Constructor & Destructor Documentation

srchilite::RegexHighlightRule::RegexHighlightRule ( const std::string &  s)
Parameters
sthe string representing the regular expression
srchilite::RegexHighlightRule::RegexHighlightRule ( const std::string &  name,
const std::string &  s 
)
Parameters
namethe element name represented by this rule
sthe string representing the regular expression

Member Function Documentation

void srchilite::HighlightRule::addElem ( const std::string &  name)
inherited

Adds an element name to the list of this rule.

Parameters
namethe name to add
HighlightRule * srchilite::RegexHighlightRule::clone ( )
virtual
Returns
a copy of this rule.

Implements srchilite::HighlightRule.

void srchilite::RegexHighlightRule::replaceReferences ( const ReplacementList rep)
virtual

Performs replacement of references in this rule.

Parameters
thelist 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)

Implements srchilite::HighlightRule.

bool srchilite::RegexHighlightRule::tryToMatch ( std::string::const_iterator  start,
std::string::const_iterator  end,
HighlightToken token,
const MatchingParameters params 
)
virtual

Try to match this rule against the passed string.

Parameters
startthe beginning of the string for trying to match the rule
endthe beginning of the string for trying to match the rule
tokenwhere results will be inserted, if the rule matched
paramsadditional arguments for the matching
Returns
the result of this matching

Implements srchilite::HighlightRule.

bool srchilite::HighlightRule::tryToMatch ( const std::string &  s,
HighlightToken token,
const MatchingParameters params 
)
virtualinherited

Try to match this rule against the passed string (implemented by calling the pure virtual function tryToMatch below).

The passed token is assumed to be reset (i.e., no existing matching information is stored in it when passing it to this method).

Parameters
sthe string for trying to match the rule
tokenwhere results will be inserted, if the rule matched
paramsadditional arguments for the matching
Returns
the result of this matching
