public class FileResource

extends StreamResource

Managed File based Resource. This is convenient when you want to dynamically set and get the information from the resource. For instance, the Resource does not need to be actively monitored if all access to the resource goes through this type of Resource. It can notify the change as soon as the Writer or OutputStream has been closed.
