Hi,
New to TPTP but not Eclipse or Java. I'm trying to use TPTP to see the memory usage of my app, but I am not seeing all the objects.
Platform
Windows 7 (64-bit)
Eclipse 3.6.2
TPTP 4.7.1
TPTP was installed via the Eclipse "Add new Software" option.
I've spent about 2 hours looking over the TPTP site and couldn't find anything relevant.
Anyway, I made a simple Java app and profiles it. The app consists of a class which has an ArrayList memory in which I create 100 strings and place it in that ArrayList. When I run the application via the "Profile profile Test", I setup to do "Memory Analysis" and I also check the "Track object allocation sites". The program runs and look at the Memory Statistics and all it shows in the class itself, with 1 allocation and a size of 16. It doesn't show any information on the strings or the array list.
As an additional test I also allocated an ArrayList in the 'main' function and added strings to that and still they do not appear on the memory stats page.
Can anyone tell me what I am doing wrong?
Here is the simple program I tried:
public class ProfileTest {
private List<String> strings;
public ProfileTest() {
super();
strings = new ArrayList<String>();
}
private void addStrings() {
for (int x = 0; x < 100; x++) {
String str = String.format("%03d", ((int)(Math.random() * (double)x) + 1));
strings.add(str);
}
}
/**
* @param args
*/
public static void main(String[] args) {
ArrayList<String> foo = new ArrayList<String>();
String f = new String("WTF!");
foo.add(f);
ProfileTest t = new ProfileTest();
t.addStrings();
}
}
In terms of TPTP the "Memory Statistics" has one row populated which says:
Class Name Live INstances Active Size
ProfileTest 1 16
There is also a Total Instances & total Size colums which have the same values and finally a Avg Age column which has 0 in it.
In the Allocation Details tab it shows Method as Main line no, class Profiletest and the live instances, Active size etc....
Any help appreciated
