| class | meta_entry_ |
Public Types | |
| typedef std::map< std::string, std::string >::const_iterator | iterator |
Public Member Functions | |
| void | put (const std::string &keyword, const std::string &value) |
| adds the keyword->value mapping | |
| std::string | get (const std::string &keyword) |
| retrieves the mapping for keyword (or "" if the mapping is not defined) | |
| bool | get (const std::string &keyword, std::string &value) |
| retrieves the mapping for keyword in value (and returns true if the mapping is defined or false otherwise) | |
| size_t | size () const |
| const std::string & | path () const |
| path to the file that this Casarc mirrors. | |
| iterator | begin () |
| iterator | end () |
Static Public Member Functions | |
| static Casarc & | instance () |
| return default casarc file, e.g. | |
| static void | setDefaultPath (const std::string &path) |
| set and clear the default casarc path (to something other than ~/.casarc) | |
| static void | clearDefaultPath () |
| static Casarc & | instance (const std::string &path) |
| return a casarc object attached to a particular file | |
| static const std::list< Casarc * > & | list () |
| return the list of rcfiles that have been loaded | |
Private Types | |
| enum | lock_mode { READ, READ_WRITE, WRITE, APPEND } |
Private Member Functions | |
| void | close (int) |
| int | lock (lock_mode mode) |
| returns a file descriptor or -1 on error. | |
| void | unlock (int fd) |
| void | sync () |
| double | current_modification_time (struct stat &buf) |
| void | read_file () |
| Casarc (const std::string &path) | |
| path is the path to the .casarc (or .aipsrc file) | |
| ~Casarc () | |
Static Private Member Functions | |

| std::string | filename |
| double | timestamp |
| std::map< std::string, std::string > | rcmap |
| std::map< std::string, meta_entry_ > | rcmetamap |
| this is broken off separate from the rcmap to allow the rcmap to be used for iteration by users of this class. | |
