Method: Arrow::Path#valid_dirs

Defined in:
lib/arrow/path.rb

#valid_dirs ⇒ Object

Fetch the list of valid directories, using a cached value if the path has caching enabled (which is the default). Otherwise, it fetches the valid list via #find_valid_dirs and caches the result for #cache_lifespan seconds. If caching is disabled, this is equivalent to just calling #find_valid_dirs.
