Class JAXBSerialiser

java.lang.Object

com.peterphi.std.util.jaxb.JAXBSerialiser

public class JAXBSerialiser
extends Object

A thread-safe, caching JAXB helper type. This wraps a JAXBContext and its Marshallers and Unmarshallers, allowing their concurrent use
This helper also translates the exceptions that can be thrown during a JAXB serialise/deserialise operation in a JAXBRuntimeException
