Examples of MessageBodyWriter

javax.ws.rs.ext.MessageBodyWriter
Contract for a provider that supports the conversion of a Java type to a stream. To add a MessageBodyWriter implementation, annotate the implementation class with @Provider.
A MessageBodyWriter implementation may be annotated with {@link javax.ws.rs.Produces} to restrict the media types for which it willbe considered suitable. @param T the type that can be written @see Provider @see javax.ws.rs.Produces
org.restlet.ext.jaxrs.internal.wrappers.provider.MessageBodyWriter
Interface to access a wrapped an initialized {@link javax.ws.rs.ext.MessageBodyWriter} @author Stephan Koops @see javax.ws.rs.ext.MessageBodyWriter
