How to get a size of a object

Hi
Anybody Knows how to get a sizeof a object in java,
Pls reply to this.
cheers,
Sen

That's a bit ambiguous...
If you are asking about the size of the object reference in memory, then it is defined in the JVM specification.
I suspect you are asking about how much memory a given object takes up - that's going to be a bit tricky, because objects point to other objects, etc...
Rather than trying to come up with a solution to the question, I'd like to ask exactly why you need this - that might help the forum to come up with a solution to the real problem. Sound good?

How to get the values of the objects inside an object??

Hi,
I am trying to write code to display name and memory usage of all session attributes, in a recursive way.
I suppose reflection is needed here, but I cant figure out how to get the values of the objects inside an object...
private void handleIt(String attributeName, Object attributeValue) {
     boolean isPrimitiveOrNull = ((null == attributeValue) ||
          (attributeValue.getClass().isPrimitive()));
     if (isPrimitiveOrNull) {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "}");
     } else {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "{");
          Field[] fields = attributeValue.getClass().getDeclaredFields();
          int lim = fields.length;
          String name;
          Object value = null;
          for (int i = 0; i < lim; i++) {
               name = fields.getName();
               //LOOK AT THIS LINE: !!!!!!!!!!!!!!!!!!!!!!!!!!!
               value = fields[i].get(obj); //I don´t know what 'obj' should be??
               handleIt(name, value);
          sb.append("}");
Any suggestions will be greatly appreciated...

I realized that massive int objects called MAX_VALUE, MIN_VALUE and SIZE where causing the StackOverflow, so I removed them from the analysis.
This is the resultant code. But I think it isnt accurate in calculating the real size of objects being got using reflexion.
Do you or somebody have any more suggestions?

Hi,
You can get it from "User" or "Shop" business object.
Try to get User or Shop Business Object as shown below.
BusinessObjectManager bom = (BusinessObjectManager) userSessionData.getBOM(BusinessObjectManager.ISACORE_BOM);
User user = bom.getUser();
char decimalNotation = user.getDecimalPointFormat().getGroupingSeparator();
If you are seeing "1,234.00" then above code will return "."
I hope this information help you to resolve your issue.

How to get the size of partition?

The following SQL will get the rows of the fact table & aggregation. But how to get the size (MB) of the partition. select * from $system.discover_partition_stat That should be doable, because in BIDS, we can see the size of a partition, but from which
view we can do that?

This is the best bet you have SELECT * FROM SystemRestrictSchema($system.discover_partition_stat ,DATABASE_NAME = 'Adventure Works DW' ,CUBE_NAME = 'Adventure Works' ,MEASURE_GROUP_NAME = 'Internet Sales' ,PARTITION_NAME = 'Internet_Sales_2003') Refer

How to get the size of a hard disk?

Hi,
As above, how to get the size of a hard disk by using Java.
Thanks you!
Alex

I would be interested in the answer of this question, too.
In core Java there is no way to find it out in a platform independent manner because of the hardware abstraction of the VM. So my only idea is to write a native library for doing this and colling it via JNI

How to measure the size of an object written by myself?

Hi all,
I'm going to measure the performance on throughput of an ad hoc wireless network that is set up for my project. I wrote a java class that represents a particular data. In order to calculate the throughput, I'm going to send this data objects from one node to another one in the network for a certain time. But I've got a problem with it- How to measure the size of an object that was written by myself in byte or bit in Java? Please help me with it. Thank you very much.

Hi,
While applying Support pack for HR (SAP ERP 6.0) I get SPAU prompt with message:
"The system detected that 10 of the repository objects in the Support Packages have been modified in
your system . Check whether you want to retain or restore these changes you have made. Fore more
info about performing modification adjustment see modification adjustment help..."
Now as I call SPAU i get the screen with following options:

Can someone guide me How to get list of modified repository objects in SPAU.
Thanks & Regards

Hi,
In SPAU you will get with modification assistence. just expand the subtree, and follw standard process .
This is to retain the enhancement. If there are any data dictionary related correction go to SPDD.

How to get event when any library object added to indesign doc?

I want to do some operation when any library object is added to doc. So please tell me how to get event when any library object is added to the doc. better provide some code snippet.

Daves61,
I need to clarify what kind of event you're interested in.
1. When you click once on page/spead widget in the Pages panel and only widget becomes selected. The layout window remains unchanged. OR
2. When you doubleclick on page/spread widget the selected master spread appears in the layout window.
In the first case you work with Pages panel.
Have a look to file PageTransitionsPanelObserver.cpp from SDK.
PageTransitionsPanelObserver::LazyUpdate()
In the second case you work with Layout window.

How to get the size of all InfoCubes and DSO's?

Hi all,
My client wants a complete list of all InfoCubes and DSO's in terms of size (no records but KB). This list of the Cubes / DSO's gives us a picture of the used storage per Area and can be charged. Iu2019ve seen some threats and looked into the possibilities of ST14 and DB02. ST14 provides the ideal list but with a restriction for the top 30 InfoCubes and the top 30 DSO's. Does anyone know how to get such a list for all InfoCubes and DSO's?
Thnx in advance,
Henk.

Hello Henk,
while I am searching for some performance problems in our BI, I tried to look through the new DB02 of BI 7.0. And there is a function which helps a lot creating lists of Cube, DSOs and so on:
Start DB02
On the left side find SPACE -> Additional Functions -> BW Analysis
A Doubleclick will give you a broad survey of the current memory disposition regarding BI/BW objects.
In the BW Area "Cubes & related objects" you can find Infocube E- and F-Facttable. Depending on the Compressed state of your cubes you will find more data in E or F. Just doubleclick on one of these Entries. In my environment currently F-Tables are more effective.
You will then get a list of all Infocubes with size.
You will have to this for E and F Tables and some up over the Infocubes. But, because this will show only the Cubes and not the partitions of the cube it will be much easier to handle than DB02OLD.
Perhaps this helps, because you did not mention your BW/BI release.
Kind regards,
Jürgen

How to get the size of file

Hi
I want to know the size of the file from Java. ie If i have 10 lines in that file each of 15 characters
then 10 *2*10=200Bytes is the size. How will i get this?
More over, if i am reading the 4 the line, how will get the info that I have read 3 lines =3*2*10= 60 bytes so far?
Regards
Sriram

This is from the JavaDocs on java.io.File
length
public long length()
Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.
Returns:
The length, in bytes, of the file denoted by this abstract pathname, or 0L if the file does not exist
Any of the read methods (except readLine()) on the many stream objects return the number of bytes read, simply accumulate these returns to know how many bytes have been read.
