Constructor & Destructor Documentation

RegEx::RegEx (  const char *  regex, int  options = 0 )

The constructor's first parameter is the regular expression the created object shall implement. Optional parameter options can be any combination of PCRE options accepted by pcre_compile(). If compiling the regular expression fails, an error message string is thrown as an exception. Parameters: regex  Adierazpen erregularraren katea. options  Aukera gehigarriak.

Member Function Documentation

const char * RegEx::Match (  int  i  )

Method Match() returns a pointer to the matched substring specified with parameter i. Match() may only be called after a successful call to Search() or SearchAgain() and applies to that last Search()/SearchAgain() call. Parameter i must be less than SubStrings(). Match(-1) returns the last searched subject. Match(0) returns the match of the complete regular expression. Match(1) returns $1, etc. Parameters: i  Zenbatgarren katea nahi dugun. Returns: i. katea.

bool RegEx::Search (  const char *  subject, int  len = -1, int  options = 0 )

Method Search() applies the regular expression to parameter subject. Optional parameter len can be used to pass the subject's length to Search(). If not specified (or less than 0), strlen() is used internally to determine the length. Parameter options can contain any combination of options PCRE_ANCHORED, PCRE_NOTBOL, PCRE_NOTEOL, PCRE_NOTEMPTY. Search() returns true if a match is found. Parameters: subject  Adierazpen erregularra aplikatuko diogun katea. len  Katearen luzera (hautazkoa). options  Aukera gehigarriak. Returns: True adierazpena betetzen bada, false bestela.

bool RegEx::SearchAgain (  int  options = 0  )

SearchAgain() again applies the regular expression to parameter subject last passed to a successful call of Search(). It returns true if a further match is found. Subsequent calls to SearchAgain() will find all matches in subject. Example: if (Pattern.Search(astring)) { do { printf("%s\n", Pattern.Match()); } while (Pattern.SearchAgain()); } Parameter options is interpreted as for method Search(). Parameters: options  Aukera gehigarriak. Returns: True adierazpena betetzen bada, false bestela.

int RegEx::SubStrings (  void   )  const [inline]

Method SubStrings() returns the number of substrings defined by the regular expression. The match of the entire expression is also considered a substring, so the return value will always be >= 1. Returns: Adierazpen erregularrak harrapatutako kate kopurua.
