Class Coordinator

java.lang.Object
  com.sun.xml.bind.v2.runtime.Coordinator

All Implemented Interfaces:

ValidationEventHandler, ErrorHandler

Direct Known Subclasses:

UnmarshallingContext, XMLSerializer

public abstract class Coordinator
extends Object
implements ErrorHandler, ValidationEventHandler

Object that coordinates the marshalling/unmarshalling.

This class takes care of the logic that allows code to obtain UnmarshallingContext and XMLSerializer instances during the unmarshalling/marshalling.

This is done by using a ThreadLocal. Therefore one unmarshalling/marshalling episode has to be done from the beginning till end by the same thread. (Note that the same Coordinator can be then used by a different thread for an entirely different episode.) This class also maintains the user-configured instances of XmlAdapters.

This class implements ErrorHandler and propages erros to this object as the ValidationEventHandler, which will be implemented in a derived class.
