class TEventList: public TNamed
A TEventList object is a list of selected events (entries) in a TTree A TEventList is automatically generated by TTree::Draw: example tree->Draw(">>elist1","x<0 && y> 0"); In this example, a TEventList object named "elist1" will be generated. (Previous contents are overwritten). tree->Draw(">>+elist1","x<0 && y> 0"); In this example, selected entries are added to the list. The TEventList object is added to the list of objects in the current directory. Use TTree:SetEventList(TEventList *list) to inform TTree that you want to use the list as input. The following code gets a pointer to the TEventList object created in the above commands: TEventList *list = (TEventList*)gDirectory->Get("elist1"); Use function Enter to enter an element in the list The function Add may be used to merge two lists. The function Subtract may be used to subtract two lists. The function Reset may be used to reset a list. Use TEventList::Print(option) to print the contents. (option "all" prints all the list entries). Operators + and - correspond to functions Add and Subtract. A TEventList object can be saved on a file via the Write function.

Function documentation
TEventList()
Default constructor for a EventList*-*-*-*-*-*-*- *-* ==================================
TEventList(const char* name, const char* title = "", Int_t initsize = 0, Int_t delta = 0)
Create a EventList. This Eventlist is added to the list of objects in current directory.
void Add(const TEventList* list)
Merge contents of alist with this list. Both alist and this list are assumed to be sorted prior to this call
Bool_t ContainsRange(Long64_t entrymin, Long64_t entrymax)
Return TRUE if list contains entries from entrymin to entrymax included.
void DirectoryAutoAdd(TDirectory* )
Called by TKey and others to automatically add us to a directory when we are read from a file.
Long64_t GetEntry(Int_t index) const
Return value of entry at index in the list. Return -1 if index is not in the list range.
Int_t GetIndex(Long64_t entry) const
Return index in the list of element with value entry array is supposed to be sorted prior to this call. If match is found, function returns position of element. If no match found, function returns -1.
void Intersect(const TEventList* list)
Remove elements from this list that are NOT present in alist.
Int_t Merge(TCollection* list)
Merge entries in all the TEventList in the collection in this event list
void SetDirectory(TDirectory* dir)
Remove reference to this EventList from current directory and add reference to new directory dir. dir can be 0 in which case the list does not belong to any directory.
