|
| |
=head1 SYNOPSIS |
| |
|
| |
This file is an interface to the lonc processes of |
| |
the LON-CAPA network as well as set of elaborated functions for handling information |
| |
necessary for navigating through a given cluster of LON-CAPA machines within a |
| |
domain. There are over 40 specialized functions in this module which handle the |
| |
reading and transmission of metadata, user information (ids, names, environments, roles, |
| |
logs), file information (storage, reading, directories, extensions, replication, embedded |
| |
styles and descriptors), educational resources (course descriptions, section names and |
| |
numbers), url hashing (to assign roles on a url basis), and translating abbreviated symbols to |
| |
and from more descriptive phrases or explanations. |
| |
|
| |
This is part of the LearningOnline Network with CAPA project |
| |
described at http://www.lon-capa.org. |

| |

Counts the number of times a message log flush has been attempted (regardless |
| |
of success) by this process. Used as part of the filename when messages are |
| |
delayed. |

$type is Course (default) or Group. |

If $forcedefault evaluates to true, text returned will be default |

text for $type. Otherwise, if this is a course, the text returned |

will be a custom name for the role (if defined in the course's |

environment). If no custom name is defined the default is returned. |
