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 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 DatatypeConverter.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.

JAXB Providers are required to call this method at some point before allowing any of the JAXB client marshal or unmarshal operations to occur. This is necessary to configure the datatype converter that should be used to perform the print and parse conversions.

Calling this api repeatedly will have no effect - the DatatypeConverterInterface instance passed into the first invocation is the one that will be used from then on.
Parameters:
  converter - an instance of a class that implements the DatatypeConverterInterface class - this parameter must not be null.
throws:
  IllegalArgumentException - if the parameter is null
