A TSelector object is used by the TTree::Draw, TTree::Scan, TTree::Process to navigate in a TTree and make selections.
It contains the following main methods:
WARNING when a selector is used with a TChain:
in the Process, ProcessCut, ProcessFill function, you must use the pointer to the current Tree to call GetEntry(entry)
. entry is always the local entry number in the current tree. Assuming that fChain is the pointer to the TChain being processed, use fChain->GetTree()->GetEntry(entry);

Abort processing.
If what = kAbortProcess, the Process() loop will be aborted. If what = kAbortFile, the current file in a chain will be aborted and the processing will continue with the next file, if there is no next file then Process() will be aborted. Abort() can also be called from Begin(), SlaveBegin(), Init() and Notify(). After abort the SlaveTerminate() and Terminate() are always called. The abort flag can be checked in these methods using GetAbort().

static |
The code in filename is loaded (interpreted or compiled, see below), filename must contain a valid class implementation derived from TSelector.
If filename is of the form file.C, the file will be interpreted. If filename is of the form file.C++, the file file.C will be compiled and dynamically loaded. The corresponding binary file and shared library will be deleted at the end of the function. If filename is of the form file.C+, the file file.C will be compiled and dynamically loaded. At next call, if file.C is older than file.o and file.so, the file.C is not compiled, only file.so is loaded.
The static function returns a pointer to a TSelector object
