For the first variation, AlwaysLocalScope will have a dynamic assignment: function AlwaysLocalScope() { info("AlwaysLocalScope{scopedVariable}", typeof(scopedVariable)); eval("scopedVariable = 'AlwaysLocalScope'"); info("AlwaysLocalScope{scopedVariable}", "scopedVariable=" + scopedVariable + " type=" + typeof(scopedVariable)); var scopedVariable; } The modified code is shown in bold, and the assignment of scopedVariable is executed Using eval in this manner has no effect, and the dynamic execution of the code is the same as if the code had not been modified The advantage with eval is that you can assign a piece of code to a text buffer, and then execute that buffer The scope of scopedVariable has not been changed because the var keyword still exists in the function declaration The declaration when parsed by the JavaScript processor will result in a local variable declaration.

For example, you might define plain Java classes like NewsStory or RestaurantInfo and define methods to create these objects from byte arrays So long as the class structure remains exactly the same, you can reuse the data across different app versions However, odds are high that the record format will need to change at some point to support later application features In order to future-proof your record storage, you should always tag the beginning of an RMS record with the version number Future versions of the app can inspect this value first and decide how to handle the data that follows Tip: The version number of your record can be different from the version of your app Maybe app versions 10, 13, and 20 all use the same record structure; if so, the records can share version number 1.

If you later change the structure, such as adding a Byline field to the NewsStory class as part of your changes to app version 21, you would increase the RMS record version number to 2..

One way to change the local declaration behavior is to embed the variable declaration in an eval statement, as shown in the following code modification: function AlwaysLocalScope() { info("AlwaysLocalScope{scopedVariable}", typeof(scopedVariable)); eval("scopedVariable = 'AlwaysLocalScope'"); info("AlwaysLocalScope{scopedVariable}", "scopedVariable=" + scopedVariable + " type=" + typeof(scopedVariable)); eval( "var scopedVariable;"); } The modified code with respect to the original AlwaysLocalScope code is in bold This time, both the assignment and the declaration of scopedVariable are dynamic, meaning that scopedVariable when assigned will be treated as a global variable This is because when the first eval statement is executed, there is no declaration of scopedVariable, and the JavaScript runtime will store scopedVariable in the global space To change the behavior and declare scopedVariable as a local variable, AlwaysLocalScope needs to be modified one more time, as follows:.

The PersistentStore and PersistentObject classes provide the capability to save application data. Unlike RMS, BlackBerry persistent storage is object-based rather than byte-based. This allows for more flexible and elegant coding. You store persistent objects based on a provided key. However, BlackBerry also tracks persisted objects by the application that created them. If an application is later removed, BlackBerry automatically deletes all persistent objects that are no longer accessible on the device. BlackBerry tries to detect the compatibility of persisted objects. If you load a new version of the application that has the exact same class structure for the persisted objects, the previous data will probably be maintained. On the other hand, if the data in a class changes or its structure is significantly altered (for example, by adding, removing, or reordering many methods), the old data will be automatically removed when the new version is installed. Therefore, you should avoid relying on BlackBerry persistent storage for data that you will need to access in future versions of the app. Look at this as a convenience to speed program operation, not as a reliable storage system.
