Public Instance methods

update(update={})

Receives updates from FSMonitor#add_path

@param [Hash] opts The options to update the observer @option opts [:symbol] :command The command to instruct the 

  observer to execute.
  * +:add_path+ Indicates the +:data+ field contains a path.
  * +:stop_capture+ indicates that capturing has ceased. The
      observer will change ownership of the files, and switch
      to the user specified at #initialize.

@option opts [String] :data Contains a resource path when the 

  * +:add_path+ Command is called, otherwise ignored.
