Following the same pattern as our earlier examples, this function requires the location code and a callback function that is used to deliver the RSSWeather object that is created from the feed contentThis object is created on line 5, and its variables are populated as the corresponding events are received from the RssTask The RssTask itself is created on line 15 and a reference to it is held in a script variable This is necessary, because we subscribe to the feed by setting its interval variable to request that the feed be polled for updates every 60 seconds, until such time as its stop() function is called If the user changes the location in the user interface, this function will be called again, and we need to remove the previous subscriptionWe do this by calling the stop() function on lines 11 to 13 As you saw in our discussion of the feed itself, we need to extract some of the information that we need from the <item> element and the rest from three foreign elementsWe therefore assign functions to the onItem and onForeignEvent variables so that we are notified when these elements are received Notice that, unlike our previous examples, we don t use an HttpRequest to fetch the data and a PullParser to process it all of this is taken care of by the RssTask object Like HttpRequest, RssTask is (indirectly) derived from javafxasyncTask, so it does most of its work in the background and runs its callback functions in the main thread The code in the onItem function is straightforward It receives an argument of type Item that contains the result of parsing the content of the <item> element of the feed and extracts values from the title and description variablesThe code that handles the description value, on lines 19 to 30 of Listing 27-10, is nontrivial because it needs to extract the URL of the weather image from the embedded HTML <img> tag The code in the onForeignEvent function is different from that in onItem because it receives events from the XML parser that the RssTask uses to process the feed data, instead of JavaFX objects created from the parser output Because the values that we are interested in are carried in attributes of the <wind>, <condition>, and <forecast> elements, we intercept the START_ELEMENT event for each of the elements and use its getAttributeValue() function to get the required values, and then store them in the corresponding variables of the RSSWeather object Finally, when the feed data has been processed, the RssTask object calls the onDone function, which in turn delivers the RSSWeather object to the callback passed to getRSSWeather() functionThis whole process will be repeated automatically every 60 seconds because we set the interval variable of the RssTask object and subscribed to the.

The mutex and event are both associated with the message block or other data structure The mutex defines the critical code section for accessing the data structure object The event is used to signal the fact that there is a new message Generalizing, the mutex ensures the object's invariants (or safety properties), and the event signals that the object has changed state (eg, a message has been added or removed from a message buffer), possibly being put into a known state (eg, there is at least one message in the message buffer) One thread (the producer in Program 8-2) locks the data structure, changes the object's state by creating a new message, and sets or pulses the event associated with the fact that there is a new message At least one other thread (the consumer in this example) waits on the event for the object to reach the desired state The wait must occur outside the critical section so that the producer can access the object A consumer thread can also lock the mutex, test the object's state (eg, is there a new message in the buffer ), and avoid the event wait if the object is already in the desired state

The Atom feed protocol is newer and more complex than RSS, but for the JavaFX developer, it is just as easy to write an application that works with an Atom feed as it is to handle an RSS feedYou connect to an Atom feed by using the javafxdatafeedatomAtomTask class, which, like RssTask, derives from FeedTask Whereas an RSS feed consists of one or more <item> elements nested inside a <channel> element, in Atom the feed itself is represented by a <feed> element, which is converted to a Feed object, and the individual items in the feed are contained in <entry> elements, which become Entry objectsThe AtomTask class has two callback variables, listed in Table 27-9, that are used to deliver Feed and Entry objects to application code

Function to which the feed s Feed object is delivered Function to which Entry objects that hold the feed s content are delivered Class used to convert the XML content of the feed to the corresponding JavaFX objects
