Save object in memory

Hi all,
i have to save an instance in memory because i need the information later.
The Programm goes like this:
1) Get instance1
2) call sap-classes and methods
3) create instance2
4) Call function to show instance2
5) Start BDT functions. And at this point i loose my information about instance1
how can i write the instance1 into "global memory" for accessing all data all the time?
Thanks
stefan

Hi Stefan,
If you want to save an instance of a class in memory, you can use persistent classes.
Generally ABAP programs work with data and objects that are valid at
runtime. They are transient i.e. temporary and disappear when program ends.
To store this data permanently and independently of the program context,
i.e. persistently, it must be stored in the database. This means instances of
global classes can be written to database tables.
Persistent Services in ABAP Objects can be used to write the current attribute
values of objects defined as persistent to associated transparent tables.
On request, these values can be imported from the tables and assigned to an
object previously defined as persistent.
To use persistent services for objects, their types must be created as
persistent classes in Class Builder.
Send me your mail ID so that I can pass you a document on creation of persistent classes.
Award points if found useful.

Save a big memory object to fi

Hi, in my App, I have a image which may be as big as 8M bytes. I would like to save it to a file to iphone local disk. I know I can make it to NSObject (or NSData?). My questions is how can I set the path of this file.
thanks,

Serializing an Object:
try
ObjectOutputStream myOutput ObjectOutputStream(new FileOutputStream("objects.out"));
myOutput.writeObject("Hello! How are you on this very fine day?");
out.close()
catch(IOException e)
System.err.println("Doh! You're probably writing to a file that you don't have permissions to access!");
catch(ClassNotFoundException e)
System.err.println("You should only get this if you're using some strange reflection stuff, or just try to output something that doesn't exist.. I don't really know why the compiler wouldn't catch this error instead otherwise");
Getting that object back:
try
ObjectInputStream inObjects = new ObjectInputStream(new FileInputStream("objects.out"));
String myObj = (String)in.readObject();
System.out.println(myObj);
Pretty simple. If you want to be more practical, and store more than one type of object in that file, you can use relfection:

Reading Lots of Objects into Memory

I need to read thousands of fairly large objects from an object database to the point that the JMV memory runs out.
A solution is to: read, use and discard as opposed to loading all the objects into memory at once -pretty simple but I want to do it right. I have a general idea on how to implement the approach but I need your help in locating some reading materials, code snipplets and/or best practices.
Thanks!

If you're using thousands of objects you might look into the Flyweight Pattern (depending on what these objects are and what state they have). You might also look into increasing the amount of memory available to the JVM via that -Xms switch.
Aside from that, if you reuse the same reference name (variable name)(s) you'll allow the Garbage Collector to recover that memory.
Good Luck

Compare system state (number and types of objects in memory)

We have 2 exactly identical servers running our application talking to the same database.
When some obejct from server 1 is deleted, a message is passed to server 2 to delete the object from its cache too.
Forget the database, I want to design a testing system which compares the system-state (number and type of live-objects) in memory for server 1 and server 2 after the operation and the message, and reports any discrepancy.
Any ideas ?

Are you trying to debug a distributed cache implementation?
If you want to inspect the state of your application on multiple servers creating a JMX bean might be a solution.

How to remove the Object from memory.

Hello.
Flash file that i made with Flex Builder uses memory too
much.
Look at the next example source code.
var testCan:Canvas = new Canvas();
this.addChild(testCan);
this.removeChild(testCan);
testCan = null;
but just memory usage still goes up, is not freed instantly.
so if i load the large flash files on my web browser,
after 5 munites or something, the web browser is down.

delay?

How to export & import interface type data object to memory

Hi experts,
My greetings to all.
we have came across a situation where we need to pass interface type data object to memory
and import same from memory.
DATA context TYPE REF TO if_timecontext.
its not possible with regular export statement.
is their any other way to do it?
Thanks in advanced,
Sudhir

Thank you saurabhmani & sandra.
@ saurabhmani : i tried assigning object context to memory (field-symbol) and exporting it to memory, but got runtime error.
@sandra : XML serialization & shared object concept sounds intresting but as you already checked that interface IF_TIMECONTEXT is missing the required IF_SERIALIZABLE_OBJECT interface.
Istead of exporting context data object to memory we tried different approch and it worked out for our requirement

Object allocations, memory and UINavigationController

I'm having a problem with object allocations
Is it possible to release/remove a view from a navigation controller stack when I click on the back button on my navigation controller? I wish to get rid of the view I just left (the one disappearing to the right of the screen). The problem is that the next time I navigate to the same view lots of new objects are allocated, and none of the old ones are released.
In the tableView:didSelectRowAtIndexPath: method I initialize a new view controller for the view I want to push to the stack and assign it to a property. The problem is that the old view seems to continue to exist in the navigation controller stack, because it's never released according to the "object allocation" section in Instruments, thus the amount of allocated objects and memory just grows and grows as I click back and forth in my navigation controller.
For example, if I click on a cell in the first table view (which displays a second view) and then click on the back button and then click on the first cell again, the second view and all of its objects are created again, but the previous instance of this view seems to still exist somewhere in the navigation controller stack.
What's the best way to solve this?
Here's some of the code in the "tableView:didSelectRowAtIndexPath:" method:
self.categoryController = [[CategoryViewController alloc] init];
self.categoryController.category = category;
[self.navigationController pushViewController: self.categoryController animated:YES];
Each time this code is executed tons of new objects are allocated, but the objects allocated by the previous CategoryViewController are not released.

Thanks you so much for the great article!!

HI All,
How to save OTF to Memory using this FM: ME_PRINT_PO.
Please let me know.

No, it should be there, becos inside that FM this fm is also calling, SAVE_OTF_TO_MEMORY. but it is calling in Enhancement point. im not able to put the break point there. i think that code is not executing.
im getting this error: Breakpoint not set since enhancement ISAUTO_SCH_EMM_SAPLMEDRUCK is switched off.

Save objects in ATG

Save objects in ATG:
Hi,
I was recently being interviewed for an ATG job which involved custom development. I was asked to describe the development that I did. When I mentioned that I used RQL to persist data in repository items, the interviewer broke in with "RQL?" I said "yes RQL" and then there was a long silence. She then replied "why would you use RQL? in ATG you just save objects" I don't know what she is referring to, can anybody explain what she meant?

Yes, there are different methods that can be called to persist your changes.
- MutableRepository.updateItem() is called to update an existing items and is used in conjunction to MutableRepositoryItem.setPropertyValue()
- MutableRepository.createItem() followed by MutableRepository.addItem() is called to create a new item
- MutableRepository.removeItem() is called to delete and existing item

How to save object to SQLite?

Hi,
I am confusing with this.
How to save object (instance of class) to SQLite and read the
object back to Flex?
Thanks
Mark

SQLite is a relational database, not an object-oriented
database, so you can't just spit an object into it without
translation. You
could serialize it with JSON or XML and store that in a
column, but then you're giving up most of the benefit of a proper
database engine. It's best to flatten the object yourself into the
database structure. How you do that, exactly, depends on your
object structure(s).
So, if you have an object like this:
var foo:Object = { bar: 'qux', bletch: new Date(), farbly: [
42, 69 ] };
you probably need two tables to represent it: a main "foos"
table (a collection of foo objects) and a separate "farblys" table
to hold the array elements. This separation of arrays out into a
table of their own linked to the original table is called
normalization.
Normalization will be covered in any decent tutorial book on
SQL databases. You'll need to get one to best understand how to
utilize SQLite, or anything like it. I got a lot out of
The
Practical SQL Handbook. I doubt that it covers SQLite
specifically. I have an older edition, so I can't check, but the
current edition was released about the same time that SQLite was,
and SQLite took some time to get noticed. The
SQLite Documentation
will fill in the gaps. The main thing to beware of is that SQLite
doesn't support all the advanced things you will read about in a
general SQL book.
If you don't want to mess with all this object-relational
mapping and normalization stuff, and you don't have much data to
store, you might look into Flash Local Stored Objects (LSO), also
called "Flash cookies". The runtime has a default limit of 100 KB
of data per application. The advantage of LSOs is that you can use
them like any other ActionScript object, and Flash handles the
storage details for you. It's great for configuration data and
small bits of user data.

Exception Thrown when trying to save object to disk

Alright,
So I've got an object that looks like this
private class InputData implements Serializable {
            public String name = "";
            public String condition = "";
            public String value = "";
            public String[] productTypes = new String[]{};
            public String[] ticketStates = new String[]{};
            public String fieldName = "";
            public String startDate = "";
            public String endDate = "";
            public String dateRange = "";
............................It has two constructors and overrides the toString() method. I'm trying to save it to a file with the following
private void saveSearchesToDisk() {
            File f = new File(SAVED_SEARCHES_DIR, SAVED_SEARCHES_FILE);
            InputData[] data = ...
            try {
                FileOutputStream fos = new FileOutputStream(f);
                ObjectOutputStream oos = new ObjectOutputStream(fos);
                oos.writeInt(data.length);
                for (int i = 0; i < data.length; i++) {
                    oos.writeObject(data);
oos.flush();
oos.close();
fos.close();
}catch(FileNotFoundException e) {
e.printStackTrace();
catch(IOException e) {
System.out.println(e.getMessage() + " hi hi hi hi");
e.printStackTrace();
I'm getting this exception, and I have no idea why???
java.io.NotSerializableException: com.sun.java.swing.plaf.windows.XPStyleAny ideas?

I think you are misunderstanding something.
The reason why the outer members are being serialized, or attempted to be serialized, is because of the inner object's hidden link to the outer object. So the outer object is reachable from the inner object, and the outer data members are reachable from the outer object. There is no hidden link from the inner object directly to the outer object's members if that's what you're talking about. So there is no need for the notation you are talking about and so it doesn't exist.
So the question remains, do you want the outer object serialized or not?

Releasing Objects from memory-Performance improvement

First Javafx was excellent in coding on UI rapidly. We did a image application and it was fine with some small memory tweaking pending. Since we have binded variables from static file to all objects, i think the memory of objects removed or deleted is not getting released. Is the there any way to unbind or destroy the objects which are binded. I think the the next release of Javafx will have a better performance.Any ideas or suggestions will help us to improve the performance drastically. Any help on this regard is highly appreciated. Thanks in advance.

Thanks Keap for your reply. Since we have used bind extensively, let me tell scenario the where we have used binding. We used a static class in javafx. Many variable in static class has been binded to javafx objects. Since the variable of javafx objects are binded to stastic varaibles, i doubt even after after not using the objects they are in the memory, because of the binding reference. since i dont have control of the static file scope, the objects are in memory and the app throws out of memory after sometime.We came forward with solution ie to use the conditional binding. I need other experts comments before proceeding as it needs lot of refactoring. I like to know whether the following statement
"var a = bind if (condtion) c else d" (note: c is a variable in static class eg MainStatic.c)
will deattach the binding of "a"with the the static file variable.
As this issue blocking, we need a solution to improve it. Any help on this would be highly usefull.
Thanks in advance

I have a 5300 but nothing saves to the memory card...

I've just bought a 5300 with a 2gb memory card, but all the music & pics i put on it seems to save to the phone & not the card. Have only got about 5 mp3's on it & says memory is full! Does anyone know how to fix this???? Thanks!!

Whenever you transfer anything,just use the DATA STORAGE(Drag&Drop Facility)not the Nokia Mode.
