Protected Methods

Method	Description
Capture ( int capnum, int start, int end ) : void	Called by Go() to capture a subexpression. Note that the capnum used here has already been mapped to a non-sparse index (by the code generator RegexWriter).
CharInClass ( char ch, string charClass ) : bool
CharInSet ( char ch, string set, string category ) : bool
CheckTimeout ( ) : void
Crawl ( int i ) : void	Save a number on the longjump unrolling stack
Crawlpos ( ) : int	Get the height of the stack
DoubleCrawl ( ) : void	Increases the size of the longjump unrolling stack.
DoubleStack ( ) : void	Called by the implementation of Go() to increase the size of the grouping stack.
DoubleTrack ( ) : void	Called by the implementation of Go() to increase the size of the backtracking stack.
EnsureStorage ( ) : void	Called by the implementation of Go() to increase the size of storage
FindFirstChar ( ) : bool	The responsibility of FindFirstChar() is to advance runtextpos until it is at the next position which is a candidate for the beginning of a successful match.
Go ( ) : void	The responsibility of Go() is to run the regular expression at runtextpos and call Capture() on all the captured subexpressions, then to leave runtextpos at the ending position. It should leave runtextpos where it started if there was no match.
InitTrackCount ( ) : void	InitTrackCount must initialize the runtrackcount field; this is used to know how large the initial runtrack and runstack arrays must be.
IsBoundary ( int index, int startpos, int endpos ) : bool	Called by the implementation of Go() to decide whether the pos at the specified index is a boundary or not. It's just not worth emitting inline code for this logic.
IsECMABoundary ( int index, int startpos, int endpos ) : bool
IsMatched ( int cap ) : bool	Call out to runmatch to get around visibility issues
MatchIndex ( int cap ) : int	Call out to runmatch to get around visibility issues
MatchLength ( int cap ) : int	Call out to runmatch to get around visibility issues
Popcrawl ( ) : int	Remove a number from the longjump unrolling stack
RegexRunner ( ) : System
Scan ( Regex regex, string text, int textbeg, int textend, int textstart, int prevlen, bool quick ) : Match	Scans the string to find the first match. Uses the Match object both to feed text in and as a place to store matches that come out. All the action is in the abstract Go() method defined by subclasses. Our responsibility is to load up the class members (as done here) before calling Go. The optimizer can compute a set of candidate starting characters, and we could use a separate method Skip() that will quickly scan past any characters that we know can't match.
Scan ( Regex regex, string text, int textbeg, int textend, int textstart, int prevlen, bool quick, System.TimeSpan timeout ) : Match
TransferCapture ( int capnum, int uncapnum, int start, int end ) : void	Called by Go() to capture a subexpression. Note that the capnum used here has already been mapped to a non-sparse index (by the code generator RegexWriter).
