updateSource()

void CuFormulaParser::updateSource	(	size_t	i,
		const std::string &	s
	)

Parameters

i	the index of the source to be updated
s	the new name

This can be used to update sources after wildcards ("$1, $2) have been replaced by engine specific readers.

Example

CuFormulaReader calls updateSource after QuWatcher::setSource so that CuFormulaParser contains the complete source name, after wildcards have been replaced by QuWatcher.
