The BlackBerry object Handles and the persistent object Handles?

Can someone please what are the object Handles and handles of object persistent in Blackberry? and how are they different?

Object handles are pointers to a Java object.  Each object that you create in your application using one of them.  Similarly, each object stored in the persistent store contains a handful.

If you have a complex object you want to store in the persistent store, as a vector that contains a number of complex classes, you can store the vector in a group of objects that you want to save the object handles.  Grouped objects use a single Treaty when it is stored in the persistent store.  The disadvantage is to ungroup the object for editing.

You will need to balance saving handles object against the drop in performance of separate objects.  Object groups are ideal for the complex elements that are frequently changed.

  • Editing an object that I stored in the persistent store

    I store a custom object in the store persistent and would like to add a new Member.  Someone knows how can I do this?  I'd rather not delete it and store an object in its place because what happens if I need to add more members in the future.  This would encourage me to juggle all versions of my object.  Is there a kind of model for version control that I can apply to my objects stored persistently?

    I don't think it will work.  The link that you say talk us too much serialization, but the persistent object is not serialized as part of persistence.  If you want to serialize her, you should do it yourself.

    I'm guessing that you did not design your class being "expandable". And I'm guessing that you do not want your users to have to recreate these data.

    So I investigate an approach to migration.  In the code that gets the persistent store, got it get the object persistent, then check that it is indeed a picture of your old items.  If it is, convert it to an object type, store it in a collection (vector or Hashtable as suggested, for example) and keep the result, by replacing your old array of persistent storage object.  So your new application includes the old class of objects, exactly as it was, which means that you can install it on top of your existing application.  But once your request is used at the same time, the old persistent object is no longer used.

    Does make sense?

  • Doubt about the persistent object

    Hi friends,

    I've stored data object persistent after that some time, my Simulator has taken a lot of time to load the application so I run clear.bat do fast Simulator. But after I run clear.bat. The values of what I stored in the persistent object had disappeared. Someone at - he said, therefore, it is the persistent object data are parties to cause of the performer, the clear.bat or any other reason. pls clarify my doubt friends...

  • SE connect Blackberry 10 Simulator and BBM works does not in the Simulator

    Hi all

    I use QNX momentics IDE for development and blackberry 10 Simulator.

    I use the simulator using VMWare workstation. A problem that occurs is that my Simulator is impossible to connect to BBM. Although the Internet is there on Simulator (checked with the browser on Simulator). As far as newspapers are concerned in the case of the blackberry simulators 9900 and 9930 counted out newspapers and event logs.

    But in this Blackberry 10 Simulator, I could not find newspapers where they are generated.

  • Differences between the version of BlackBerry Device Software and platform. Help, please...

    Hi guys!

    I'm really confused... Help, please!

    We have developed applications for our customers. We tested with our BB8700 and it works fine.

    We used JDE4.2 for development... and we think that it will work on v4.2 based handsets.

    But our customers wrote that it works on v3.7. Why? Is this possible?

    I looked at the information about my 8700 device and then noticed: v4.2.1.107 (platform v2.3.0.84)

    -What are the differences between the version of BlackBerry Device Software and platform?

    Possible customers spoke of version 3.7 of the platform?

    There is a list of the devices, where we can find the version of BlackBerry Device Software by BlackBerry device model?

    Or where we can find information about the models of devices that will support our application?

    Thanks in advance!

    AFAIK there is no version 3.7 platform.

    Customer talking about the OS version.

    So, if they have the device OS version 3.7 you must use JDE JDE 3.6, 3.7 or older.

    Or take updated device OS if the necessary software is available.

    Error commissioning took place for Machine xxx: View Composer agent initialization failed

    I am currently deployment of VMWare view for the first time in a test environment and have hit a problem I have not been able to get around despite several searches on google and trial and error.

    Hoping that someone here could suggest something.

    View the VMWare versions are all 6.0.1.

    vCenter is on a device.

    VMWare view connection manager is on a 2012 R2 VM server.

    VMWare view dial is on a separate server 2012 R2 VM.

    I have a 2012 SQL on a separate server 2012 R2 VM Server installation.

    SQL databases have been set up for the composer to be able to reach it, it uses ODBC 64-bit via SQL Server Native Client 11.0.

    I tried troubleshooting by exchanging 32-bit, but this is not connected, it seems so 64 bit is correct.

    I have a windows 7 64-bit Enterprise Edition VM under my Golden image. There are VMWare tools on it and the VMWare agent on it.

    The virtual ipconfig/release performed top machine, he was then stop and a snapshot taken as my source.

    The problem is that when I go to deploy a pool of offices, I get the above error.

    If I connect to the VM created via vCenter readers persistent and temporary show very well.

    Based on the error, I tried different settings such as change the path for the reader of DVD VMs of D: to Z:, spread unique persistence and the temporary disks on multiple data-stores or data stores and even remove the drive of DVD of VMs completely. I have also looked at newspapers under composer view but find nothing to explain the behavior.

    SQL Server seems to work for configuration through the error logs and virtual machines are created and added to AD as expected.

    I must point out that the virtual machines are as linked clones.

    Can anyone offer a clue as to the cause or something, I can check it please, did everything I can think and Googling the error does not come to the top with something useful so far.

    Thank you

    I'm developing a smartphone application that will create a persistent database to store the data.  But I want to initially load the database.  Does anyone have suggestions as to the best way to do this?

    I suspect delete cod, you will need to provide in a separate application, i.e. a separate alx, or download the jad file separate of OTA.

    Is not a snippet of code to remove a cod, have a look round I think remember me someone on this forum Announces some.

    Here's a code snippet that shows if a cod is present and if so, use it.  This cod contains only data, a little as you want.  In this case, the data is XML, which the application takes a string and then analysis.

            String moduleName = "";
            int handle = CodeModuleManager.getModuleHandle(moduleName);
            if ( handle != 0 ) {

  • Remove the persistent about uninstalling storage

    Thank you...

    If you use Vector, instances of the string class to store data in the store persistent it will remain after application is uninstalled.

    But if you store instances of your classes like:

    class MyStorageBlock implements {Persistable

    private String myData;

    ...........

    }

    all of these objects will be deleted when your application is uninstalled.

    Yes, vector will be better because you can't copy items.
