typedef wchar_t reflex::unicode_t

Function Documentation

template<typename S1 , typename S2 >

bool reflex::is_disjoint	(	const S1 &	s1,
		const S2 &	s2
	)

Check if sets s1 and s2 are disjoint.

Returns

true or false

template<typename T , typename S >

bool reflex::is_in_set ( const T &  x, const S &  s  )

inline

Check if value x is in set s.

Returns

true or false

template<typename S1 , typename S2 >

bool reflex::is_subset	(	const S1 &	s1,
		const S2 &	s2
	)

Check if set s1 is a subset of set s2.

Returns

true or false

int reflex::isword ( int  c )

inline

Check word character.

Returns

nonzero if argument c is in [A-Za-z0-9_], zero otherwise.

Parameters

c	Character to check

template<typename S1 , typename S2 >

void reflex::set_delete	(	S1 &	s1,
		const S2 &	s2
	)

Delete elements of set s2 from set s1.

template<typename S1 , typename S2 >

void reflex::set_insert ( S1 &  s1, const S2 &  s2  )

inline

std::string reflex::utf8	(	unicode_t	a,
		unicode_t	b,
		bool	strict = true,
		const char *	esc = NULL
	)

Convert a UCS range [a,b] to a UTF-8 regex pattern.

Returns

regex string to match the UCS range encoded in UTF-8.

Parameters

a	lower bound of UCS range
b	upper bound of UCS range
strict	returned regex is strict UTF-8 (true) or lean UTF-8 (false)
esc	escape char(s), 0-3 chars limit, one backslash "\\" is the default
