any lexical
67 * representation that is valid with respect to the XML schema datatype.
68 * If an error is encountered during conversion, then an IllegalArgumentException,
69 * or a subclass of IllegalArgumentException must be thrown by the method.
