[ROOT] Accessing member functions from a TTree...

I would like to fill a Tree with LorentzVectors.
Then I need to access their data via the member functions, i.e. X(),
Phi(), etc. and plot these values.
Is this possible? Is there a simple example out there I can follow to do
this?
I think I am filling the tree properly, but I seem unable to access any
of the data once I do so.
Any help would be greatly appreciated.
Thanks.
