How to find which objects use most of the memory

anakreon

Hello.

Is there any tool which could help finding out which objects consume
most of the memory?

I was thinking something which would generate a report like:
ClassA 120003 instances 3MB
ClassB 4550 instances 1MB
and so on.

I used massif of valgrind but it doesn't do what I need.

Thanks for your reply

Tools: No idea.

If you asking about the class size, then use sizeof operator, count your
object. Sccot Meyers has article on this issue, check out his homepage
If you meant there are pointers inside of classes, and you want to add
the size of what the pointer points not add the size of an pointer, it's
more complicated, not only the pointer issue, but also some recursive
calculation; as an clue, you have to apply some extra mechanism shipped
with you platform, like VC, we can use _CheckMemState. But I think it's
hard.

You can probably get information like that from a better profiler, using
the right settings.

Persistent objects

by: Paul Rubin | last post by:

I've had this recurring half-baked desire for long enough that I thought I'd post about it, even though I don't have any concrete proposals and the whole idea is fraught with hazards. Basically I wish there was a way to have persistent in-memory objects in a Python app, maybe a multi-process one. So you could have a persistent dictionary d, and if you say d = Frob(foo=9, bar=23) that creates a Frob instance and stores it in d. Then if...

Storing objects in vectors - what's wrong with this code?

by: Alfonso Morra | last post by:

I have written the following code, to test the concept of storing objects in a vector. I encounter two run time errors: 1). myClass gets destructed when pushed onto the vector 2). Prog throws a "SEGV" when run (presumably - attempt to delete deleted memory. Please take a look and see if you can notice any mistakes I'm making. Basically, I want to store classes of my objects in a vector. I also have three further questions:

A deque containing different types of objects (with a common baseclass)

by: Juha Nieminen | last post by:

I'm sure this is not a new idea, but I have never heard about it before. I'm wondering if this could work: Assume that you have a common base class and a bunch of classes derived from it, and you want to make a deque which can contain any objects of any of those types. Normally what you would have to do is to make a deque or vector of pointers of the base class type and then allocate each object dynamically with 'new' and store the...

map<float, T>::find

by: Rares Vernica | last post by:

Hello, How does find works for a map where the key is float? I know you cannot just simply compare floats for equality, you need to use fabs and some epsilon. I know map does not use equality, but uses "less". Still two floats (float a,b;) might show as a b when in fact they are equal. I am a bit confused.
