This class is a small helper class to implement reading a data member on an object stored in a TTree.

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 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.
