Detailed Description

This is a simple wrapper of PCRE library.

It is designed to be used with sub_match, match_results, regex_match and regex_search template functions.

It provides API similar to ones of Boost.Regex but it is also much simplified.

Constructor & Destructor Documentation

booster::regex::regex

(

regex const &

)

Copy regular expression. Note. This is much more efficient then creating a new expression with same patter.

booster::regex::regex	(	std::string const &	pattern,
		int	flags = normal
	)

Create regular expression using a patter and special flags. Note, at this point flags should be normal or perl only (which are equivalent). May be extended in future.

Throws regex_error in case of invalid expression.

Member Function Documentation

void booster::regex::assign	(	std::string const &	pattern,
		int	flags = normal
	)

Assigns regular expression using a patter and special flags. Note, at this point flags should be normal or perl only (which are equivalent). May be extended in future.

Throws regex_error in case of invalid expression.

bool booster::regex::empty

(

)

const

Returns true if the expression wasn't assigned.

int booster::regex::flags

(

)

const

Get expression flags. Now always 0.

unsigned booster::regex::mark_count

(

)

const

Get number of captured subexpressions.

bool booster::regex::match	(	char const *	begin,
		char const *	end,
		int	flags = 0
	)		const

Match the expression in the text in range [begin,end) exactly. Parameter flags currently unused.

Return true if matches

bool booster::regex::match	(	char const *	begin,
		char const *	end,
		std::vector< std::pair< int, int > > &	marks,
		int	flags = 0
	)		const

Match the expression in the text in range [begin,end) exactly. Parameter flags currently unused.

Return true if matches, and stores captured sub-patterns in marks. Each pair represents a text in rage [begin+first,begin+second).

If no such patter was captured, returns (-1,-1) as pair.

regex const& booster::regex::operator=

(

regex const &

)

Copy regular expression. Note. This is much more efficient then creating a new expression with same patter.

bool booster::regex::search	(	char const *	begin,
		char const *	end,
		int	flags = 0
	)		const

Search the expression in the text in range [begin,end). Parameter flags currently unused.

Return true if found.

bool booster::regex::search	(	char const *	begin,
		char const *	end,
		std::vector< std::pair< int, int > > &	marks,
		int	flags = 0
	)		const

Search the expression in the text in range [begin,end). Parameter flags currently unused.

Return true if found, and stores captured sub-patterns in marks. Each pair represents a text in rage [begin+first,begin+second).

If no such patter was captured, returns (-1,-1) as pair.

std::string booster::regex::str

(

)

const

Get the string that the regular expression was created with.
