26 // CLASS NAME : RepoStatus
29 * \short Local facts about a repository
30 * This class represents the status of a
31 * repository on the system.
33 * Anything that is not provided on the metadata
34 * files, like the timestamp of the downloaded
35 * metadata, and its checksum.
39 friend std::ostream & operator<<( std::ostream & str, const RepoStatus & obj );
44 * reads the status from a file which contains the
45 * checksum and timestamp in each line.
47 * \throws Exception If the file is not valid or accessible
49 static RepoStatus fromCookieFile( const Pathname &path );
52 * save the status information to a cookie file
53 * \throws Exception if the file can't be saved
55 void saveToCookieFile( const Pathname &path ) const;
58 * Checksum of the repository.
59 * Usually the checksum of the index, but any
60 * checksum that changes when the repository changes
61 * in any way is sufficient.
63 std::string checksum() const;
66 * timestamp of the repository. If the repository
67 * changes, it has to be updated as well with the
70 Date timestamp() const;
73 * \short Is the status empty?
75 * An empty status means that the status
81 * set the repository checksum \see checksum
84 RepoStatus & setChecksum( const std::string &checksum );
87 * set the repository timestamp \see timestamp
90 RepoStatus & setTimestamp( const Date ×tamp );
100 * \short Status from a single file
101 * As most repository state is represented
102 * by the status of the index file, you can
103 * construct the status from a file.
105 * \note construct from a non existing
106 * file will result in an empty status
