class TEvePointSelector: public TSelectorDraw
TEvePointSelector, TEvePointSelectorConsumer TEvePointSelector is a sub-class of TSelectorDraw for direct extraction of point-like data from a Tree. TEvePointSelectorConsumer is a virtual base for classes that can be filled from TTree data via the TEvePointSelector class.

Function documentation
TEvePointSelector(TTree* t = 0, TEvePointSelectorConsumer* c = 0, const char* vexp = "", const char* sel = "")
Constructor.
Long64_t Select(TTree* t, const char* selection = 0)
Process tree 't', select points matching 'selection'.
void TakeAction()
Callback from tree-player after a chunk of data has been processed. This is forwarded to the current point-consumer.
