Filter the member list obtained from a TObject

[Javier_Galan]

Hi there,

this question is a kind of extension of this previous post from long time ago.

Get a list of member in a class deriving from TObject

Hi there, just a very basic question. How can I get a list of the member names inside the TObject class? I.e. the first column when using method ->Dump() thanks!

I am interested to get a list of members, but only those members that are actually stored/written to disk. I.e. those members that end with //< and discard those that end with //!.

Once I get the list, for example using

TList *list2 = run->IsA()->GetListOfDataMembers()

how can I filter this list to get only those members, which are registered when using the ->Write method?

Hi Javier,

I think you can achieve this with the TDataMember::IsPersistent() method: https://root.cern.ch/doc/master/classTDataMember.html#a348271bbf5bd6989e59208e8a5d49504
