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.

4063/// \brief Evaluate this treeformula
4064/// \tparam T The type used to interpret the numbers then used for the operations
4065/// \param instance iteration instance
4066/// \param stringStackArg formula as string
4067/// \return the result of the evaluation, or a signaling NaN if out of bounds
4068///
4069/// \warning Care has to be taken before calling this function with std::vector
4070/// or dynamically sized objects, rather than plain fixed-size arrays.
4071/// For example, this works without problems:
4072/// ~~~{.cpp}
4073/// TTree t("t", "t");
4074/// Float_t x[2]{};
4075/// t.Branch("xa", &x, "x[2]/F");
4076/// x[1] = 1;
4077/// t.Fill();
4078/// x[1] = 2;
4079/// t.Fill();
4080/// t.Scan();
4081/// TTreeFormula tfx("tfx", "xa[1]", &t);
4082/// t.GetEntry(0);
4083/// tfx.EvalInstance()
4084/// t.GetEntry(1);
4085/// tfx.EvalInstance()
4086/// ~~~
4087/// But the following fails (independently on whether the size changed or not between entries):
4088/// ~~~{.cpp}
4089/// TTree t("t", "t");
4090/// vector<Short_t> v;
4091/// t.Branch("vec", &v);
4092/// v.push_back(2);
4093/// v.push_back(3);
4094/// t.Fill();
4095/// v.clear();
4096/// v.push_back(4);
4097/// v.push_back(5);
4098/// t.Fill();
4099/// t.Scan();
4100/// TTreeFormula tfv1("tfv1", "vec[1]", &t);
4101/// TTreeFormula tfv("tfv", "vec", &t);
4102/// t.GetEntry(0);
4103/// tfv1.EvalInstance()
4104/// tfv.EvalInstance(1)
4105/// t.GetEntry(1);
4106/// tfv1.EvalInstance()
4107/// tfv.EvalInstance(1)
4108/// ~~~
4109/// To prevent this, when working with objects with dynamic size for each entry, one needs
4110/// to mimick what TTree::Scan does, i.e. to check the value of
4111/// `GetNdata()` before calling `EvalInstance()`:
4112/// ~~~{.cpp}
4113/// t.GetEntry(0);
4114/// if (tfv1.GetNdata() > 0)
4115/// tfv1.EvalInstance()
4116/// if (tfv.GetNdata() > 1)
4117/// tfv.EvalInstance(1)
4118/// t.GetEntry(1);
4119/// if (tfv1.GetNdata() > 0)
4120/// tfv1.EvalInstance()
4121/// if (tfv.GetNdata() > 1)
4122/// tfv.EvalInstance(1)
4123/// ~~~
4124/// Note that for `tfv1`, even if the index is fixed in the formula and even if each entry
4125/// had the same std::vector size, since the formula contains a branch with theoretically variable size,
4126/// one must check GetNData() as there might 0 or 1 answers. Since even with fixed index,
4127/// the collection might be too small to fulfill it.
4128/// TTreeFormula::GetMultiplicity tells you (indirectly) whether you need to call GetNData or not for a given formula.
