12/** \class TFormLeafInfo
13This class is a small helper class to implement reading a data member
14on an object stored in a TTree.
15
16TTreeFormula now relies on a variety of TFormLeafInfo classes to handle the
17reading of the information. Here is the list of theses classes:
18 - TFormLeafInfo
19 - TFormLeafInfoDirect
20 - TFormLeafInfoNumerical
21 - TFormLeafInfoClones
22 - TFormLeafInfoCollection
23 - TFormLeafInfoPointer
24 - TFormLeafInfoMethod
25 - TFormLeafInfoMultiVarDim
26 - TFormLeafInfoMultiVarDimDirect
27 - TFormLeafInfoCast
28
29The following method are available from the TFormLeafInfo interface:
30
31 - AddOffset(Int_t offset, TStreamerElement* element)
32 - GetCounterValue(TLeaf* leaf) : return the size of the array pointed to.
33 - GetObjectAddress(TLeafElement* leaf) : Returns the location of the object pointed to.
34 - GetMultiplicity() : Returns info on the variability of the number of elements
35 - GetNdata(TLeaf* leaf) : Returns the number of elements
36 - GetNdata() : Used by GetNdata(TLeaf* leaf)
37 - GetValue(TLeaf *leaf, Int_t instance = 0) : Return the value
38 - GetValuePointer(TLeaf *leaf, Int_t instance = 0) : Returns the address of the value
39 - GetLocalValuePointer(TLeaf *leaf, Int_t instance = 0) : Returns the address of the value of 'this' LeafInfo
40 - IsString()
41 - ReadValue(char *where, Int_t instance = 0) : Internal function to interpret the location 'where'
42 - Update() : react to the possible loading of a shared library.
