clearOdCache()

OdCacheClearResult clearOdCache

(

const std::filesystem::path &

data_dir

)

Deletes every object dictionary cache file in the data directory.

Only files with the layout of odCacheFilePath() are deleted. Other files in the data directory are not touched. A vendor or product folder that is empty afterwards is deleted as well.

Parameters

data_dir

The data directory, see –data-dir. A directory that does not exist holds no cache, and the result is empty.

Returns

The deleted files and the files that could not be deleted.
