public booleanfeed_PublishTemplatizedAction(com.facebook.api.TemplatizedAction action)
Publishes a templatized action for the current user. The action will appear in their minifeed, and may appear in their friends' newsfeeds depending upon a number of different factors. When a template match exists between multiple distinct users (like "Bob recommends Bizou" and "Sally recommends Bizou"), the feed entries may be combined in the newfeed (to something like "Bob and sally recommend Bizou"). This happens automatically, and *only* if the template match between the two feed entries is identical.

Feed entries are not aggregated for a single user (so "Bob recommends Bizou" and "Bob recommends Le Charm" *will not* become "Bob recommends Bizou and Le Charm").

If the user's action involves one or more of their friends, list them in the 'targetIds' parameter. For example, if you have "Bob says hi to Sally and Susie", and Sally's UID is 1, and Susie's UID is 2, then pass a 'targetIds' paramters of "1,2". If you pass this parameter, you can use the "{target}" token in your templates. Probably it also makes it more likely that Sally and Susie will see the feed entry in their newsfeed, relative to any other friends Bob might have. It may be a good idea to always send a list of all the user's friends, and avoid using the "{target}" token, to maximize distribution of the story through the newsfeed.

The only strictly required parameter is 'titleTemplate', which must contain the "{actor}" token somewhere inside of it. All other parameters, options, and tokens are optional, and my be set to null if being omitted.

Not that stories will only be aggregated if *all* templates match and *all* template parameters match, so if two entries have the same templateTitle and titleData, but a different bodyTemplate, they will not aggregate. Probably it's better to use bodyGeneral instead of bodyTemplate, for the extra flexibility it provides.

public java.lang.StringgetRawResponse()
Returns a string representation for the last API response recieved from Facebook, exactly as sent by the API server. Note that calling this method consumes the data held in the internal buffer, and thus it may only be called once per API call.

return

The response format in which results to FacebookMethod calls are returned

return
the format: either XML, JSON, or null (API default)

      return "xml";
public java.lang.ObjectgetResponsePOJO()
Returns a JAXB object of the type that corresponds to the last API call made on the client. Each Facebook Platform API call that returns a Document object has a JAXB response object associated with it. The naming convention is generally intuitive. For example, if you invoke the 'user_getInfo' API call, the associated JAXB response object is 'UsersGetInfoResponse'.

An example of how to use this method:

FacebookRestClient client = new FacebookRestClient("apiKey", "secretKey", "sessionId");
client.friends_get();
FriendsGetResponse response = (FriendsGetResponse)client.getResponsePOJO();
List friends = response.getUid();

This is particularly useful in the case of API calls that return a Document object, as working with the JAXB response object is generally much simple than trying to walk/parse the DOM by hand.

This method can be safely called multiple times, though note that it will only return the response-object corresponding to the most recent Facebook Platform API call made.

Note that you must cast the return value of this method to the correct type in order to do anything useful with it.

return
a JAXB POJO ("Plain Old Java Object") of the type that corresponds to the last API call made on the client. Note that you must cast this object to its proper type before you will be able to do anything useful with it.
