TTreeFormula Class Reference

Used to pass a selection expression to the Tree drawing routine.

See TTree::Draw

A TreeFormula can contain any arithmetic expression including standard operators and mathematical functions separated by operators. Examples of valid expression:

"x<y && sqrt(z)>3.2"

TTreeFormula now relies on a variety of TFormLeafInfo classes to handle the reading of the information. Here is the list of theses classes:

The following method are available from the TFormLeafInfo interface:

  • AddOffset(Int_t offset, TStreamerElement* element)
  • GetCounterValue(TLeaf* leaf) : return the size of the array pointed to.
  • GetObjectAddress(TLeafElement* leaf) : Returns the the location of the object pointed to.
  • GetMultiplicity() : Returns info on the variability of the number of elements
  • GetNdata(TLeaf* leaf) : Returns the number of elements
  • GetNdata() : Used by GetNdata(TLeaf* leaf)
  • GetValue(TLeaf *leaf, Int_t instance = 0) : Return the value
  • GetValuePointer(TLeaf *leaf, Int_t instance = 0) : Returns the address of the value
  • GetLocalValuePointer(TLeaf *leaf, Int_t instance = 0) : Returns the address of the value of 'this' LeafInfo
  • IsString()
  • ReadValue(char *where, Int_t instance = 0) : Internal function to interpret the location 'where'
  • Update() : react to the possible loading of a shared library.

virtual

Check if name is in the list of Tree/Branch leaves.

This member function redefines the function in ROOT::v5::TFormula If a leaf has a name corresponding to the argument name, then returns a new code.

A TTreeFormula may contain more than one variable. For each variable referenced, the pointers to the corresponding branch and leaf is stored in the object arrays fBranches and fLeaves.

name can be :

  • Leaf_Name (simple variable or data member of a ClonesArray)
  • Branch_Name.Leaf_Name
  • Branch_Name.Method_Name
  • Leaf_Name[index]
  • Branch_Name.Leaf_Name[index]
  • Branch_Name.Leaf_Name[index1]
  • Branch_Name.Leaf_Name[][index2]
  • Branch_Name.Leaf_Name[index1][index2]

New additions:

  • Branch_Name.Leaf_Name[OtherLeaf_Name]
  • Branch_Name.Datamember_Name
  • '.' can be replaced by '->'

    and

  • Branch_Name[index1].Leaf_Name[index2]
  • Leaf_name[index].Action().OtherAction(param)
  • Leaf_name[index].Action()[val].OtherAction(param)

The expected returns values are

  • -2 : the name has been recognized but won't be usable
  • -1 : the name has not been recognized
  • >=0 : the name has been recognized, return the internal code for this name.
