TParameter for string?

ROOT
1

Hi Rooters,

Is there something like a TParameter?
I’m already using TParameter to safe some values in a TFile.
In addition to that I would like to safe a string as well.
Does anyone have an idea on how to do that?

Cheers,

Christian

Hi Christian,

You could use TObjString …

Hello Philippe,
thanks for your answer.

TObjString looks like a interesting option. The problem is that TObjString doesn’t have a name.
The string in the object is used as name and value.

In my case I wanted to safe the version of the software which created the root file in the file it self.
Therefore I wanted to create an object with the name “version” and a string value.
Unfortunately this is not possible for TObjString.

Are there any other options to save a sting value with a name in a TFile?

Thanks for the help

Christian
