## Interface DatatypeConverterInterface

-     public interface DatatypeConverterInterface

  The DatatypeConverterInterface is for JAXB provider use only. A JAXB provider must supply a class that implements this interface. JAXB Providers are required to call the `DatatypeConverter.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. Calling this api repeatedly will have no effect - the DatatypeConverter instance passed into the first invocation is the one that will be used from then on.

  This interface defines the parse and print methods. There is one parse and print method for each XML schema datatype specified in the the default binding Table 5-1 in the JAXB specification.

  The parse and print methods defined here are invoked by the static parse and print methods defined in the `DatatypeConverter` class.

  A parse method for a XML schema datatype must be capable of converting any lexical representation of the XML schema datatype ( specified by the XML Schema Part2: Datatypes specification into a value in the value space of 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.

  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.

  The prefix xsd: is used to refer to XML schema datatypes XML Schema Part2: Datatypes specification.
