Class FileWatcher

java.lang.Object

ghidra.framework.main.logviewer.ui.FileWatcher

public class FileWatcher
extends Object

The FileWatcher *watches* a single file and fires a change notification whenever the file is modified. A couple notes: 1. To keep from processing change events every time the file is modified, which may be too frequent and cause processing issues, we use a simple polling mechanism. 2. Changes in the file are identified by inspecting the File.lastModified() timestamp. 3. The WatchService mechanism is not being used here since we cannot specify a polling rate.
