Using a WCMatcher is the preferred - method for scanning strings. WCMatchers are not thread-safe. WCMatchers require - very little dynamic memory, hence one is encouraged to create several - instances of a matcher when necessary as opposed to sharing a single instance - of a matcher. -

- The most common methods needed by the matcher are matches, - findNextMatch, and getGroup. matches - and findNextMatch both return success or failure, and further - details can be gathered from their documentation. -

- Unlike Java's WCMatcher, this class allows you to change the string - you are matching against. This provides a small optimization, since you no - longer need multiple matchers for a single pattern in a single thread. -

- This class also provides an extremely handy method for replacing text with - captured data via the replaceWithGroups method. A typical - invocation looks like: - 

-  wchar_t buf[10000];
-  CMStringW str = "\\5 (user name \\1) uses \\7 for his/her shell and \\6 is their home directory";
-  FILE * fp = fopen("/etc/passwd", "r");
-  WCPattern::registerWCPattern("entry", "[^:]+");
-  WCPattern * p = WCPattern::compile("^({entry}):({entry}):({entry}):({entry}):({entry}):({entry}):({entry})$",
-                                 WCPattern::MULTILINE_MATCHING | WCPattern::UNIX_LINE_MODE);
-  WCMatcher * m = p->createWCMatcher("");
-  while (fgets(buf, 9999, fp))
-  {
-    m->setString(buf);
-    if (m->matches())
-    {
-      printf("%s\n", m->replaceWithGroups(str).c_str());
-    }
-  }
-  fclose(fp);

- Calling any of the following functions before first calling - matches, findFirstMatch, or - findNextMatch results in undefined behavior and may cause your - program to crash. - - - -

- The function findFirstMatch will attempt to find the first match - in the input string. The same results can be obtained by first calling - reset followed by findNextMatch. -

- To eliminate the necessity of looping through a string to find all the - matching substrings, findAll was created. The function will find - all matching substrings and return them in a vector. If you need - to examine specific capture groups within the substrings, then this method - should not be used. - - @author Jeffery Stuart - @since March 2003, Stable Since November 2004 - @version 1.05.00 - @memo Mutable object used on instances of a WCPattern class - */ -class WCMatcher -{ - friend class NFAUNode; - friend class NFAStartUNode; - friend class NFAEndUNode; - friend class NFAGroupHeadUNode; - friend class NFAGroupLoopUNode; - friend class NFAGroupLoopPrologueUNode; - friend class NFAGroupTailUNode; - friend class NFALookBehindUNode; - friend class NFAStartOfLineUNode; - friend class NFAEndOfLineUNode; - friend class NFAEndOfMatchUNode; - friend class NFAReferenceUNode; - friend class WCPattern; - private: - /** - Creates a new matcher object against text using - pattern. - - @param pattern The pattern with which to search - @param text The text in which to search - */ - WCMatcher(WCPattern *pattern, const CMStringW & ext); - protected: - /// The pattern we use to match - WCPattern *pat; - /// The string in which we are matching - const CMStringW *str; - /// The starting point of our match - int start; - /// An array of the starting positions for each group - int *starts; - /// An array of the ending positions for each group - int *ends; - /// An array of private data used by NFAUNodes during matching - int *groups; - /// An array of private data used by NFAUNodes during matching - int *groupIndeces; - /// An array of private data used by NFAUNodes during matching - int *groupPos; - /// The ending index of the last match - int lm; - /// The number of capturing groups we have - int gc; - /// The number of non-capturing groups we havew - int ncgc; - /// Whether or not we have matched something (used only by findFirstMatch and findNextMatch) - int matchedSomething; - /// The flags with which we were made - unsigned long flags; - /// Called by reset to clear the group arrays - void clearGroups(); - public: - /// Used internally by match to signify we want the entire string matched - const static int MATCH_ENTIRE_STRING; - public: - /// Cleans up the dynamic memory used by this matcher - ~WCMatcher(); - /** - Replaces the contents of str with the appropriate captured - text. str should have at least one back reference, otherwise - this function does nothing. - @param str The string in which to replace text - @return A string with all backreferences appropriately replaced - */ - CMStringW replaceWithGroups(const CMStringW & str); - /** - The flags currently being used by the matcher. - @return Zero - */ - unsigned long getFlags() const; - /** - The text being searched by the matcher. - @return the text being searched by the matcher. - */ - const CMStringW& getText() const; - - /** - Scans the string from start to finish for a match.
