All Implemented Interfaces:

javax.ws.rs.ext.MessageBodyReader<java.lang.Object>, javax.ws.rs.ext.MessageBodyWriter<java.lang.Object>

Direct Known Subclasses:

XmlCollectionJaxbProvider

public abstract class AbstractCollectionJaxbProvider
extends AbstractJaxbProvider<java.lang.Object>

An abstract provider for T[], Collection<T>, and its subtypes as long as they have the public default constructor or are interfaces implemented by one the following classes:

• ArrayList
• LinkedList
• HashSet
• TreeSet
• Stack

T must be a JAXB type annotated with XmlRootElement.

Implementing classes may extend this class to provide specific marshalling and unmarshalling behaviour.

When unmarshalling a UnmarshalException will result in a WebApplicationException being thrown with a status of 400 (Client error), and a JAXBException will result in a WebApplicationException being thrown with a status of 500 (Internal Server error).

When marshalling a JAXBException will result in a WebApplicationException being thrown with a status of 500 (Internal Server error).
