LockFileEventImpl

public class FileEventImpl
extends AbstractEvent
implements FileEvent

An event for files, that is, an event is produced and sent as soon as a file (or a directory) is created or stored in a specific folder.
This event source terminates as soon as an event has been handled. However, since it polls, one has to ensure that a handled file is deleted or moved to another folder. Otherwise the source will create another event for the file.
