/**
*
* 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 (
* XML Schema Part2: Datatypes
* specification ) and hence may be difficult to write.
*
*
* 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:
*
*
* // 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;
* }
*
*
*
* There is a static parse and print method corresponding to each parse and
* print method respectively in the {@link DatatypeConverterInterface
* DatatypeConverterInterface}.
*
* The static methods defined in the class can also be used to specify
* a parse or a print method in a javaType binding declaration.
*
*
* 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.
*
*
*
* 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.
