=item update() |

=item addToFilter() |
|
|
|
Convenience functions: Returns a string that adds or subtracts |
|
the second argument from the first hash, appropriate for the |
|
query string that determines which folders to recurse on |
|
|
|
=item removeFromFilter() |

=item getLinkForResource() |
|
|
|
Convenience function: Given a stack returned from getStack on the iterator, |
|
return the correct src() value. |
|
|
|
=item getDescription() |
|
|
|
Convenience function: This separates the logic of how to create |
|
the problem text strings ("Due: DATE", "Open: DATE", "Not yet assigned", |
|
etc.) into a separate function. It takes a resource object as the |
|
first parameter, and the part number of the resource as the second. |
|
It's basically a big switch statement on the status of the resource. |
|
|
|
=item dueInLessThan24Hours() |
|
|
|
Convenience function, so others can use it: Is the problem due in less than 24 hours, and still can be done? |
|
|
|
=item lastTry() |
|
|
|
Convenience function, so others can use it: Is there only one try remaining for the |
|
part, with more than one try to begin with, not due yet and still can be done? |
|
|
|
=item advancedUser() |
|
|
|
This puts a human-readable name on the env variable. |
|
|
|
=item timeToHumanString() |
|
|
|
timeToHumanString takes a time number and converts it to a |
|
human-readable representation, meant to be used in the following |
|
manner: |

the problem part is not past due, (i.e., the student could submit a different answer if |

he/she so chose). For that case completable will return 0, whereas answerable will return 1. |
