◆ Tokenize() [1/2]

TObjArray * TString::Tokenize ( const TString & delim ) const

inherited

This function is used to isolate sequential tokens in a TString.

These tokens are separated in the string by at least one of the characters in delim. The returned array contains the tokens as TObjString's. The returned array is the owner of the objects, and must be deleted by the user.

◆ Tokenize() [2/2]

Bool_t TString::Tokenize	(	TString &	tok,
		Ssiz_t &	from,
		const char *	delim = " " ) const

inherited

Search for tokens delimited by regular expression 'delim' (default " ") in this string; search starts at 'from' and the token is returned in 'tok'.

Returns in 'from' the next position after the delimiter. Returns kTRUE if a token is found, kFALSE if not or if some inconsistency occurred. This method allows to loop over tokens in this way:

TString myl = "tok1 tok2|tok3";
TString tok;
Ssiz_t from = 0;
while (myl.Tokenize(tok, from, "[ |]")) {
   // Analyse tok
   ...
}

more convenient of the other Tokenize method when saving the tokens is not needed.

◆ ToLower()

void TString::ToLower ( )

inherited

Change string to lower-case.

Definition at line 1189 of file TString.cxx.

◆ ToUpper()

void TString::ToUpper ( )

inherited

Change string to upper case.

◆ UItoa()

TString TString::UItoa	(	UInt_t	value,
		Int_t	base )

staticinherited

Converts a UInt_t (twice the range of an Int_t) to a TString with respect to the base specified (2-36).

Thus it is an enhanced version of sprintf (adapted from versions 0.4 of http://www.jb.man.ac.uk/~slowe/cpp/itoa.html). In case of error returns the "!" string.

◆ ULLtoa()

TString TString::ULLtoa	(	ULong64_t	value,
		Int_t	base )

staticinherited

Converts a ULong64_t (twice the range of an Long64_t) to a TString with respect to the base specified (2-36).

Thus it is an enhanced version of sprintf (adapted from versions 0.4 of http://www.jb.man.ac.uk/~slowe/cpp/itoa.html). In case of error returns the "!" string.

◆ WriteString()

void TString::WriteString	(	TBuffer &	b,
		const TString *	a )

staticinherited

Write TString object to buffer.

Simplified version of TBuffer::WriteObject (does not keep track of multiple references to the same string). We need to have it here because TBuffer::ReadObject can only handle descendant of TObject
