+ // do dynamic installation and upgrading of the current Flash plugin in
+ // use (dojox.flash.Install). If you want to call methods on the Flash object
+ // embedded into the page it is your responsibility to use Flash's ExternalInterface
+ // API and get a reference to the Flash object yourself.
+ //
+ // To use dojox.flash, you must first wait until Flash is finished loading
+ // and initializing before you attempt communication or interaction.
+ // To know when Flash is finished use dojo.connect:
+ //
+ // dojo.connect(dojox.flash, "loaded", myInstance, "myCallback");
+ //
+ // Then, while the page is still loading provide the file name:
+ //
+ // dojox.flash.setSwf(dojo.moduleUrl("dojox", "_storage/storage.swf"));
+ //
+ // If no SWF files are specified, then Flash is not initialized.
+ //
+ // Your Flash must use Flash's ExternalInterface to expose Flash methods and
+ // to call JavaScript.
+ //
+ // setSwf can take an optional 'visible' attribute to control whether
+ // the Flash object is visible or not on the page; the default is visible:
+ //
+ // dojox.flash.setSwf(dojo.moduleUrl("dojox", "_storage/storage.swf"),
+ // false);
+ //
+ // Once finished, you can query Flash version information:
+ //
+ // dojox.flash.info.version
+ //
+ // Or can communicate with Flash methods that were exposed:
+ //
+ // var f = dojox.flash.get();
+ // var results = f.sayHello("Some Message");
+ //
+ // Your Flash files should use DojoExternalInterface.as to register methods;
+ // this file wraps Flash's normal ExternalInterface but correct various
+ // serialization bugs that ExternalInterface has.
+ //
+ // Note that dojox.flash is not meant to be a generic Flash embedding
+ // mechanism; it is as generic as necessary to make Dojo Storage's
+ // Flash Storage Provider as clean and modular as possible. If you want
+ // a generic Flash embed mechanism see SWFObject
+ // (http://blog.deconcept.com/swfobject/).
+ //
+ // Notes:
+ // Note that dojox.flash can currently only work with one Flash object
+ // on the page; it does not yet support multiple Flash objects on
+ // the same page.
+ //
+ // Your code can detect whether the Flash player is installing or having
+ // its version revved in two ways. First, if dojox.flash detects that
+ // Flash installation needs to occur, it sets dojox.flash.info.installing
+ // to true. Second, you can detect if installation is necessary with the
+ // following callback:
+ //
+ // dojo.connect(dojox.flash, "installing", myInstance, "myCallback");
+ //
+ // You can use this callback to delay further actions that might need Flash;
+ // when installation is finished the full page will be refreshed and the
+ // user will be placed back on your page with Flash installed.
+ //
+ // -------------------
+ // Todo/Known Issues
+ // -------------------
+ // * On Internet Explorer, after doing a basic install, the page is
+ // not refreshed or does not detect that Flash is now available. The way
+ // to fix this is to create a custom small Flash file that is pointed to
+ // during installation; when it is finished loading, it does a callback
+ // that says that Flash installation is complete on IE, and we can proceed
+ // to initialize the dojox.flash subsystem.
+ // * Things aren't super tested for sending complex objects to Flash
+ // methods, since Dojo Storage only needs strings

+// summary:
+// A class that records actions taken by a user when they are offline,
+// suitable for replaying when the network reappears.
+// description:
+// The basic idea behind this method is to record user actions that would
+// normally have to contact a server into an action log when we are
+// offline, so that later when we are online we can simply replay this log
+// in the order user actions happened so that they can be executed against
+// the server, causing synchronization to happen.
+//
+// When we replay, for each of the actions that were added, we call a
+// method named onReplay that applications should connect to and
+// which will be called over and over for each of our actions --
+// applications should take the offline action
+// information and use it to talk to a server to have this action
+// actually happen online, 'syncing' themselves with the server.
+//
+// For example, if the action was "update" with the item that was updated, we
+// might call some RESTian server API that exists for updating an item in
+// our application. The server could either then do sophisticated merging
+// and conflict resolution on the server side, for example, allowing you
+// to pop up a custom merge UI, or could do automatic merging or nothing
+// of the sort. When you are finished with this particular action, your
+// application is then required to call continueReplay() on the actionLog object
+// passed to onReplay() to continue replaying the action log, or haltReplay()
+// with the reason for halting to completely stop the syncing/replaying
+// process.
+//
+// For example, imagine that we have a web application that allows us to add
+// contacts. If we are offline, and we update a contact, we would add an action;
+// imagine that the user has to click an Update button after changing the values
+// for a given contact:
+//
+// dojox.off.whenOffline(dojo.byId("updateButton"), "onclick", function(evt){
+// // get the updated customer values
+// var customer = getCustomerValues();
+//
+// // we are offline -- just record this action
+// var action = {name: "update", customer: customer};
+// dojox.off.sync.actions.add(action)
+//
+// // persist this customer data into local storage as well
+// dojox.storage.put(customer.name, customer);
+// })
+//
+// Then, when we go back online, the dojox.off.sync.actions.onReplay event
+// will fire over and over, once for each action that was recorded while offline:
+//
+// dojo.connect(dojox.off.sync.actions, "onReplay", function(action, actionLog){
+// // called once for each action we added while offline, in the order
+// // they were added
+// if(action.name == "update"){
+// var customer = action.customer;
+//
+// // call some network service to update this customer
+// dojo.xhrPost({
+// url: "updateCustomer.php",
+// content: {customer: dojo.toJson(customer)},
+// error: function(err){
+// actionLog.haltReplay(err);
+// },
+// load: function(data){
+// actionLog.continueReplay();
+// }
+// })
+// }
+// })
+//
+// Note that the actions log is always automatically persisted locally while using it, so
+// that if the user closes the browser or it crashes the actions will safely be stored
+// for later replaying.

+ // Example usage:

+ // dojox.off.sync.log.add({actionName: "create", itemType: "document",
+ // {title: "Message", content: "Hello World"}});
+ //
+ // The object literal is simply a custom object appropriate

+ // of a user action that will be executed when we go back online
+ // and replay this log. In the above example,
+ // "create" is the name of this action; "documents" is the
