Detailed Description

template<class CatalogT = catalog::Catalog, class HistoryT = history::SqliteHistory, class ReflogT = manifest::Reflog>
class LocalObjectFetcher< CatalogT, HistoryT, ReflogT >

This is an AbstractObjectFetcher<> accessing locally stored repository files. Note that this implementation does not take care of any repository signature verification.
