Static Public Member Functions
static bool	betterThan (const HighlightToken &t1, const HighlightToken &t2)
	Whether t1 is better than t2: t1 has a non-longer prefix and a longer matching string (this makes sense only if a string was matched, and in fact this should be used only after having matched something).
Private Attributes
const unsigned int	id
	the identifier of the state
std::string	defaultElement
	the name of the element for strings when no rule matches (default: "normal") for states this should always be "normal" while for environments it should be the same element that represents the new state (e.g., "comment", "string", etc.
RuleList	ruleList
	the list of rules of this state
bool	needsReferenceReplacement
	whether one of the contained rules has dynamic references to be replaced
HighlightStatePtr	originalState
	In case this state is a copy of another state, in this field we store the original state.
Static Private Attributes
static unsigned int	global_id = 1
	the global counter to assign unique state ids

Constructor & Destructor Documentation

srchilite::HighlightState::HighlightState

(

const std::string &

e = "normal"

)

Parameters:

e

the element for strings when no rule matches (default: "normal")

srchilite::HighlightState::HighlightState

(

const HighlightState &

copy

)

Copies all the elements of the highlight state, except for the id: a new id will be used.

Parameters:

copy

Member Function Documentation

void srchilite::HighlightState::addRule

(

HighlightRulePtr

rule

)

Adss a rule to this state.

Parameters:

rule

the rule to add at the end of the list

bool srchilite::HighlightState::betterThan	(	const HighlightToken &	t1,
		const HighlightToken &	t2
	)			[static]

Whether t1 is better than t2: t1 has a non-longer prefix and a longer matching string (this makes sense only if a string was matched, and in fact this should be used only after having matched something).

Parameters:

	t1
	t2

Returns:

bool srchilite::HighlightState::findBestMatch	(	std::string::const_iterator	start,
		std::string::const_iterator	end,
		HighlightToken &	token,
		const MatchingParameters &	params
	)			const

Tries to find the rule that matches best (and first): the first rule with the smallest prefix and longest matching sequence.

Parameters:

	start	the beginning of the string for trying to match the rule
	end	the beginning of the string for trying to match the rule
	token	where results will be inserted, if the rule matched
	params	additional arguments for the matching

Returns:

whether a matching rule was found

bool srchilite::HighlightState::findBestMatch	(	const std::string &	s,
		HighlightToken &	token,
		const MatchingParameters &	params
	)			const

Tries to find the rule that matches best (and first): the first rule with the smallest prefix and longest matching sequence.

Parameters:

	s	the string for trying to match the rule
	token	where results will be inserted, if the rule matched
	params	additional arguments for the matching

Returns:

whether a matching rule was found

void srchilite::HighlightState::replaceReferences

(

const ReplacementList &

rep

)

Performs replacement of references in the rules of this state.

For each rule that needs replacement, it creates a copy of the rule.

Parameters:

the

list of values for the replacement; the first element is the value for replacing the first dynamic back reference, and so on. (it should contain 9 possibly empty elements)

HighlightRulePtr srchilite::HighlightState::replaceRule	(	RuleList::size_type	index,
		HighlightRulePtr	rule
	)

Substitutes the rule at the specified position.

The rule must exit at the specified position.

Parameters:

	index
	rule	the new rule

Returns:

the old rule
