Constructor & Destructor Documentation

CAcURL2FTS::CAcURL2FTS (  const CXMLElement &  inContentElement  )

Constructor: slurp in an url2fts file and fill the maps. Like every accessor, this accessor takes a <collection /> MRML element as input ( See also: CXMLElement for how to access the attributes of this element). Currently this accessor understands the following attributes cui-base-dir: the directory containing the following files cui-feature-file-location: the location of the "url2fts" file which translates urls to feature file names.
