EventMachine::FileWatch

Should be redefined with the user’s custom callback that will be fired when the file is deleted. When the file is deleted, stop_watching will be called after this to make sure everything is cleaned up correctly.

Note that on linux (with inotify), file_deleted will not be called until all open file descriptors to the file have been closed.

    # File lib/em/file_watch.rb, line 39
39:     def file_deleted
40:     end

Should be redefined with the user’s custom callback that will be fired when the file is modified.

    # File lib/em/file_watch.rb, line 30
30:     def file_modified
31:     end

Should be redefined with the user’s custom callback that will be fired when the file is moved or renamed.

    # File lib/em/file_watch.rb, line 43
43:     def file_moved
44:     end

Returns the path that EventMachine::watch_file was originally called with. The current implementation does not pick up on the new filename after a rename occurs.

    # File lib/em/file_watch.rb, line 25
25:     def path
26:       @path
27:     end

Discontinue monitoring of the file. This involves cleaning up the underlying monitoring details with kqueue/inotify, and in turn firing unbind. This will be called automatically when a file is deleted. User code may call it as well.

    # File lib/em/file_watch.rb, line 49
49:     def stop_watching
50:       EventMachine::unwatch_filename(@signature)
51:     end
