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 * \returns An empty \ref RepoStatus if the file does not
48 * exist or is not readable.
50 static RepoStatus fromCookieFile( const Pathname &path );
53 * save the status information to a cookie file
54 * \throws Exception if the file can't be saved
56 void saveToCookieFile( const Pathname &path ) const;
59 * Checksum of the repository.
60 * Usually the checksum of the index, but any
61 * checksum that changes when the repository changes
62 * in any way is sufficient.
64 std::string checksum() const;
67 * timestamp of the repository. If the repository
68 * changes, it has to be updated as well with the
71 Date timestamp() const;
74 * \short Is the status empty?
76 * An empty status means that the status
82 * set the repository checksum \see checksum
85 RepoStatus & setChecksum( const std::string &checksum );
88 * set the repository timestamp \see timestamp
91 RepoStatus & setTimestamp( const Date ×tamp );
101 * \short Status from a single file
102 * As most repository state is represented
103 * by the status of the index file, you can
104 * construct the status from a file.
106 * \note construct from a non existing
107 * file will result in an empty status
