Foswiki::Contrib::MailerContrib::WebNotify 
  internal package Foswiki::Contrib::MailerContrib::WebNotify 
Object that represents the contents of a 
WebNotify topic in a Foswiki web.
Note that 
$Foswiki::Plugins::SESSION is used to find the Foswiki session, and
must be set up before this class is used.
  new($web, $topic) 
 
-  
$web - web name
  -  
$topic - topic name
  -  
$noexpandgroups - True will prevent expansion of group subscriptions     (False is best for checking subscriptions, but True is best for     writing results back to $topic)
 
 
Create a new object by parsing the content of the given topic in the
given web. This is the normal way to load a 
WebNotify topic. If the
topic does not exist, it will create an empty object.
  writeWebNotify() 
Write the object to the 
WebNotify topic it was read from.
If there is a problem writing the topic (e.g. it is locked),
the method will throw an exception.
  getSubscriber($name, $noAdd) 
 
-  
$name - Name of subscriber (wikiname with no web or email address)
  -  
$noAdd - If false or undef, a new subscriber will be created for this name
 
 
Get a subscriber from the list of subscribers, and return a reference
to the Subscriber object. If $noAdd is true, and the subscriber is not
found, undef will be returned. Otherwise a new Subscriber object will
be added if necessary.
  getSubscribers() 
Get a list of all subscriber names (unsorted)
  subscribe($name, $topics, $depth, $options) 
 
-  
$name - Name of subscriber (wikiname with no web or email address)
  -  
$topics - wildcard expression giving topics to subscribe to
  -  
$depth - Child depth to scan (default 0)
  -  
$options - Bitmap of Mailer::Const options
 
 
Add a subscription, adding the subscriber if necessary.
  unsubscribe($name, $topics, $depth) 
 
-  
$name - Name of subscriber (wikiname with no web or email address)
  -  
$topics - wildcard expression giving topics to subscribe to
  -  
$depth - Child depth to scan (default 0)
 
 
Add an unsubscription, adding the subscriber if necessary. An unsubscription
is a specific request to ignore notifications for a topic for this
particular subscriber.
  stringify() -> string 
Return a string representation of this object, in 
WebNotify format.
Optional 
$subscribersOnly parameter to only print the parsed subscription list.
Used when running a mailnotify, where printing out the entire 
WebNotify topic is confusing,
as it's different from the actual topic contents, but doesn't inform the user why.
  processChange($change, $db, $changeSet, $seenSet, $allSet) 
  
Find all subscribers that are interested in the given change. Only the most
recent change to each topic listed in the .changes file is retained. This
method does 
not change this object.
  processCompulsory($topic, $db, \%allSet) 
  
  isEmpty() -> boolean 
Return true if there are no subscribers
