Constructor & Destructor Documentation

CRegExp() [1/3]

CRegExp::CRegExp	(	bool	caseless = false,
		CRegExp::utf8Mode	utf8 = asciiOnly )

Parameters

caseless	(optional) Matching will be case insensitive if set to true or case sensitive if set to false
utf8	(optional) Control UTF-8 processing

CRegExp() [2/3]

CRegExp::CRegExp	(	bool	caseless,
		CRegExp::utf8Mode	utf8,
		const char *	re,
		studyMode	study = NoStudy )

Create new CRegExp object and compile regexp expression in one step

Warning

Use only with hardcoded regexp when you're sure that regexp is compiled without errors

Parameters

caseless	Matching will be case insensitive if set to true or case sensitive if set to false
utf8	Control UTF-8 processing
re	The regular expression
study	(optional) Controls study of expression, useful if expression will be used several times
