AddFile()

virtual bool FileScanner::AddFile ( const std::string &  filename, size_t  basepath_length, const std::string &  tar_filename  )

pure virtual

Add a file with the given filename.

Parameters

filename	the full path to the file to read
basepath_length	amount of characters to chop of before to get a filename relative to the search path.
tar_filename	the name of the tar file the file is read from.

Returns

true if the file is added.

Implemented in SocialIntegrationFileScanner, BaseMedia< Tbase_set >, BaseMedia< GraphicsSet >, BaseMedia< MusicSet >, BaseMedia< SoundsSet >, FiosFileScanner, GRFFileScanner, ScriptScanner, TarScanner, ScenarioScanner, LanguageScanner, and ScriptFileChecksumCreator.
