IsNumberConstant()

bool IsNumberConstant

(

const std::string &

str

)

Helper function checking if a string contains a literal number.

Whitespaces are not allowed as part of a valid number-string

Returns

true if it can be converted to a valid number (floating or integer), false otherwise.

Definition at line 118 of file TTreeFormula.cxx.

R__LoadBranch()

static Int_t R__LoadBranch ( TBranch * br, Long64_t entry, bool quickLoad )

inlinestatic

The function returns the number of bytes read from the input buffer.

If entry does not exist or (entry!=readEntry && quickload), the function returns 0. If an I/O error occurs, the function returns -1.
