 Regular expression class.                                            
                                                                      


TRegexp(const char *re, Bool_t wildcard)
 Create a regular expression from the input string. If wildcard is true
 then the input string contains a wildcard expression (see MakeWildcard()).

TRegexp(const TString& re)
 Create a regular expression from a TString.

TRegexp(const TRegexp& r)
 Copy ctor.

~TRegexp()

void GenPattern(const char *str)
 Generate the regular expression pattern.

void CopyPattern(const TRegexp& r)
 Copy the regular expression pattern.

const char* MakeWildcard(const char *re)
 This routine transforms a wildcarding regular expression into
 a general regular expression used for pattern matching.
 When using wildcards the regular expression is assumed to be
 preceded by a "^" (BOL) and terminated by a "$" (EOL). Also, all
 "*"'s (closures) are assumed to be preceded by a "." (any character)
 and all .'s are escaped (so *.ps is different from *.eps).

Ssiz_t Index(const TString& string, Ssiz_t* len, Ssiz_t i) const
 Find the first occurance of the regexp in string and return the position.
 Len is length of the matched string and i is the offset at which the
 matching should start.
