Examples of org.directwebremoting.io.InputStreamFactory

org.directwebremoting.io.InputStreamFactory
This class gives some lifecycle to an InputStream. 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 #getInputStream()} 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. {@link SimpleInputStreamFactory}. @see SimpleInputStreamFactory @author Lance Semmens [uklance at gmail dot com]
