Two nodelet overwrite themselves?

I run two nodelets of the same name. They subcribe and publish to different topics, but they define the same variables. Are these variables allocate twice, because I start the nodelet twice, or does one nodelet overwrite the other?

Thanks

Do you have any idea to load same kind of nodelet in one nodelet manager? I tried, but met same result as you, that is one nodelet published topics have twice data, the other didn't have any data

Assuming you didn't use any "tricks", so use standard member variables: each nodelet is independent of another, so each gets their own instance of your variables.

This is no different from other C++ classes you write: each object gets its own instance of all member variables. Nothing is shared, unless you specifically set things up such that they are.

Edit:

I run two nodelets of the same name.

Did you intend to write "of the same type"?

PS: note that this is not "special" for nodelets, it's essentially basic C++.
