Detailed Description

Function Documentation

areActiveStatesEmpty()

bool teditor::parser::NFA::areActiveStatesEmpty ( ) const

inline

Tells if after the current step() whether there are any active states still remaining. So, this can be used to prematurely stop the regex search in the string.

Returns

true if there are no more actives states, else false

getMatchPos()

const Point& teditor::parser::NFA::getMatchPos ( ) const

inline

After the search has finished, use this to know the latest position of the match of the regex in the input string.

Returns

if match found, its latest position in string, else NFA::NoMatch

isMatch()

bool teditor::parser::NFA::isMatch

(

bool

lastStateRemaining = false

)

const

checks if we have reached match state, indicating a regex match

Parameters

lastStateRemaining

if set to true, means that this will expect only one state to be remaining which should be Match state.

Returns

true if match has been found, else false

reset()

void teditor::parser::NFA::reset

(

)

Reset all the variables used during regex search. This needs to be called once before beginning of every search.

step()

bool teditor::parser::NFA::step	(	char	c,
		const Point &	pos
	)

Step through the NFA state using the current char.

Parameters

c	current char
pos	its position in the input string

Returns

true if input was consumed by any of the active states, else false
