Bool_t isPunctChar(char c) const
Check if given char is considered punctuation.
Bool_t atEOL()
If true, parser is at end of line in stream.
Bool_t readInteger(Int_t &value, Bool_t zapOnError=kFALSE)
Read a token and convert it to an Int_t.
Bool_t readDouble(Double_t &value, Bool_t zapOnError=kFALSE)
Read the next token and convert it to a Double_t.
Bool_t convertToDouble(const TString &token, Double_t &value)
Convert given string to a double. Return true if the conversion fails.
Bool_t readString(TString &value, Bool_t zapOnError=kFALSE)
Read a string token.
void setPunctuation(const TString &punct)
Change list of characters interpreted as punctuation.
void zapToEnd(Bool_t inclContLines=kFALSE)
Eat all characters up to and including then end of the current line.
Bool_t expectToken(const TString &expected, Bool_t zapOnError=kFALSE)
Read the next token and return kTRUE if it is identical to the given 'expected' token.
virtual ~RooStreamParser()
Destructor.
std::istream * _is

TString getPunctuation() const
Bool_t convertToString(const TString &token, TString &string)
Convert given token to a string (i.e. remove eventual quotation marks)
RooStreamParser(std::istream &is)
