Saving std::function

ROOT

Hi, Experts
Is it possible to save std::function as an member of TObject?
I tried to save class with std::function < double(TLorentzVector*)>, code is compiled but when I trie to save object I get errors and warnings:

Warning in <TStreamerInfo::Build>: _Maybe_unary_or_binary_function<double,TLorentzVector*>: base class unary_function<TLorentzVector*,double> has no streamer or dictionary it will not be saved
