Examples of org.directwebremoting.io.OutputStreamLoader

org.directwebremoting.io.OutputStreamLoader
This class gives some lifecycle to an OutputStream. There may be times (particularly with downloading files to browsers) when it is not clear if the data will ever be read. A call to {@link #load(OutputStream)} is a signal that we really to want datanow and that if any processing is needed, if should be done. A call to {@link #close()} is a signal that whether or not getInputStream wascalled, the data is no longer required. @author Joe Walker [joe at getahead dot ltd dot uk]
