concatenateStrings()

void NumeRe::StringLogicParser::concatenateStrings ( std::string &  sExpr )

protected

This member function performs the actual string concatenation of the passed string expression.

Parameters

sExpr

string&

Returns

void

This member is called by StringParser::applyElementaryStringOperations() for the concatenation.

detectPathTokens()

size_t NumeRe::StringLogicParser::detectPathTokens ( const std::string &  sString, size_t  nPos  )

private

This member function is a helper for StringLogicParser::detectStringLogicals().

Parameters

sString	const string&
nPos	size_t

Returns

size_t

This function will identify path tokens, which will start at the passed position.

getStringTernaryExpression()

vector< string > NumeRe::StringLogicParser::getStringTernaryExpression ( std::string &  sLine, size_t &  nPos  )

private

This member function is a helper for StringLogicParser::evalStringLogic().

Parameters

sLine	string&
nPos	size_t&

Returns

vector<string>

It will return the expression parts of the current ternary at nPos in the components of the returned vector. nPos ist the position of the question mark.
