• "Garbage collect from."

  Hello:

  Have we never saw the message "Garbage collect from" on the JDE title bar when Simulator starts up.

  It lasted all night.

  And I also tried to change the model of simluator, the problem still exists.

  Thank you!

  Thanks Mark, it works now

• Does garbage collection occurs in the region of PERM of Java Heap?

  Hi guys,.

  I am a new Member to this forum, my name is Javin Paul and I'm a Java programmer. I have a question related to the garbage collection in Java

  Does garbage collection occurs in the region of PERM of Java Heap?

  According to my knowledge PERM area is used to store metadata about classes, methods, variable etc also string Pool created in PERM area of the heap, so I believe that garbage do not occur in this place, but I just wanted to know what you guys think of it?

  Thank you

  Basics segment of memory and so on that you are used to, do not apply the FMV of Blackberry - well they probably not, but it is well hidden from us.  I recommend you check out this video to understand what you can control re garbage collection operation.

• Restarting the device on the garbage collection

  Hello

  I created an application that performs the following operations:

  1. Read an email address of a BasicEditField that an end user will be input.
  2. Convert this string to an object of net.rim.blackberry.api.mail.Address
  3. Persist the object address by doing a commit sync
  4. Read the persistent object even to intervals and use it to send email.

  I am able to record the e-mail to the PersistentStore address.  When I get out my app running (for sending electronic mail timed) so the device restarts.  After a reboot, the device remains stable and emails come out because they are supposed to.

  I am now able to reproduce this exact behavior if I first enter the e-mail address, it persists and call a GC (garbage collection).  As soon as I do this, the device restarts.  As a tip, I also did a forceCommit() rather than a commit() and there is no difference.

  I tested the following physical devices:

  Bold 9700 - v5.0.0.862 (1446 Bundle, platform 5.1.0.175)

  Torch 9800 - v6.0.0.246 (695 Bundle, platform 6.4.0.150)

  The same behavior is exhibited in both devices.

  I don't think any of you have already encountered this?  I was not able to understand why this is happening and it has been driving me crazy.  If you've seen behavior like this and have either thought about it or not, please answer.  Thank you!

  Imagine that... Address is not persistent.  Could have fooled me because once or twice, the program worked by reading the object address of is.  The behavior seems to be inconsistent.  I have changed my address object in a string and now everything works fine.

• How different modes of garbage collection?

  On http://na.blackberry.com/eng/devjournals/resources/journals/jan_2005/garbage_collection.jsp#programm... there are two modes of GC listed, but only a single API to perform the full pass. Is it possible to run a past further by programming? Thank you!

  As I said, the only way that you are able to instruct the JVM garbage collection is through the System.gc method. There is no other way around it - this, I think, is the same thing with J2SE as well.

• Garbage collection

  If the garbage collector is called by an application, it works in the background or in the thread called? Is it possible to profile in the JDE memory while an application is running?

  I think that you will find this video very useful.  He explains more about the garbage and shows the determination of the characteristics.

• Run garbage collection operation in AIR - iOS app

  Just to be in a bit of a learning curve, develop a Flash application for browser used in a browser and set up with the memory management optimal if all goes well using Flash Professional CS5.5.

  Part of the process is to make sure that the object have no reference pointing of the finger when they are made with so much garbage can clean them.

  Now, I came to the port of the application on iOS for iPad. My question is... Air for iOS, run the garbage collection?

  Thank you

  Mark

  Yes. and you can manually force garbage collection by calling System.GC() If you use Air 3.0

  but try not to rely too much on the gc to solve memory problems... too much to clean up causes a very noticeable lag when running, and it does not work in any foreseeable calendar I can say... If your memory get is too high, your application can be ejected and crash.

  something to keep in mind, recycle and pool objects and varibles as much as you possibly CAN... try using the NEW keyword as little as possible... then all killed during a phase transition or loading followed a system.GC() if the offset is not noticeable.

• How to prepare list for garbage collection after drag and drop operation

  Hi all

  I have a view in a mobile application that contains a list with the help of drag / move. The problem I encounter is that the NativeDragManagerImpl maintains a reference to this list in its _dragInitiator and _relatedObject properties. It is not a memory leak by - say, because the reference will be replaced the next time make drag and drop is used, however, my view that preclude any garbage collection, causing an unacceptable peak memory.

  Here is an example which illustrates the problem (app default AIR using Flex 4.5.1):

  Main.MXML

  <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:local="*"

            </s:List>
  </s:Group>
  
  

  If you drag items to the list on the right, there is always at least one instance of ListGroup stuck in memory for the duration of execution (as seen in the profiler).

  Is there a way to perform cleanup on the DragManager (or in fact the underlying DragManagerImpl) upward to a time of my choosing? Thoughts or ideas will be greatly appreciated!

  Thanks a lot for your time!

  I think I'd be monkey-patch NativeDragManagerImpl.  And create a bug report.

• Issue of garbage collection

  Hello

  Let's say you create a dynamic movieClip and also dynamically add an event listener.  Then you addChild clip.

  Now comes the time to get rid of it - you want to get rid of the object and its event listener.

  Would be...

  
  

  removeChild (my_mc);
  my_mc = null;

  remove the object, and it is the event listener, or would need to also add:

  my_mc. removeEventListener (MouseEvent.CLICK, doWhatever);

  What I'm trying to do is to have a close button on each movieclip that when clicked, performs a function to remove the clamp and his children to appear and also remove references to it so that it can be ready for garbage collection.

  Thank you

  Shaun

  Hi shaun

  Yes, you should not remove the event listener yourself unless you use a 'low' (5th argument of addEventListener set to true)

• Some Garbage Collection issues

  I searched the Garbage Collection, and I still have some doubts. Consider the following code:

  var objt:Sprite = new Sprite();

  var child: Sprite = new Sprite();

  stage.addChild (obj);

  obj.addChild (child);

  obj.addEventListener (MouseEvent.MOUSE_DOWN, onMouseDown, false, 0, true);

  child.addEventListener (MouseEvent.MOUSE_DOWN, onMouseDown, false, 0, true);

  Suppose I want to get rid of (delete, delete, destroy, purge, KILL >: D) everything about obj (itself, its events, its children and its event listeners listeners). Is the following code enough? :

  stage.removeChild (obj);

  obj.removeEventListener (MouseEvent.MOUSE_DOWN, onMouseDown);

  Delete obj;

  Yes.  shortly after this code executes both obj and child will be gc would have.

  You call unload() on objects that you cancelled - where the error.

  You should do something like:

  {if (loader2)}

  loader2. Unload();

  }

  As for the null value passed into the function - null is a default value. In this way, you can call the low past nothing:

  Down()

  Or you can use it as a handler in which case it will be called by the Auditor:

  Down (mouseEventInstnace);

• Script for garbage collection in Captivate 4 Widgets?

  Hi guys and girls

  I'm having a problem with some custom widgets that I made. I have a number of widgets on every slide in my project (which are reused on each slide) and they work fine... BUT I noticed that when the project is published and played the executable starts eats more RAM. I noticed that the EXE eats more RAM at the beginning of each slide and never decreases.

  I think what is happening is that even though im using the same widget on each slide, Captivate load a new instance of the widget to each new slide and no garbage collection on the previous slide widgets. Does anyone know of an ActionScript command in order to solve this problem? Or a work around?

  A question for adobe... Do you know the guys on this problem? and if yes, do you intend to fix in an update?

  See you soon

  Aquil0

  Hi Aquilo,

  The reason for the consumption of RAM is usually because something in your code has not been unloaded, always raises an event or a timer still work and Captivate continues to run and store it in memory, despite a change of the slide or the off-screen image disappear.

  Best option is to add a feature to "unload" to your flash widget that will destroy everything.

  Here is an example applied to a loader (Actionscript 3) object

  loader.addEventListener (Event.UNLOAD, unLoadHandler);

  function unLoadHandler(event:Event):void {}

  Kill the charger

  var loader: Loader = Loader (event.target);
  Loader.Unload ();
  Charger = null;

  Remove event listeners

  this.removeEventListener ("onEnterFrame", onEnterFrame);
  this.loader.removeEventListener (Event.UNLOAD, unLoadHandler);

  Stop all timers

  Timer.Stop ();
  }

  Note how I put the "loader", NULL, after unloading it - this will ensure it comes out of the memory, as Flash Player 9 has an error where it won't completely remove something of memory, although it is being unloaded.

  Hope that helps.

• Garbage Collection, external swf and XML

  I did tons of research on the AS3 garbage collection. I have a decent knowledge of it, but I CAN'T find any info about the deletion of xml data. The worst thing is, I have no control over the version of the file (AS2 or AS3) swf file I'm loading. Unfortunately, I'm loading AS2 swf (with an outside provider that will not show you any code) in a film of AS3. When I run garbage collection, the data from the xml file / is not deleted and I can't understand how get rid of it. The problem is, once a file is loaded which calls an xml file, no other files cannot load an xml.
  
  If anyone knows how to clear the XML, please fill me in.
  
  Thank you!

• Associative array and Garbage Collection

  Hi all
  is there any concept of garbage collection in the use of an associative array?
  
  When I create an associative object instance is there any provision in oracle to release and drop this object
  in memory after use?
  
  Thank you
  Charles

  Not sure; Why would you want to?

  Oracle manages this kind of thing very well; It is not something I've ever had to consider, really. Even if Oracle does not clear the memory allocated immediately, I am sure that it is marked as available for reuse.

• Interpolation and Garbage Collection problem

  No matter what I I can not solve a problem with AS3 Garbage Collection of tween I'll have it is havoc on my tween instances works correctly/consistently. Some Sprites never tween at all, some do it but only part way. And it different effects almost every time.
  
  I recently read about AS3 Garbage Collection and badly referenced interpolations and other asynchronous forums is picked up in the Middle process fairly. I feel the inconsistent behavior of signature that the I have read.
  
  I tried to use the static properties level and not static class to store the references to my Tween instances so that they will not be shown for the GC. No luck. I placed references to these in the class-level tables, I also used static to() TweenMax method, which ensures that there will be the shield of GC and its static constructor instantiation not alt., with persistence: true. I have also set up another package custom; GCSafeTween(), others says it's as it should be, but it does not work in my case.
  
  To test the GC problem, I edited the two eventListerners() in the Adobes fl.transitions.Tween so that their default weakReference property was false. This is properly the work of Tween. But this is a terrible solution.
  
  Here is my code. Its a bit stripped down just to show the configuration.
  Thank you for helping me solve this one!
  
  
  

  The problem is finally solved.
  I had another Alpha tween StackDisplay targeting a Sprite that is nested inside the main Sprites that I tried to tween Alpha. I noticed that if I planned other properties of the target Sprites they work always as interpolated. It was only the Alpha which would get stuck from time to time.

  JPSoul thanks for helping me to tackle the problem in a different way and get finally resolved.

  FYI here is the line that caused the issue:
