58/** \class TTreeFormula
59Used to pass a selection expression to the Tree drawing routine. See TTree::Draw
60
61A TreeFormula can contain any arithmetic expression including
62standard operators and mathematical functions separated by operators.
63Examples of valid expression:
64~~~{.cpp}
65 "x<y && sqrt(z)>3.2"
66~~~
67TTreeFormula now relies on a variety of TFormLeafInfo classes to handle the
68reading of the information. Here is the list of theses classes:
69 - TFormLeafInfo
70 - TFormLeafInfoDirect
71 - TFormLeafInfoNumerical
72 - TFormLeafInfoClones
73 - TFormLeafInfoCollection
74 - TFormLeafInfoPointer
75 - TFormLeafInfoMethod
76 - TFormLeafInfoMultiVarDim
77 - TFormLeafInfoMultiVarDimDirect
78 - TFormLeafInfoCast
79
80The following method are available from the TFormLeafInfo interface:
81
82 - AddOffset(Int_t offset, TStreamerElement* element)
83 - GetCounterValue(TLeaf* leaf) : return the size of the array pointed to.
84 - GetObjectAddress(TLeafElement* leaf) : Returns the location of the object pointed to.
85 - GetMultiplicity() : Returns info on the variability of the number of elements
86 - GetNdata(TLeaf* leaf) : Returns the number of elements
87 - GetNdata() : Used by GetNdata(TLeaf* leaf)
88 - GetValue(TLeaf *leaf, Int_t instance = 0) : Return the value
89 - GetValuePointer(TLeaf *leaf, Int_t instance = 0) : Returns the address of the value
90 - GetLocalValuePointer(TLeaf *leaf, Int_t instance = 0) : Returns the address of the value of 'this' LeafInfo
91 - IsString()
92 - ReadValue(char *where, Int_t instance = 0) : Internal function to interpret the location 'where'
93 - Update() : react to the possible loading of a shared library.

4062/// \brief Evaluate this treeformula
4063/// \tparam T The type used to interpret the numbers then used for the operations
4064/// \param instance iteration instance
4065/// \param stringStackArg formula as string
4066/// \return the result of the evaluation, or a signaling NaN if out of bounds
4067///
4068/// \warning Care has to be taken before calling this function with std::vector
4069/// or dynamically sized objects, rather than plain fixed-size arrays.
4070/// For example, this works without problems:
4071/// ~~~{.cpp}
4072/// TTree t("t", "t");
4073/// Float_t x[2]{};
4074/// t.Branch("xa", &x, "x[2]/F");
4075/// x[1] = 1;
4076/// t.Fill();
4077/// x[1] = 2;
4078/// t.Fill();
4079/// t.Scan();
4080/// TTreeFormula tfx("tfx", "xa[1]", &t);
4081/// t.GetEntry(0);
4082/// tfx.EvalInstance()
4083/// t.GetEntry(1);
4084/// tfx.EvalInstance()
4085/// ~~~
4086/// But the following fails (independently on whether the size changed or not between entries):
4087/// ~~~{.cpp}
4088/// TTree t("t", "t");
4089/// vector<Short_t> v;
4090/// t.Branch("vec", &v);
4091/// v.push_back(2);
4092/// v.push_back(3);
4093/// t.Fill();
4094/// v.clear();
4095/// v.push_back(4);
4096/// v.push_back(5);
4097/// t.Fill();
4098/// t.Scan();
4099/// TTreeFormula tfv1("tfv1", "vec[1]", &t);
4100/// TTreeFormula tfv("tfv", "vec", &t);
4101/// t.GetEntry(0);
4102/// tfv1.EvalInstance()
4103/// tfv.EvalInstance(1)
4104/// t.GetEntry(1);
4105/// tfv1.EvalInstance()
4106/// tfv.EvalInstance(1)
4107/// ~~~
4108/// To prevent this, when working with objects with dynamic size for each entry, one needs
4109/// to mimick what TTree::Scan does, i.e. to check the value of
4110/// `GetNdata()` before calling `EvalInstance()`:
4111/// ~~~{.cpp}
4112/// t.GetEntry(0);
4113/// if (tfv1.GetNdata() > 0)
4114/// tfv1.EvalInstance()
4115/// if (tfv.GetNdata() > 1)
4116/// tfv.EvalInstance(1)
4117/// t.GetEntry(1);
4118/// if (tfv1.GetNdata() > 0)
4119/// tfv1.EvalInstance()
4120/// if (tfv.GetNdata() > 1)
4121/// tfv.EvalInstance(1)
4122/// ~~~
4123/// Note that for `tfv1`, even if the index is fixed in the formula and even if each entry
4124/// had the same std::vector size, since the formula contains a branch with theoretically variable size,
4125/// one must check GetNData() as there might 0 or 1 answers. Since even with fixed index,
4126/// the collection might be too small to fulfill it.
4127/// TTreeFormula::GetMultiplicity tells you (indirectly) whether you need to call GetNData or not for a given formula.
