		Bool_t	zapOnError = kFALSE
	)

Read the next token and return kTRUE if it is identical to the given 'expected' token.

Definition at line 398 of file RooStreamParser.cxx.

getPunctuation()

TString RooStreamParser::getPunctuation ( ) const

inline

Definition at line 32 of file RooStreamParser.h.

isPunctChar()

Bool_t RooStreamParser::isPunctChar

(

char

c

)

const

Check if given char is considered punctuation.

Definition at line 110 of file RooStreamParser.cxx.

		Bool_t	zapOnError = kFALSE
	)

Read the next token and convert it to a Double_t.

Returns true if an error occurred in reading or conversion

Definition at line 417 of file RooStreamParser.cxx.

readInteger()

Bool_t RooStreamParser::readInteger	(	Int_t &	value,
		Bool_t	zapOnError = kFALSE
	)

Read a token and convert it to an Int_t.

Returns true if an error occurred in reading or conversion

Definition at line 457 of file RooStreamParser.cxx.

readLine()

TString RooStreamParser::readLine

(

)

Read an entire line from the stream and return as TString This method recognizes the use of '\' in the istream as line continuation token.

Definition at line 310 of file RooStreamParser.cxx.

readString()

Bool_t RooStreamParser::readString	(	TString &	value,
		Bool_t	zapOnError = kFALSE
	)

Read a string token.

Returns true if an error occurred in reading or conversion. If a the read token is enclosed in quotation marks those are stripped in the returned value

Definition at line 491 of file RooStreamParser.cxx.

readToken()

TString RooStreamParser::readToken

(

)

Read one token separated by any of the know punctuation characters This function recognizes and handles comment lines in the istream (those starting with '#', quoted strings ("") the content of which is not tokenized and '+-.

' characters that are part of a floating point numbers and are exempt from being interpreted as a token separator in case '+-.' are defined as token separators.

Definition at line 130 of file RooStreamParser.cxx.

setPunctuation()

void RooStreamParser::setPunctuation

(

const TString &

punct

)

Definition at line 100 of file RooStreamParser.cxx.

zapToEnd()

void RooStreamParser::zapToEnd

(

Bool_t

inclContLines = kFALSE

)

Eat all characters up to and including then end of the current line.

If inclContLines is kTRUE, all continuation lines marked by the '\' token are zapped as well
