Member Function Documentation

int BESRegex::match	(	const char *	s,
		int	len,
		int	pos = 0
	)

Does the pattern match.

Does the regular expression match the string?

Parameters:

s	The string
len	The length of string to consider
pos	Start looking at this position in the string

Returns:

The number of characters that match, -1 if there's no match.

Definition at line 103 of file BESRegex.cc.

int BESRegex::search	(	const char *	s,
		int	len,
		int &	matchlen,
		int	pos = 0
	)

How much of the string does the pattern matche.

Does the regular expression match the string?

Parameters:

s	The string
len	The length of string to consider
matchlen	Return the length of the matched portion in this value-result parameter.
pos	Start looking at this position in the string

Returns:

The start position of the first match. This is different from POSIX regular expressions, whcih return the start position of the longest match.
