Also, there was talk about putting the fullname and section |

reduce the number of different file accesses and reduce the amount of |

HISTORY: This function originally existed in every statistics module, |
|
and performed different tasks, the had some overlap. Due to the need |
|
for the data from the different modules, they were combined into |
|
a single function. |
|
|
|
This function now extracts all the necessary course data for a student |
|
from what was downloaded from their homeserver. There is some extra |
|
time overhead compared to the ProcessStudentInformation function, but |
|
it would have had to occurred at some point anyways. This is now |
|
typically called while downloading the data it will process. It is |
|
the brother function to ProcessStudentInformation. |
|

|
|
Input: $input, $output, $data, $name |
|
|
|
$input: A hash that contains the input data to be processed |
|
|
|
$output: A hash to contain the processed data |
|
|
|
$data: A hash containing the information on what is to be |
|
processed and how (basically). |
|
|
|
$name: username:domain |
|
|
|
The input is slightly different here, but is quite simple. |
|
It is currently used where the $input, $output, and $data |
|
can and are often the same hashes, but they do not need |
|
to be. |
|
|
|
Output: None |
|
|
|
*NOTE: There is no output, but an error message is stored away in the cache |
|
data. This is checked in &FormatStudentData(). The key username:domain:error |
|
will only exist if an error occured. The error is an error from |
|
&DownloadCourseInformation(). |
