public class PartialResponseWriter
extends ResponseWriterWrapper
```
PartialResponseWriter decorates an existing ResponseWriter to support the generation of a partial response suitable for Ajax operations. In addition to the markup generation methods inherited from javax.faces.context.ResponseWriter, this class provides methods for constructing the standard partial response elements.
