Constructor & Destructor Documentation

EntryCache()

echomap::FilesystemCombo::EntryCache::EntryCache ( const std::filesystem::path & directory )

explicit

Creates a new EntryCache and populates it for the given root directory.

Upon constructing the EntryCache, the (immediate) children of the given directory are packed into Entry objects and collated into the cache. Exceptions may be thrown from the std::filesystem API. Symbolic links are followed.

Parameters

directory

The path of the directory root to be traversed.
